The burrs on the wiring terminals are controlled within 0.04mm, and the terminals produced by our company can be controlled within 0.02. We use smaller gaps and a second chamfering method to remove burrs, achieving no burrs or burrs within 0.02 This way, during assembly, there will be no scratches on the contact between the plastic and the terminal, and there will be no scratches on the gold-plated surface, which is beneficial for the stability of conductivity
High surface smoothness Ra0.8: The surface smoothness of stamped terminals directly affects the stability of signal transmission in connectors. We purchase imported copper materials with a surface smoothness Ra of less than 0.8, and during production, the mold surface is kept flat The floating material is polished into blocks, and all surfaces in contact with the material are kept smooth without scratching the material
The dimensional accuracy of metal stamping parts refers to the error between the actual size and the basic size of the stamping parts. The smaller the error, the higher the dimensional accuracy of the metal stamping parts.
The main factors causing dimensional errors in metal stamping parts are:
1. Manufacturing accuracy of metal stamping dies
2. Assembly process of metal stamping die
3. Elastic recovery of materials after stamping
4. Accidental factors in the production process, such as inaccurate positioning, unstable material properties, etc
