Dec 03, 2018 · In the molding process, plastic is injected into the mold at an exceptionally high-pressure rate, which creates a natural pull to force the mold open. A press is designed to keep the mold shut with larger parts requiring more tonnage and force, and smaller parts requiring less. A general calculation for determining press size needed is as follows:

PP plastic injection molding six points. ... so the effect also is not big. 2, screw PP processing is most are driven by the screw of liquidity, so the design of the screw influence is very big, diameter size affect the output, the compression ratio of the size influence pressure value also affect the output and the finished product effect ...

Compression molding and injection molding are very similar, but they have one major difference. In compression molding, molds are closed around the charge, and in injection molding, the charge is injected into a closed mold cavity. Today’s manufacturers frequently use both compression and injection molding but for different types of parts.

In injection molding, finding the right tonnage can be tricky. Just because a moulding machine can produce a clean looking part without flash it doesn’t mean the clamp is enough. For any particular part, there are a range of clamp tonnages than can produce parts that appear to be ok.
