3D printing has been applied since the 1980s, just over 30 years, 3D printing this emerging technology has been applied to a number of industries. With the improvement of people's demand for personalized and customized automotive products, as well as the difficulties such as the long time and high cost of manufacturing and maintenance of some traditional complex process parts, 3D printing technology is increasingly favored by auto companies, parts and after-sales service suppliers. As we all know, the automobile industry is a typical capital and technology-intensive industry, and the investment in new car research and development is also very large. As a result, car companies, parts and after-sales service suppliers are actively exploring new technologies to reduce material costs and improve efficiency. 3D printing technology then began to explore and apply in the field of automotive parts, especially in automobile manufacturing and maintenance has become more and more mature.
3D printing technology
Definition of 3D printing technology
3D printing technology is a kind of digital model file based on the use of powder metal or plastic and other adhesive materials, through the 3D printer, layer by layer to construct the object technology. This technology allows us to convert digital models into physical objects through CAD (computer Aided design) software. Applications of 3D printing technology include manufacturing, medical fields and so on.
The advantages of 3D printing technology
1. Rapid Prototyping: 3D printers offer rapid prototyping, allowing you to quickly design, produce, and test custom parts, and quickly modify designs without affecting the speed of the printing process.
2. Design freedom: 3D printing allows you to make complex geometric shapes that are difficult to make with traditional manufacturing methods. You can easily modify the design and make any type of geometry.
3. Reduce waste: 3D printing uses an additive manufacturing process, where the only materials used are those needed to produce the required parts. Traditional processing methods cut large chunks of non-recyclable material to produce parts, resulting in a lot of waste.
4. Cost: Due to the reduction of material waste, 3D printing reduces production costs because you only pay for the materials you need to print.
5. Print on demand: 3D printing allows you to print on demand, avoiding inventory overhangs and costly inventory. It uses just-in-time inventory management technology to free up inventory space by printing designs in the exact amount needed only when needed.
6. Speed: 3D printing can print parts in as little as a few hours, depending on the complexity and part size, while processing can take much longer.
7. Provide more manufacturing options: 3D printing methods offer a wide range of manufactured products. It can produce individually designed and customized products.
8. Lighter: Plastic materials used in 3D printing are much lighter than metal. Many cars use 3D printed parts to make their vehicles lighter and more fuel efficient.
9. Save on warehousing costs: 3D printing only produces products on demand, so you don't have to worry about storage space or warehouses with excess stock.
10. Create more jobs: The widespread use of 3D printing will create jobs for engineers to design equipment and technicians who will maintain inventory and solve problems. More artists will rely on the use of 3D printing to deliver their products.
Disadvantages of 3D printing technology
1. Not suitable for mass production: If a large number of parts need to be produced, then 3D printing is not an ideal production process. Other methods, such as injection molding, may be cost-effective for printing large parts.
2. Limited materials: Only specific plastics with certain mechanical properties can be used to produce 3D printed parts. Some 3D printers can use metal, and metal options are limited.
3. Limited build volume: Most 3D printers have small build rooms, and if your printed parts are larger than the build printer room, you'll have to split those parts into multiple parts and glue them together during post-processing.
4. Large print costs increase: If your print is larger than the build room, the cost of printing will increase because the print will take longer. The process also requires manual labor.
5. Fewer manufacturing jobs: 3D printing will lead to fewer manufacturing jobs, which will have an impact on third world economies, especially those that rely on low-skilled jobs.
6. Copyright issues: Increased use of 3D printing mechanisms can lead to a lot of copyright issues. It will open the door to more counterfeit products, especially if the products exist in digital files.
7. Post-processing: 3D printing needs to be cleaned to remove supporting materials and make the surface of the produced parts smooth. This slows down the process.
8. Manufacture of dangerous goods: Without proper regulation, 3D printing can lead to the manufacture of dangerous goods such as guns and counterfeit money. The production process can also undermine control mechanisms.
9. Printing useless items: 3D printing can lead to the manufacture of environmentally unfriendly useless items.
10. Part structure: In the additive manufacturing process, parts are printed in layers and must be bonded to each other during the printing process. If the layers separate, the part will break.
/ what are the applications of 3D printing in the automotive industry?
01. Make vehicle spare parts
Because the car will be damaged and need to be repaired, 4S shops and auto repair shops will prepare some parts. However, because there are too many car parts, it is impossible to reserve every part, and inventory costs will be high. The small market with few manufacturers also leads to prolonged maintenance time.
