Compression molding of plastic parts ejection: after processing mainly refers to the annealing treatment, its main role is to eliminate stress, improve the stability, reduce the deformation and cracking of plastic parts, further curing, so as to improve the electric properties and the mechanical properties of plastic parts.
  Annealing treatment should be based on the plastic material, shape, insert and determining the. Wall thickness and wall thickness difference and easy to deformation of the plastic parts with lower temperature and longer time is appropriate; complex shape, thin wall, large area of plastic parts, in order to prevent deformation, annealing treatment is best in the fixture on.
