PRODUCT PROCESS
Material selection | Copper material standards: Select high-purity copper materials that meet international standards to ensure that the purity of the material reaches more than 99.9% to provide the best conductivity. |
Physical properties: The copper material should have excellent ductility and toughness to facilitate subsequent processing procedures while ensuring the stability of the fuse under high current. |
Chemical stability: Select copper materials that are not easily oxidized to reduce chemical changes during processing and use, and maintain the long-term performance of the contact knife. |
Precision processing | Cutting: Use a high-precision cutting machine to make preliminary cuts on the copper material to ensure the dimensional accuracy of the contact knife. |
Forming: The copper material is formed into the desired contact knife shape through stamping or casting processes. This step requires precision molds and equipment to ensure the consistency of the shape. |
Polishing: Polish the formed contact blade to remove burrs and surface defects, improve the surface finish of the fuse copper cap, and reduce contact resistance. |
Heat treatment: Perform appropriate heat treatment to improve the microstructure of the copper material and improve its hardness and wear resistance. |
Quality inspection | Dimension inspection: Use precision measuring tools such as calipers and micrometers to inspect the dimensions of the contact blade to ensure that the dimensions meet the design requirements. |
Conductivity test: Use resistance testing instruments to detect the conductivity of the contact blade to ensure that it meets the needs of high current transmission. |
Durability test: Simulate actual use conditions and conduct durability tests on the contact blade, including performance evaluation under environmental conditions such as high temperature and high humidity. |
Fuse performance test: Test the fuse performance of the contact blade under overload conditions to ensure that it can safely fuse within the specified time to protect the circuit. |
Quality control process | Incoming material inspection: Strict quality inspection of all raw materials entering the production line to ensure that the materials meet production standards. |
Process control: Set quality control points in each processing step to monitor the product in real-time to detect and solve problems in a timely manner. |
Finished product inspection: After completing all processing procedures, the product is comprehensively inspected, including appearance, size, performance, and other aspects. |
Traceability system: Establish a complete product traceability system to record the production batch, processing parameters, and other information of each product, so that problems can be quickly located and solved when they occur. |
OUR ADVANTAGES
Packaging material selection
· Internal packaging:
Plastic packaging: Use anti-static and anti-corrosion plastic materials such as polyethylene bags or plastic boxes to protect the copper caps from moisture, dust, and other environmental factors.
· External packaging:
Cartons: Choose sturdy five-layer corrugated cartons to provide additional protection and support. The cartons should have good pressure resistance and impact resistance.
Pallet: For large quantities of copper caps, use pallets for loading to facilitate forklift handling and stacking.
Transportation method
Land transportation: For short-distance or domestic transportation, use trucks or vans for transportation to ensure the stability and safety of the transportation tool.
Air transportation: For international transportation or urgent needs, choose air transportation to shorten transportation time.
Ocean transportation: For large quantities of goods, consider using ocean transportation to reduce transportation costs.
