Cold Forging

1. Enhanced Material Strength

Cold forging induces *strain hardening*, strengthening the metal’s grain structure. The result? Components with exceptional durability, fatigue resistance, and load-bearing capacity-perfect for high-stress applications.

2. Cost-Effective Production

Say goodbye to wasted materials! Cold forging achieves near-net-shape precision, minimizing scrap and reducing machining needs. Lower energy consumption (no heating!) further slashes operational costs.

3. Superior Surface Finish & Precision

Enjoy flawlessly smooth surfaces and tight dimensional tolerances right out of the press. Secondary finishing steps? Often eliminated, speeding up your production timeline.

4. Eco-Friendly Manufacturing

With no furnaces or excessive energy use, cold forging reduces carbon footprints. Less material waste also supports sustainable practices-ideal for eco-conscious industries.

5. High-Speed Scalability

Automated cold forging systems produce thousands of identical parts per hour, ensuring consistent quality for mass production without compromising performance.

From automotive gears and aerospace fasteners to electronic connectors and medical devices, cold forging delivers components that meet the toughest standards. Whether you need lightweight alloys or high-strength steel, this process adapts to your material and design requirements.

• Longer product life spans due to enhanced mechanical properties.
  

• Faster ROI with reduced per-unit costs and minimal post-processing.

• Design flexibility for complex geometries and custom specifications.

1. Cold Forging Technical Parameters

Cold forging is a metalworking process performed at or near room temperature to shape materials into high-strength components. Key technical parameters include:

1.1 Material Properties

Yield Strength: Must be within forgeable limits (typically < 1,200 MPa).

Ductility: Requires sufficient elongation (e.g., >10% for most steels).

Work Hardening Rate: Affects deformation behavior (e.g., austenitic stainless steel has high work hardening).

1.2 Process Parameters

Forming Temperature: Room temperature (20–30°C), with optional preheating up to 250°C for high-strength alloys.

Die Design:

Die material: Tool steel (e.g., AISI D2, DIN 1.2379).

Tolerance: ±0.1 mm for precision components.

1.3 Post-Processing

Heat Treatment: Stress relief annealing (200–400°C).

Surface Finish: Ra 0.8–3.2 μm after forging.
