Internal Capability

 

Every custom nut begins with an idea.

Bringing that idea to life requires more than equipment—

it takes expertise, precision, and a well-controlled manufacturing process.

From tooling design to final inspection, our in-house capabilities are built to

ensure reliable quality, stable production, and the flexibility to meet diverse customer requirements.

 

 

Tooling Design

 

We have over 3 skilled tooling designers in team.

Continuous knowledge transfer ensures long-term stability you can rely on.

 

 

Cold/Warm Forming

 

We have 41 Sets of Nut Former with 5 to 6 forming stations

Specialize in Cold Forming & Warm Forming

Capability:   

M3 to M36 (#5 to 1-1/4”)

Max. OD 56mm & Max. Overall Length 120mm

Available Material:  

Carbon Steel, Alloy Steel,

Stainless Steel, Brass, Aluminum

Cold and warm forming technologies represent the core manufacturing capabilities of our specialty nuts production.

In nut manufacturing, tooling design and forming process plays a critical role in defining the geometry and performance of the final product. They form the foundation of most product characteristics, including structural integrity and dimensional accuracy.

Through in-house tooling development and process control, we ensure stable production quality while meeting diverse customer requirements across standard and highly customized nut designs.

Tapping Thread

 

13 sets of Reciprocating Type of Tapping Thread Machine

Cut Thread & Formed Thread

Capability:

M6~M34

Process error detecting:

Torque monitor of servo motor

 

 

CNC

 

2 sets of CNC

Quick Prototype & Rework

Key process for Highly confidential precision product, such as our 316Ti flare nuts for hydraulic applications.

 

 

Tumble De-burring & Sand Blasting

 

During the forming process or subsequent CNC machining, slight burrs or sharp edges may occur as a result of material flow requirements or the precise machining of local dimensions.

These burrs and sharp edges can be removed through tumbling deburring and sand blasting processes.

 

 

Laser Marking

 

3 sets of laser marking machine.

Workable material:

Stainless steel

Coated/Plated Carbon steel

Aluminum

Brass

Our laser marking machines have been widely applied across various stainless steel and galvanized custom nut products, supporting customers with precise identification and traceability requirements.

Typical applications include:

Stainless steel custom lock nuts, where manufacturer’s identification and material code are marked on the bearing surface or hex flat.

Precision stainless steel tube nuts and flare nuts, where customer identification, material code, and series number are laser marked on the bearing surface or hex flat for full traceability.

Galvanized custom nuts, where manufacturer’s identification and part number are marked on the bearing surface or hex flat to meet production and quality control requirements.

 

 

Optical Sorting

 

10 sets of Optical Sorting Machine, including 1 set of AI Optical Sorting Machine.

Equipped with 4~10 cameras

AI sorting applied for:  surface defects, cracks, thread damage and other defects trainable with images. 

This technology represents a key step toward reducing reliance on manual inspection, significantly improving efficiency in detecting surface defects and ensuring consistent product quality.

100% Optical sorting available before delivery (Except for overweight product).

 

 

 

Automatic Internal Thread Sorting

We never stop innovating and advancing.
The internal thread engagement verification capability will be officially launched in 2026.

2 sets of Automatic Internal Thread Sorting Machine, currently in trial run.

Simulate artificial torque

100% data-driven verification

 

 

Manual Sorting

 

For specific quality & packaging requirements:

◇ Needs of 100% sorting by Gauge

◇ Large-sized product

Too big to be optical sorted

◇ External threaded product

To avoid thread damage caused by optical sorting

◇ Surface defects sorting

◇ Remove burrs at thread beginning

◇ Customized small packaging

 

 

Packaging

 

Semi-automatic Carton Sealing / Filling machine reduces manual labor and improves packaging efficiency.

European / American standard packaging available

Customized packaging available
