It is generally based on Shrapnel The material of the shrapnel is determined by the use and performance of the shrapnel. For example, physical resilience is required. The frequency of use is relatively high and the pressure is large. Spring steel, carbon steel or high hardness stainless steel are generally used. After forming, heat treatment and quenching can reduce the carbon content and increase the pressing service life of the shrapnel by increasing the hardness.
In order to achieve the physical properties such as easy welding, acid and alkali resistance, increasing conductivity, etc, Using copper to process shrapnel, such as phosphor copper shrapnel, beryllium copper shrapnel. It can be achieved by electroplating (gold, silver, nickel, tin, etc.) and other surface treatment methods.

Mobile phone shrapnel is characterized by: conductive Shrapnel, because the use of different fields, so the shape is not the same, is the need to open die stamping. After the metal sheet is made into shrapnel by mould, it has physical resilience. If the frequency of use is higher, the pressure is larger. One side is spring steel, stainless steel. After forming, heat treatment and quenching can reduce the carbon content and increase the pressing service life of the shrapnel by increasing the hardness. If the use environment is special, electroplating treatment can be done in the process of shrapnel processing, so as to achieve physical properties such as easy welding, acid and alkali resistance, and increase conductivity. Such as mechanical shrapnel, mobile phone button shrapnel, battery shrapnel and so on.

For digital products such as electronic communication, The main process performance requirements are mainly reflected in accuracy, conductivity and weldability. So we use copper to process shrapnel products, The customers of Heju company usually specify the use of copper materials with fixed grade / hardness, such as phosphor copper, beryllium copper, red copper, brass, bronze, etc. If we need to use imported materials, we have long-term cooperation with famous Japanese copper manufacturer NGK. This kind of shrapnel is usually small. The consumption is large, so we use Japanese processing equipment to improve the efficiency of copper shrapnel processing under the condition of ensuring the accuracy. Such as riveted shrapnel, relay shrapnel, Mobile phone shrapnel etc. Characteristics. Anti interference electromagnetic wave overflow effect. Elastic and shock suppression function, can adjust the height to protect the effect of certain parts. Mobile phone shrapnel is easy to solder, can be directly welded to various motherboards.
