Project Introduction
In order to optimize the structure of the sliding shaft, the customer needed a miniature thumb screw with a thread length of only 2mm. Because the thread is too short, it is difficult to form it in one go using traditional lathes, and many manufacturers rejected the order due to its high complexity. After the customer learned about our precision machining capabilities through Facebook, they commissioned the development of this product.

Cooperation results:
- Successfully delivered two customized screws, and the matching customized shafts were shipped simultaneously
- The customer placed additional orders and established a long-term cooperative relationship
Challenges and Solutions
Challenge 1: Ultra-short thread processing technology
- Difficulty: The thread length is only 2mm, and traditional lathes cannot process it directly, which can easily cause thread deformation or breakage.
- Solution:
- Step-by-step processing: Process 10mm thread in the first process, leaving room for subsequent cutting
- Secondary finishing: Manually shorten the thread to 2mm piece by piece, and calibrate with high-precision testing equipment
- Process optimization: Use CNC lathe + customized fixture to reduce processing errors
Challenge 2: Surface treatment consistency
- Difficulty: Anodized red needs to be uniform in batch color to avoid batch differences.
- Solution:
- Fully automated anodizing line, strictly control current and time parameters
- Sampling each batch to test color fastness and film thickness to ensure compliance with ASTM standards
Challenge 3: Delivery cycle pressure
- Difficulty: Customers require proofing and mass production to be completed within 30 days.
- Solution:
- Enable multiple CNC equipment for parallel production to compress the processing cycle
- Prioritize the deployment of technical teams for manual finishing to ensure efficiency
Customer Comments
"Before contacting your company, we almost gave up the development of this screw. Thank you for your team breaking through the technical limitations. Not only did you achieve high-precision processing of 2mm threads, but the appearance and delivery speed also exceeded expectations! For all subsequent precision parts orders, we will give priority to your cooperation."
