Aluminum Alloy Hardware Stamping Processing Guide

Aluminum alloy stamping processing requires special attention to process control due to its special material properties. Compared with steel, aluminum alloy is softer and more expensive, and is prone to breakage during processing. Some products also require subsequent secondary processing. In order to ensure product quality and production efficiency, the key points of aluminum alloy stamping processing are summarized as follows:

1. Key points for material selection

1) Reasonably control the hardness of aluminum plate: It is recommended to give priority to aluminum materials with lower hardness such as 1 series, 3 series, and 5 series; for aluminum materials with higher hardness such as 6 series and 7 series, annealing treatment to O state is required before processing.

2) Scientifically select material thickness: Under the premise of meeting product performance requirements, use thinner aluminum plates as much as possible.

2. Process design specifications

1) Punching process arrangement: The punching process should be arranged at the back as much as possible. For products with a large number of holes, a special punching process can be considered.

2) R angle design standard: The R angle of the bent part should not be too small to prevent cracking.
3) Texture direction control: The stamping direction should be perpendicular to the rolling texture of the aluminum plate.
4) Reverse folding treatment: avoid pressure line design, widen the pressure line and reduce the depth when necessary.

3. Production site management
1) Use of stamping oil: Stamping oil should be used appropriately during processing, which is beneficial to heat dissipation and can ensure smooth punching.
2) 5S management requirements: Keep molds, equipment, production lines, and packaging clean, and regularly remove sharp debris.
3) Timing of surface treatment: Workpieces that require surface treatment such as wire drawing must be carried out after the forming process is completed.

4. Key points of quality control
1) Establish a first-article inspection system
2) Implement process inspection mechanism
3) Improve finished product inspection standards

The systematic implementation of the above measures can effectively improve the yield rate of aluminum alloy stamping parts.KAIYA has 15 years of experience in precision metal parts manufacturing, introduced advanced production management systems, equipped with a professional process design team and a complete quality control system, and can provide customers with high-quality products and reliable delivery guarantees.
