What is the main reason for the poor resilience of hardware shrapnel?

Hardware shrapnel, as the name suggests, is a resilient metal piece, which usually needs to be assembled with other parts to connect and disconnect. Anxin Spring's years of precision shrapnel processing experience often fails to spring back when pressed. The following are the common reasons why the lower shrapnel does not rebound or the resilience is not enough: ①Overtravel: For example, when the shrapnel is pressed by hand, the stroke is uncontrollable, which causes the overtravel to be too high and destroys the expected stroke value of the shrapnel itself. ②Overpressure: Pressing with super-strong force, the pressure is uncontrollable, and the load may exceed the normal preset pressure value of the shrapnel, which may cause over-travel and cause the shrapnel to deform. In this case, a harder material needs to be replaced. ③Over-crushing ring: Shrapnel scratches caused by sharp objects or molds during punching, because many shrapnels need to be bent, such as poorly designed molds and cracks at the bends, which will also affect the elasticity of the shrapnel . . ④The contact is too large: the contact design is unreasonable, resulting in the contact not working well with the shrapnel, which affects the normal use of the shrapnel. ⑤ Imbalance in the contact surface of the shrapnel: the periphery of the shrapnel is unbalanced or there is no ventilation groove designed. ⑥ Poor contact: The gap between the silicone button and the PCB board is too small. Install the shrapnel reasonably and pay attention to reserve space for the shrapnel. The poor resilience of hardware shrapnel is mainly due to the above six reasons. Basically, it is from the three general directions of whether the model structure design is reasonable, whether the quality control of the shrapnel processing process is qualified, and whether the material selection of the hardware shrapnel is correct. Hardware, 15 years of ingenuity, focus on precision metal shrapnel stamping, silk-like precision + 16 strict quality inspections, and the concept of the result of your needs as the result of the work, let you choose, and choose to rest assured!
