Therefore, the mold temperature must be able to accurately control the process. If possible, the mold temperature should be higher. Holding time and molding cycle: In the case of satisfying the filling of the product without generating depressions or bubbles; Should be as short as possible to minimize the residence time of the melt in the barrel Other problems in the open mold injection molding process, in order to prevent the deterioration of the surface quality, Generally use less mold release agent for injection molding , when using recycled materials no more than 20%. For products other than pet, the product should be post-treated to eliminate internal stress, and pmma should be dried in 70-80t hot air for 4 hours; Pc should be heated 110-135 ° C in clean air, glycerin, liquid paraffin, etc., depending on the product, the maximum time is more than 10 hours. And pet must undergo a biaxial stretching process in order to obtain good mechanical properties. For precision grinding of precision molds with a dimensional tolerance of 0.01 mm or less, pay attention to the influence of ambient temperature, Constant temperature grinding is required. It can be seen from the calculation that the steel with 300mm length has a temperature difference of about 10.8μm when the temperature difference is 3°C (10.8=1.2×3×3,1.2μm/°C per 100mm deformation) , Every finishing process needs to fully consider the impact of this factor.
