Clamping time refers to the time from when a mold is completely closed until when clamping force is pressurizing.
Clamping time does not change on one molding machine.
Closing time refers to the time from when a mold starts closing until when it is completely closed. Closing time varies depending on the movement amount or the shape (thickness) of a mold. A mold is closed at high speed at first, and then at low speed immediately before a slide core or an angular pin starts moving. Therefore, adjust closing time at the position where the speed changes or in the low speed zone. The shorter the closing time is, the shorter the molding cycle time can be; however, clamping must be done securely rather than shortening its time, because incomplete clamping will cause molding defects.
