Explanation Of The Strength Of Cold-pressed Needle Material

crimp contact In the design and manufacturing process, the mechanical properties of the materials are particularly important. For different plastic substrates and inserts, an ideal connection can only be achieved when the load-bearing capacity between the crimp contact pin body metal and the plastic melt matches the overall structure.

contact socket crimp The metal material on which the connection relies must possess stable hardness and tensile strength. The Brinell or Rockwell hardness of the material provides a basis for measuring its resistance to indentation and shear failure. If steel or alloys with moderate hardness are used, their bending and shear strengths are sufficient to withstand the thermal expansion and contraction and mechanical loads during the injection molding, cooling, and long-term use of the plastic part.

Meanwhile, the matching degree between the design of the threads, pin dimensions, indentation depth, and the wall thickness of the plastic part also affects the durability of the overall connection structure. crimp contact female If the matching with the plastic part is poor, loosening, stress concentration, or fatigue failure may occur during assembly or use.
