Managing Thermal Expansion Tolerances and Yield Loss across Scaled High Speed Stamping Dies
Active thermal control and cryogenic substrate stabilization eliminate shut-height drift and thermal scrap loss in high-speed progressive stamping dies.
Copper Alloy Stamping
Meaning
Cold-forming process used to produce high-conductivity components for electrical and thermal applications. Utilizing copper alloy stamping allows for the mass production of terminals, connectors and heat sinks with high dimensional accuracy. This method relies on the natural ductility of the material to achieve complex shapes without cracking.
Material Ductility
Selection of the specific grade depends on the required strength and electrical performance. Successful copper alloy stamping requires a balance between the hardness of the metal and the complexity of the part design. Annealing processes are sometimes used between stages to restore workability to the metal.
Die Modification
Tooling for non-ferrous metals requires different clearances than those used for steel. Maintaining copper alloy stamping equipment involves regular polishing of the die surfaces to prevent galling. Proper lubrication reduces the friction that can lead to thinning or tearing of the material during the stroke.
Production Throughput
High-speed presses can generate thousands of parts every hour. Optimizing copper alloy stamping involves minimizing material scrap through efficient strip layout. The resulting components are ready for plating or assembly without the need for extensive secondary finishing.
Automated inspection systems verify the dimensions of the finished parts to ensure that every unit meets the strict requirements of the electronics industry.
