Non-standard copper screw

Non-standard copper screws refer to copper screws customized according to specific requirements, whose sizes and specifications do not belong to national standards (such as GB, DIN, etc.). It is different from the common standard screw, there is no fixed uniform size, usually need to be processed and produced according to the drawings or specific requirements provided by customers. Because of its customizability, non-standard copper screws are widely used in various situations requiring special fasteners, such as: -Precision machinery: such as clocks and watches, instruments and equipment, mold closing machines, etc. 4. -Electronic appliances: used to fix internal components 5 in electronic products, electrical equipment and switches. -Aerospace and automotive manufacturing: for fixing and connecting precision components6. -Other fields: including furniture decoration, leather goods connection, shipbuilding, etc. Production and customization process The production of non-standard copper screws usually requires the following steps: 1. Confirm the parameters: communicate with the customer to clarify the detailed size, material, surface treatment, tolerance and other requirements of the screw. 2. Design and drawing: draw or confirm three-dimensional drawings according to customer requirements as the basis for production. 3. Select the material: select the appropriate copper alloy material according to the functional requirements. 4. Processing and manufacturing: through turning, cutting, tapping and other processes to produce 56. 5. Surface treatment: carry out gold plating, silver plating, tin plating, nickel plating and other environmentally friendly electroplating according to the requirements, or adopt passivation, electrophoresis and other methods to enhance corrosion resistance and appearance quality. 6. Quality inspection: inspect the size, thread, mechanical properties and other aspects of the finished products to ensure that they meet customer standards.
