Compression moulding process used to mould Dough Moulding Compound (DMC)

Materials used for compression moulding are either in the form of a dough-like substance or in sheet form.  Both forms are composed of resin, chopped glass fibres, a catalyst and a release agent. 

The dough like substance is called Dough Moulding Compound (DMC). 

A measured amount of Dough Moulding Compound (DMC) is placed into the heated female mould, (the yoke). The heated male side of the mould (the plug) closes forcing the Dough Moulding Compound into the mould cavities. 

 

The heat from the mould cures and hardens the compound. When the DMC has cured and hardened sufficiently, the plastic moulded product is ejected from the mould.

A more detailed description of the compression moulding process using dough moulding compound is in our new Plastics Module.

Learn about Plastics

We use animations and supporting technology notes to describe plastics and plastics processes.

Animations illustrate plastics processes in probably the most clear way possible, making plastics processes easy to understand, easy to learn and easy to remember.

Our plastics technology notes and animations describe all the major processes including:

Plastics Module

Our new Plastics Module developed from the work in the KS3 and KS4 D&T packages. It is a complete package that includes:

  • plastics technology notes
  • animations of plastics processes
  • a range of exercises that include design and make assignments (DMAs), focused practical tasks (FPTs) and technology questions.

To make teaching easier, the technology theory notes and exercises are in digital format, making them suitable for computers and whiteboards; and in PDF format, which makes it simple to print and duplicate A4 theory notes and worksheets.
