Definition of Precision Cold Extrusion: Precision cold extrusion is an important part of precision plastic volume forming technology. Cold extrusion is to put the metal blank in the cold extrusion mold cavity at room temperature, The press machine will punch the blank by fixed mold to apply pressure to the blank so that the metal blank gets plastic deformation and be shaped into different part. Its precision is higher and the producing speed is faster.
Brass Cold Extrusion Part(Phone)
Brass Cold Extrusion Part(Phone) are customized from mobile phone industry and are non-sale items. These
These precision brass parts are formed by using continuous mold cold extrusion technology. The average output per minute can reach 300 pieces as maximum and the product tolerance can be controlled within ±0.02mm. Its product finish can be controlled within RA0.5 and the burring is preciously less than 0.01mm. We use brass wire to produce them and the material utilization rate is more than 65%. The efficiency of production rates is 50 times than CNC due to the advanced continuous mold cold extrusion technology, which can greatly reduce the cost of product utilization.
