What core parameters should a high-quality injection molding machine have?

1、 Technical parameters of clamping parts

(1) Clamping force: lock the mold to overcome the maximum locking force of the melt expansion mold

(2) Forming area: refers to the maximum projection area of the clamping force under a certain pressure of the master die

(3) Opening force: the maximum force to open the mold to take out the product

(4) Open stroke: the maximum distance that the template can be moved to eject the product

(5) Template size: installation plane size of front and rear molds and mobile molds
