Characteristics of precision metal stamping parts:

1. Complex in shape, with high precision in size and position. The general material thickness is t>3mm~12.5mm, which is the precision punching part of medium and thick plates. The cutting surface is flat and smooth, with quality comparable to cutting processing.

2. The contour is clear, the collapse angle is small, the hole edge distance and hole spacing (wall thickness) are ≤ t, and there are formed precision punched parts such as pressure convex, countersunk, blind hole, hub flange, etc., especially high-precision gear precision punched parts with small module involute, cycloid, triangle, rectangle, trapezoid and other shapes.

3. All components of electromechanical products are produced on a large scale to achieve a moderate economic production scale, including precision punched parts for automotive handbrakes, cars, motorcycles, and other products. Finished parts are stamped from raw materials without cutting or processing.

4. Due to the cold hardening effect, the surface hardness and strength are greatly improved, and the friction resistance and weather resistance are enhanced. The service life of precision metal stamping parts such as moving surfaces, friction surface gears, and shaft sleeves will be improved.