Therefore, 3D printing parts has become a new way of spare parts, and the store can print the required parts directly in the store, which makes it possible to reduce inventory pressure and reduce maintenance time.
On the one hand, it reduces the inventory pressure, and on the other hand, it saves the time of ordering parts and improves the maintenance efficiency.
In the future, parts warehouses are likely to be dominated by digital models.
02. Make product samples
Automobile as a comprehensive product of modern industrial civilization, from design to mass production, research and development during the need to produce a large number of samples. Before 3D printing, these samples were processed by hand, CNC and other methods.
At present, in the development stage, there are already a large number of samples are produced by 3D printing. With the advancement of 3D printing technology, the advantages of short production cycle, high precision and low cost will be further highlighted.
03. Mass production of parts
At present, 3D printed parts are still relatively few directly applied to mass production vehicles, and most of them are still used as test parts.
It is not that the quality of 3D printed parts is not good, but the current 3D printing speed can not meet the needs of mass production.
Therefore, the current 3D printed parts are only used in some relatively small production models, such as various supercars, F1 cars, and as modified parts.
Due to the high degree of customization and small molding limitations of 3D printing, some topologically optimized parts can be manufactured, which often have complex geometry, lighter and better performance than the original parts.
At present, the top manufacturers in the automotive industry are increasing their investment in the research and development of 3D printing technology. It is hoped that 3D printing technology can be used to mass produce parts and bring better performance to cars.
04. Realize distributed production mode
As we all know, the automotive industry is a highly concentrated industry, a large number of parts are shipped to factories, assembled on the production line into complete vehicles, and then shipped around the world for sale.
The transportation involved takes a lot of time and money. For example, the new French car Citroen is concentrated in Chengdu production, and then sent to global sales.
3D printing can realize distributed production, and the chassis and various parts can be 3D printed locally and then assembled.
05. Print the whole car
From the current point of view, the printed vehicle is still a certain distance from mass production, but over the years, a variety of 3D printed cars and electric vehicles are also a lot.
The current 3D printing technology can already be used to print the whole vehicle chassis, frame, door, etc., and the 3D printed chassis and other parts can be integrated with multiple parts and printed in one, which can not only reduce the assembly time, but also improve the firmness.
However, it is currently limited by the printing speed and does not have the capacity for mass production. When the printing speed increases to a certain stage, 3D printing production cars are not impossible.
From these perspectives, when 3D printing technology is developed to a certain extent, the future impact on the automotive industry will be enormous.
Now many industries of precision parts will use CNC machining production, but after CNC machining is completed, many products surface is still relatively rough, this time you need to carry out secondary surface finishing treatment.
First of all, surface treatment is not suitable for all CNC processing products, some products can be directly used after processing, and some need to be hand-polished, electroplating, oxidation, radium carving, screen printing, powder spraying and other special processes. Here are some things you should know about surface treatment.
1, improve product accuracy; After the product processing is completed, some products have a rough surface and leave a large residual stress, which will reduce the accuracy of the product and affect the precision of the match between the parts. In this case, the product surface treatment is required.
2, provide product wear resistance; If the parts usually use scenarios are interacting with other parts, long-term use will increase part wear, which also requires processing of the product surface to extend the service life of the parts.
3, improve the corrosion resistance of the product; Parts used for a long time in highly corrosive places require special surface treatment, requiring polishing and spraying of anti-corrosion materials. Improve corrosion resistance and service life of the product.
The above three points are the prerequisites for surface processing after CNC precision parts processing, and several surface treatment methods will be introduced below.
What is electroplating? What are the types and applications of electroplating?
01. What is electroplating?
Electroplating refers to the surface engineering technology of obtaining a solid metal film on the surface of the substrate by electrolysis in a salt solution containing the metallized group, with the metallized group as the cathode and the metallized group or other inert conductor as the anode under the action of direct current.
02. Why electroplate?
The purpose of electroplating is to improve the appearance of the material, while giving the surface of the material a variety of physical and chemical properties, such as corrosion resistance, decorative, wear resistance, brazing and electrical, magnetic, optical properties.
03. What are the types and applications of electroplating?
1, galvanized
The galvanized layer is of high purity and is an anodic coating. The zinc layer plays a mechanical and electrochemical protective role on the steel matrix.
Therefore, galvanized layer is widely used in machinery, hardware, electronics, instruments, light industry and other aspects, is one of the most widely used plating species.
2. Copper plating
The copper coating is a cathode polar coating, which can only play a mechanical protection role on the base metal. The copper plating layer is usually not used as a protective decorative coating alone, but as the bottom or middle layer of the coating to improve the adhesion between the surface coating and the base metal.
