molding process parameters must be set according to different products
the growth rate of molding technology parameter setti is 10.6 percentage points higher than that of industries above the city. Ng differences depending on type of product
section 2 molding parameter setting
according to the molding steps, it can be divided into four processes: mold unlocking, heating, injection and ejection
Molding steps: mold opening/closing, heating injection and knocking out.
