Injection Mold for Single Parting Surface
When opening the die, the moving die and the fixed die are separated, so that the plastic parts are taken out, called single parting surface die, also known as double plate die (two plate die). It is the simplest and most basic form of injection moulds. It can be designed into single cavity injection moulds or multi-cavity injection moulds according to needs. It is the most widely used injection moulds.

Injection Mold with Double Parting Surface
Double parting surface injection mold has two parting surfaces. Compared with single parting surface injection mold, double parting surface injection mold adds a partially movable middle plate (also known as movable gate plate, which has gate, runner and other parts and components needed for die setting), so it is also called three-plate injection mold (movable template, middle plate, fixed template), which is often used for points. When opening a single or multiple cavity injection mould with gate feed, the middle plate is separated from the fixed template at a fixed distance on the guide pillar of the mould, so that the pouring system condensate can be removed between the two templates. The injection mould with double parting surface has complex structure, high manufacturing cost and difficult parts processing. It is generally not used for the forming of large or super large plastic products.