In the field of electronics, such as through hole copper plating on printed circuit boards, as well as hardware technology, crafts, furniture decoration and other fields.
3. Nickel plating
Nickel plating layer is a negative polarity protective layer, which only has a mechanical protection effect on the base metal. In addition to the direct use of some medical devices and battery shells, the nickel-plated layer is often used as the bottom or middle interval layer, which is widely used in daily hardware, light industry, home appliances, machinery and other industries.
4. Chrome plating
The chromium-plated layer is a negative polarity coating, which only plays a mechanical protection role. Decorative chrome plating, the bottom layer is generally polished or electrodeposited bright coating.
Widely used in instruments, meters, daily hardware, household appliances, aircraft, automobiles, motorcycles, bicycles and other exposed parts. Functional chrome plating includes hard chrome plating, porous chrome, black chrome, opal chrome and so on.
Hard chrome layer is mainly used for various measuring calipers, gauges, cutting tools and various types of shaft, loose hole chrome layer is mainly used for cylinder cavity piston failure; The black chrome layer is used for parts that need a dull surface and wear resistance, such as aviation instruments, optical instruments, photographic equipment, etc. Opalescent chromium is mainly used in various measuring tools.
5. Tin plating
Compared to the steel substrate, tin is a negative polar coating, while compared to the copper substrate, it is an anode coating. The tinning layer is mainly used as the protective layer of thin plate in the can industry, and most of the malleable iron skin is made of iron plate tinning. Another major use of tin coatings is in the electronics and power industries.
6, alloy plating
In a solution, two or more metal ions are co-precipitated on the cathode to form a uniform fine coating process called alloy plating.
Alloy electroplating is superior to single metal electroplating in crystal density, porosity, color, hardness, corrosion resistance, wear resistance, magnetic conductivity, wear resistance and high temperature resistance.
There are more than 240 kinds of electroplating alloys, but less than 40 kinds are actually used in production. It is generally divided into three categories: protective alloy coating, decorative alloy coating and functional alloy coating.
Widely used in aviation, aerospace, navigation, automobile, mining, military, instruments, meters, visual hardware, tableware, Musical Instruments and other industries.
In addition to the above, there are other chemical plating, composite plating, non-metal plating, gold plating, silver plating and so on.
What is polishing?
The surface of the items processed by CNC machining or 3D printing is sometimes rough, and the surface requirements of the products are high, so they need to be polished.
Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece in order to obtain a bright, flat surface processing method.
Polishing can not improve the dimensional accuracy or geometric accuracy of the workpiece, but for the purpose of obtaining a smooth surface or mirror gloss, and sometimes to eliminate gloss (extinction).
Several common polishing methods are described below:
01. Mechanical polishing
Mechanical polishing is by cutting, plastic deformation of the surface of the material to remove the polished convex and smooth surface polishing method, the general use of whetstone strip, wool wheel, sandpaper, etc., mainly manual operation, surface quality requirements can be used to super-fine polishing method.
Super finishing polishing is the use of special grinding tools, in the polishing liquid containing abrasive, tightly pressed on the workpiece to be machined surface, for high-speed rotation. This method is often used in optical lens molds.
02. Chemical polishing
Chemical polishing is to dissolve the microscopic protruding part of the surface of the material in the chemical medium preferentially than the concave part, so as to obtain a smooth surface.
The main advantage of this method is that it does not require complex equipment, can polish the workpiece with complex shape, and can polish many workpieces at the same time, with high efficiency.
The core problem of chemical polishing is the preparation of polishing liquid.
03. Electrolytic polishing
The basic principle of electrolytic polishing is the same as that of chemical polishing, that is, the surface is smooth by selectively dissolving small protruding parts on the surface of the material.
Compared with chemical polishing, the effect of cathode reaction can be eliminated and the effect is better.
04. Ultrasonic polishing
The workpiece is put into the abrasive suspension and placed together in the ultrasonic field, and the abrasive is ground and polished on the workpiece surface by relying on the oscillation of the ultrasonic wave.
Ultrasonic processing macroscopic force is small, will not cause workpiece deformation, but tooling production and installation is more difficult.
05. Fluid polishing
Fluid polishing relies on high-speed flowing liquid and the abrasive particles it carries to wash the surface of the workpiece to achieve the purpose of polishing.
Common methods are: abrasive jet processing, liquid jet processing, hydrodynamic grinding and so on. Hydrodynamic grinding is driven by hydraulic pressure to make the liquid medium carrying abrasive particles flow through the surface of the workpiece at high speed.
