          Hardware shrapnel production is a special process that involves cold stamping of materials (metal or non-metal) into parts (or semi-finished products) through stamping molds. Its types are complex and diverse, mainly divided into spiral metal shrapnel, scroll metal shrapnel, plate metal shrapnel, etc. according to shape, and can be further divided into plastic metal shrapnel, stainless steel metal shrapnel, copper metal shrapnel, iron metal shrapnel, aluminum stainless steel shrapnel, etc. according to material. And most of them are made of metal spring steel, which plays a high-quality switching role between products through the conductivity of metal spring.

          In the classification of hardware shrapnel, the widely used ones are battery shrapnel and mobile phone hardware shrapnel:

          1. Battery shrapnel: Battery shrapnel is a type of hardware shrapnel, mainly made of stainless steel shrapnel, copper shrapnel, and iron shrapnel. Due to its good conductivity and elasticity, copper is generally used.
