Punch Die Copper Sleeves are designed and used for punching mould, and it is put into the bushing, to make sure bushing work smoothly. Such design also makes the bushing free-oil. The die cooper sleeves are mainly processed by CNC machines, make sure the high quality and good precision. They are much better service for punching dies. We believe more and more customers will choose such sleeves to serve their dies.
Application Feature
1).Good load capacity and anti-wear.
2).It is in high load capacities and low speed with rotational, oscillating or frequent stop-start motion.
3).It can work for a long time without oil in the condition of boundary lubrication, under oil or grease lubrication interval, the working-life will be longer.
4).It is machining for the thicker of PTFE.
5).The bushes can be applied in auto chassis , forging machine, metallurgical, civil engineering ,power station, strip rolling industries, ect.
6).It is widely used in the machine where lead is unacceptable.
