How to put the sheet into the mold cavity in extrusion sheet

1, there are many ways, depending on the product structure to be set. PET sheet positioning in the injection mold has the following options:

(1), the use of product positioning within the hole

(2), the use of product shape positioning

(3), the mold to do pierced

(4), mold made of tiger teeth

2, Plastic injection molding process of extrusion sheet die includes clamping --- filling - packing - cooling - stripping and other five stages. Filling is the first step in the entire injection cycle, counting from the time the mold is closed until the mold cavity is filled to about 95%. In theory, the shorter the filling time, the higher the molding efficiency, but in practice, molding time or injection speed is subject to many conditions.1, there are many ways, depending on the product structure to be set.
