  Plastic mold dimensional accuracy is affected by factors such as mold manufacturing and assembly errors, mold wear. In addition, the design pressure of mold and injection mold, you should also consider forming machine and structural parameters of the matching process. In plastic mold design has been widely used computer-aided design technology.
 
 
  Plastic mold’s working conditions are different, the general must be 150 ° C-200 ° C under the work, except under certain pressure, but also withstand the temperature.
 
  Plastic mold plastics at work due to the filling and flow is subjected to greater stress and friction, requiring precision and the shape of the mold to maintain the stability of dimensional accuracy to ensure there is enough mold life.
 
  Plastic mold wear resistance depends on the chemical composition and heat treatment of steel hardness, thereby increasing the hardness of the mold will help improve the wear resistance.
