Notes in large injection molding process

First, large Plastic Injection Molding processing in the production, must be produced after a period of time in gradually improve the feed tube temperature, mainly because of just powered on the melt injection molding machine material tube with heating time is long, low melt viscosity, good fluidity, the product easy to run front, production after a period of time due to the melt constantly take heat away, cause insufficient melt, viscosity, liquidity is poor, make the products lack of glue.
Second, use three points into the glue so that the product into the glue evenly, to prevent the production of oval. When remanufacturing metal inserts, preheat the inserts to prevent cracking of the inserts.
Third, for the brittle phenomenon of products, increase the proportion of new materials and reduce the number of times to solve it, generally no more than three times.
