03
Strong design flexibility
It can be processed into various complex shapes through mold changes, from ultra-thin copper foil pieces of 0.1mm that are widely used in flexible circuit boards and miniature electronic components to thick walled pieces of 10mm or more that are applied in large-scale electrical equipment and mechanical structural parts, and from simple flat plates for basic conductive connection and gap adjustment to complex three-dimensional structures with bending, stretching, punching, bosses and other composite features.
04
production process
Raw material preparation: We use high-quality pure copper (purple copper) that meets international standards, and can provide copper alloys such as brass/bronze as needed; All raw materials are tested for conductivity, hardness, tensile strength, and other properties. Copper coils are precision cut into standard billets, and then subjected to surface pretreatment of Metal stamping parts electric copper to remove oxide layers, oil stains, and impurities, ensuring stable stamping and consistent material properties.
Mold development: Customize specialized stamping dies based on the shape, size, and tolerance requirements of Copper stamped components, using high-strength wear-resistant die steel such as Cr12MoV, and manufactured through precision processes such as CNC machining and electrical discharge machining; Complex structural components are formed in one go using multi process composite molds, and each mold undergoes strict mold calibration before production to ensure stability and accuracy in mass production.
Stamping forming: The preprocessed copper billet is fed into high-precision stamping equipment, where pressure, speed, and stroke are precisely controlled through customized molds to complete forming processes such as punching, bending, stretching, and deep drawing, minimizing internal stress, rebound, and defects; It can achieve ultra-high dimensional accuracy of ± 0.01mm, ensuring consistency in batch Copper strip stamping and adapting to automated assembly requirements.
Surface cleaning and post-treatment: Stamping parts undergo ultrasonic cleaning, alkaline degreasing, and multiple rinses to thoroughly remove stamping oil, metal shavings, and other residues; It can be equipped with post-treatment processes such as passivation (anti oxidation discoloration), tin/silver plating (improving weldability and corrosion resistance), polishing (optimizing surface finish), etc. as needed, with strict control throughout the process to ensure that the product meets industry performance standards.
Finished product testing and packaging: Each batch of Cross copper metal stamping undergoes comprehensive testing, with high-precision measuring tools verifying dimensions, optical equipment investigating surface defects, and conductive components completing electrical performance and material verification; Qualified products are packaged in moisture-proof, oxidation resistant, and anti-static professional packaging, suitable for international long-distance transportation. At the same time, neutral packaging and customized packaging solutions can be provided to ensure storage and transportation safety.
Application scenarios
Electrical switches field
Copper spring contacts are widely used in household, commercial, and industrial wall switches, socket modules, and internal structural components of smart switches. As the core carrier of switch contacts, these stamped parts are responsible for the connection and disconnection of circuits, ensuring stable current transmission under the touch switch, and solving problems such as ignition and failure caused by poor contact.