The medium is mainly made of special compounds with good flow under low pressure and mixed with abrasives, which can be silicon carbide powder.
06. Magnetic grinding polishing
Magnetic grinding and polishing is the use of magnetic abrasive under the action of magnetic field to form an abrasive brush, grinding the workpiece.
This method has the advantages of high processing efficiency, good quality, easy control of processing conditions and good working conditions.
The above are 6 common polishing processe.

General steps of plastic parts designPlastic parts are designed on the basis of industrial modeling. First, see whether there are similar products for reference, and then carry out detailed functional decomposition of products and parts to determine the main process problems such as parts folding, wall thickness, demoulding slope, transition treatment between parts, connection treatment and strength treatment of parts.1. Similar reference
Before design, first look for similar products of the company and peers, what problems and deficiencies have occurred in the original products, and refer to the existing mature structure to avoid problematic structural forms.2. Determine the part discount, transition, connection and clearance treatment between partsUnderstand the modeling style from the modeling drawing and effect drawing, cooperate with the functional decomposition of the product, determine the number of parts (different surface states are either divided into different parts, or there must be over treatment between different surfaces), determine the over treatment between parts' surfaces, and determine the connection mode and fit clearance between parts.
3. Determination of part strength and connection strengthDetermine the wall thickness of the part body according to the product size. The strength of the part itself is determined by the wall thickness of the plastic part, the structural form (the plastic part in the shape of a flat plate has the worst strength), the stiffener and the stiffener. While determining the single strength of parts, the connection strength between parts must be determined. The methods to change the connection strength include: adding screw column, adding stop, adding buckle position and adding reinforcing bone against top and bottom.4. Determination of demoulding slope
The demoulding slope shall be comprehensively determined according to the material (PP, PE silica gel and rubber can be demoulded forcibly), surface state (the slope of decorative grain shall be greater than that of smooth surface, and the slope of etched surface shall be 0.5 degrees greater than that required by the template as far as possible, so as to ensure that the etched surface will not be damaged and improve the yield of products), transparency or not determines the demoulding slope of parts (the transparent slope shall be greater).Material types recommended by different product series of the companySurface treatment of plastic parts
Wall thickness selection of plastic partsFor plastic parts, the uniformity of wall thickness is required, and the workpiece with uneven wall thickness will have shrinkage traces. It is required that the ratio of stiffener to main wall thickness should be less than 0.4, and the maximum ratio should not exceed 0.6.Demoulding slope of plastic parts
In the construction of stereoscopic drawing, where the appearance and assembly are affected, the slope needs to be drawn, and the slope is generally not drawn for stiffeners.The demoulding slope of plastic parts is determined by the material, surface decoration status and whether the parts are transparent or not. The demoulding slope of hard plastic is greater than that of soft plastic. The higher the part, the deeper the hole, and the smaller the slope.Recommended demoulding slope for different materials
Numerical values of different accuracy in different size rangesDimensional accuracy of plastic partsGenerally, the accuracy of plastic parts is not high. In practical use, we mainly check the assembly dimensions, and mainly mark the overall dimensions, assembly dimensions and other dimensions that need to be controlled on the plan.
In practice, we mainly consider the consistency of dimensions. The edges of the upper and lower covers need to be aligned.Economic accuracy of different materialsNumerical values of different accuracy in different size ranges
Surface roughness of plastics1) The roughness of the etched surface cannot be marked. Where the plastic surface finish is particularly high, circle this range and mark the surface state as mirror.2) The surface of plastic parts is generally smooth and bright, and the surface roughness is generally ra2.5 0.2um.
3) The surface roughness of plastic mainly depends on the surface roughness of mold cavity. The surface roughness of mold is required to be one to two levels higher than that of plastic parts. The mold surface can reach ra0.05 by ultrasonic and electrolytic polishing.FilletThe fillet value of injection molding is determined by the adjacent wall thickness, generally 0.5 1.5 times of the wall thickness, but not less than 0.5mm.
The position of the parting surface shall be carefully selected. There is a fillet on the parting surface, and the fillet part shall be on the other side of the die. It is difficult to make, and there are fine trace lines at the fillet. However, fillet is required when anti cutting hand is required.Stiffener problemThe injection molding process is similar to the casting process. The non-uniformity of wall thickness will produce shrinkage defects. Generally, the wall thickness of reinforcement is 0.4 times of the main body thickness, and the maximum is no more than 0.6 times. The spacing between bars is greater than 4T, and the height of bars is less than 3T. In the method of improving the strength of parts, it is generally reinforced without increasing the wall thickness.
