Products Description
Stamping parts manufacturers produce key electrical conductive components based on high-precision stamping processes, widely used in electrical products such as relays, switches, contactors, and fuses. These parts are typically made from copper strip as raw material, processed through precision die stamping and forming processes, resulting in excellent conductivity and structural consistency. In electrical systems, these products perform core functions such as conduction, connection, and current carrying at contacts; their dimensional accuracy, surface quality, and material properties directly affect the reliability and lifespan of electrical products. Through advanced die design and high-precision manufacturing processes, copper stamping parts can meet the stringent requirements of modern electrical equipment for miniaturization, high reliability, and batch consistency, making them a crucial component in the basic electrical component manufacturing system.
Technical Features
Ultra-High Die Precision
Alignment accuracy of upper and lower dies ≤0.01 mm, ensuring no misalignment or burrs in the blanking contour; blanking clearance dynamically adjusted according to material thickness (5%–8%), optimizing cross-sectional quality and die life for Copper Stamping Parts.
01
Superior Surface Quality
Cavity surface finish Ra ≤0.4 μm (mirror grade), reducing friction and wear, improving automated assembly yield; high perpendicularity of cutting edges, no corner collapse or tearing, and 30% improvement in contact resistance consistency for Metal Stamping Parts Electric Copper.
02
Ultra-Long Die Life
Key inserts use SKD11 (Japanese standard cold work die steel) and DC53 (high-toughness modified steel); after vacuum heat treatment, the hardness reaches HRC 60–62, with excellent wear resistance; the life of a single die set can reach over 30 million strokes for Copper Strip Stamping.
03
Flexible manufacturing capabilities
Supports full-size coverage from miniature signal terminals (<5mm) to high-current main terminals (>50mm); can integrate pre-plating (Sn/Ag/Ni) or local deoxidation treatment to meet subsequent welding or riveting requirements.
04

Frequently Asked Questions
Why is the blanking clearance so precise?
The blanking clearance directly affects the edge quality of the stamped part. Too small a clearance easily leads to burrs or cracks, while too large a clearance results in insufficient springback. We dynamically adjust the clearance (5%-8%) according to the copper strip thickness to achieve optimal stamping quality.
Can the die life really reach 30 million cycles?
Under normal operating conditions (room temperature, no strongly corrosive media), using SKD11 or DC53 alloy steel dies, and with a precise blanking clearance design, the die life can reach tens of millions of cycles, with minimal dimensional variation in Copper Stamping Parts.
Can these Metal Stamping Parts Electric Copper be made into complex shapes?
Through precise wire cutting technology, we can manufacture stamped parts with extremely complex shapes, and even achieve miniaturized precision components.
