Compression molding is a process of molding in which a feeding material is placed into an open, heated mold cavity. The mold is then closed with a top plug and compressed with large hydraulic presses in order to have the material contact all areas of the mold. The charge cures in the heated mold.
What are the steps of compression moulding?
The process of compression moulding begins with:
The material is placed into the mould.
The product is heated until somewhat soft and pliable.
A hydraulic tool presses the material against the mould.
Once the material is hardened and has taken shape of the mould it is ejected.
What is the advantage of compression moulding?
The advantages of compression molding are three-fold: Low cost - Due to its simplicity, compression molding is very cost-effective when compared to other techniques. Little waste - Little material is lost during the molding process.

Electrical components.
Automotive parts.
Other various polymer matrix composite part
What compression molding is mostly used?
Thermoset composites
Thermoset composites are the most common type of material used in the compression molding process. Thermosets include Bakelite, polyester, polyurethane, urea-formaldehyde, as well as melamine, epoxy, and alkyd resins. Thermoset materials are selected based on their properties, the application, and the associated costs.
What are the different types of compression mould?
There are three types of moulds for compression molding. They are flash moulds, positive moulds and semi-positive moulds. The flash mold has a simple structure and low manufacturing cost.
Transfer molding is different from compression molding in that the mold is enclosed rather than open to the fill plunger resulting in higher dimensional tolerances and less environmental impact. Compared to injection molding, transfer molding uses higher pressures to uniformly fill the mold cavity.
