The Cold-press Needle Heats Up Rapidly Under Heavy Load.

In the industrial manufacturing sector, crimp contact exhibits a significant temperature rise under high-load operating conditions. This phenomenon stems from the interaction between mechanical work and frictional losses, directly impacting mold life and workpiece quality.

The cold pressing process is essentially a process that alters the microstructure of a material through mechanical pressure. When a heavy load is applied to crimp contact pin, the contact stress between the indenter and the workpiece surface increases rapidly. The microscopic peaks on the contact surface rub against each other, and the grains within the material undergo plastic deformation; all these processes release heat energy. The higher the unit pressure that contact socket crimp can withstand, the smaller the contact area, and the faster the heat accumulates.

crimp contact female The rate of temperature rise is positively correlated with the intensity of the heavy load. Under normal operating pressure, crimp contact male's surface temperature can rise from room temperature to 60-80°C within minutes. When the pressure exceeds the design limit, the temperature rise is even steeper. During this heat accumulation process, the temperature distribution varies at different locations within the indenter, with the highest temperature at the contact area, gradually decreasing towards the interior.
