Aerospace Manufacturing Case Study: How Honscn Delivers Reliable Inconel Components for Critical Applications

Inconel 718 12-Point Flange Bolts: Built for Strength and Stability

One of the most demanding products Honscn manufactures for aerospace applications is the 12-point flange bolt made from Inconel 718.

Why Inconel 718 Is Used in Aerospace Bolts

Inconel 718 is widely used in aerospace due to its:

• Excellent high-temperature strength

• Strong resistance to creep and fatigue

• Corrosion and oxidation resistance

However, these advantages only hold true when the material is processed correctly.

Electrical Discharge Machining (EDM) for Bolt Heads

The 12-point bolt head requires precise geometry to ensure proper torque transmission. For this reason, Honscn uses Electrical Discharge Machining (EDM) to form the bolt head.

Compared to conventional machining, EDM allows:

• Higher dimensional accuracy

• Reduced mechanical stress during processing

• Better consistency on complex geometries

This ensures each bolt head meets functional and dimensional expectations.

Dedicated Heat Treatment: One Product, One Furnace

Heat treatment is a critical step for Inconel 718 fasteners. Unlike ordinary products, these aerospace bolts cannot be mixed with other parts during hardening.

At Honscn:

• Each batch of Inconel 718 bolts is heat-treated in a dedicated furnace

• No mixed loads with non-aerospace products are allowed

• Heat treatment parameters are strictly controlled and recorded

This approach ensures consistent mechanical performance across the entire batch.

Mechanical Performance Verification

After heat treatment, every batch undergoes mechanical testing. The target performance includes:

• Hardness: 42 HRC

• Tensile strength: 220 KSI

Experience has shown that if these values are not met, the bolt shank becomes vulnerable to premature failure. By strictly enforcing these benchmarks, Honscn helps customers avoid field failures caused by insufficient material strength.

Inconel 600 Rivets: Precision in High-Temperature Applications

Another key aerospace product manufactured by Honscn is rivets made from Inconel 600.

Why Inconel 600 Is Chosen

Inconel 600 offers:

• Excellent resistance to oxidation

• Stable mechanical properties at elevated temperatures

• Good workability compared to other nickel-based alloys

These characteristics make it suitable for aerospace fastening and structural applications.

Combined Automatic Lathe and CNC Machining

To achieve both efficiency and precision, Honscn uses a hybrid machining strategy:

• Automatic lathes for high-efficiency rough machining

• CNC lathes for final precision features and tight tolerances

This combination allows us to maintain consistent quality while controlling production cost — even for complex aerospace parts.

Dimensional Verification by Profile Projection

After machining, each production batch is inspected using profile projectors.

This inspection method:

• Confirms all critical dimensions match customer drawings

• Verifies geometry within specified tolerances

• Provides visual confirmation for quality records

Only parts that fully meet drawing requirements proceed to packing.

Aerospace Connectors and Related Components

In addition to fasteners and rivets, Honscn manufactures aerospace connectors and connector-related components.

These parts often require:

• Tight dimensional control

• Smooth surface finishes

• Reliable material performance

Honscn supports aerospace connector production through:

• Precision CNC machining

• Controlled surface finishing processes

• Strict in-process and final inspection

Each step is designed to ensure compatibility with mating components and stable performance in service.

What Sets Honscn Apart in Aerospace Manufacturing

Many factories can machine metal parts. Far fewer can consistently deliver aerospace-grade components.

Deep Understanding of Aerospace Materials

Honscn’s experience with nickel-based alloys such as Inconel 718 and Inconel 600 allows us to:

• Select appropriate machining strategies

• Control tool wear and cutting parameters

• Prevent material damage during processing

Material behavior is considered at every stage, not treated as an afterthought.

Process Discipline Over Speed

In aerospace projects, speed never comes before control. Honscn prioritizes:

• Documented processes

• Batch separation for critical parts

• Repeatable production conditions

This discipline reduces risk and ensures long-term consistency.

Inspection as a Value, Not a Cost

Inspection is built into the production flow, not added at the end. From in-process checks to final verification, quality control helps prevent costly rework and delays.

Supporting Customers Beyond Manufacturing

Honscn works closely with aerospace customers to support their broader goals.

Engineering Communication

Clear communication helps align expectations on:

• Tolerances and functional requirements

• Heat treatment standards

• Inspection methods and acceptance criteria

This reduces misunderstandings and shortens development cycles.

Long-Term Supply Stability

Aerospace programs often run for many years. Honscn supports long-term supply by:

• Maintaining stable production processes

• Ensuring material traceability

• Supporting repeat orders with consistent quality

Looking Ahead: Aerospace Manufacturing with Confidence

As aerospace systems become more advanced, the demands on component suppliers continue to increase. Reliability, traceability, and material expertise will remain critical.

Honscn will continue investing in:

• Advanced machining capabilities

• Process control for high-performance alloys

• Quality systems aligned with aerospace expectations

Our goal is simple: to be a manufacturing partner customers can trust for critical aerospace components.

Final Thoughts

From Inconel 718 12-point flange bolts to Inconel 600 rivets and aerospace connectors, Honscn’s experience shows that aerospace manufacturing is built on details.

By respecting materials, controlling processes, and verifying performance, we help customers reduce risk — not just cost.

For aerospace projects where reliability matters, Honscn delivers more than parts. We deliver confidence.