The reinforcement of the screw column shall be at least 1.0mm lower than the end face of the column, and the reinforcement shall be at least 1.0mm lower than the part surface or the parting surface.When multiple bars intersect, pay attention to the non-uniformity of wall thickness caused by the intersection.Design of stiffeners for plastic parts
Bearing surfacePlastic is easy to deform. In terms of positioning, it should be classified as the positioning of wool embryo. In terms of positioning area, it should be small. For example, the support of plane should be changed into small convex points and convex rings.Oblique roof and row position
The inclined top and row position move in the parting direction and perpendicular to the parting direction. The inclined top and row position shall be perpendicular to the parting direction, and there shall be sufficient movement space, as shown in the following figure:Treatment of plastic limit process problems1) Special treatment of wall thickness
For particularly large workpieces, such as the shell of toy cars, the wall thickness can be relatively thin by using the method of multi-point glue feeding. The local glue position of the column is thick, which is treated as shown in the following figure.Special treatment of wall thickness2) Treatment of small slope and vertical surface
The die surface has high dimensional accuracy, high surface finish, small demoulding resistance and small demoulding slope. In order to achieve this purpose, the parts with small inclination of the workpiece are inserted separately, and the inserts are processed by wire cutting and grinding, as shown in the figure below.To ensure that the side wall is vertical, the running position or inclined top is required. There is an interface line at the running position. In order to avoid obvious interface, the wiring is generally placed at the junction of fillet and large surface.Treatment of small slope and vertical surface
To ensure that the side wall is vertical, the running position or inclined top is required. There is an interface line at the running position. In order to avoid obvious interface, the wiring is generally placed at the junction of fillet and large surface.Problems often to be solved for plastic parts1) Transition processing problem
The accuracy of plastic parts is generally not high. There must be transition treatment between adjacent parts and different surfaces of the same part.Small grooves are generally used for transition between different surfaces of the same part, and small grooves and high-low staggered surfaces can be used between different parts, as shown in the figure.Surface over treatment
2) Clearance value of plastic partsParts are directly assembled without movement, generally 0.1mm;The seam is generally 0.15mm;
The minimum clearance between parts without contact is 0.3mm, generally 0.5mm.3) The common forms and clearance of plastic parts are shown in the figureCommon forms and clearance taking method of stop of plastic parts
Strategic Plan You should consider whether or not you are looking for a long term relationship. You need to locate a good cultural and strategic fit. Do your due diligence and take your time in uncovering a manufacturers professional reputation in that industry. During your research, don't just look at the positive reviews to determine how good they are, look for the red flags and see how bad things can get.
The Process Type Different manufacturers use different manufacturing processes that include extrusion, co-extrusion, tri-extrusion as well as crosshead extrusion coatings.
The Plastic Materials The plastic extrusion materials are used in different applications and each of them has their unique properties. One of the most important aspects of hiring a manufacturer is considering the extrusion materials they use for the custom parts. You have to be sure that the parts will be manufactured successfully and will perform as properly as is expected. In case you are not sure about the kind of plastic extrusion materials that would be best for your parts, an engineer can assist you in that area. There are also numerous grade types for the extrudable materials so you should choose a company that can produce the grade you need.
Capabilities If you have a significant production volume requirement, it is essential to know the production capabilities of the manufacturer. The manufacturer should also be able to provide you with extensive capabilities in terms of the design, tooling and fabrication. With these plastic extrusion capabilities, a manufacturer is able to produce high quality custom parts that meet the requirements of their customers. The finishes should be considered as well as they could be matt, glossy or textured. That means your custom plastic parts manufacturer should know about the latest finishes in the market.
Tooling Custom plastic extrusion needs tooling, which is a lot cheaper compared to injection molding. A quality extrusion manufactures ought to offer you state of the art tooling capabilities. They should have an experienced team that designs, engineers and tests all tooling. This will improve productivity, efficiency, safety and reduce costs.
Customer Service When working with any manufacturer, the process will become easier if they have working customer services that communicate effectively. A great manufacturing company is determined by the quality of customer services they offer. If for instance you have any last minute requests or want to change your order, you need to know that someone will be there to attend to you and support you. This will be more important if you are looking for a long term relationship. For it to be successful custom plastic parts manufacturer there needs to be helpful and pleasant customer service.
Conclusion You must consider these things when you are looking for the right manufacturer. As long as you evaluate their previous work and ensure they can provide you with all your requirements at a reasonable price, you will find a good company to work with.
