The Growing Industry Of Composite Manufacturing Process

What Is Composite Manufacturing?

Composite materials are those which are made up of two or more different materials which when combined become stronger than the individual materials. The components in a composite material don’t blend entirely or lose their individuality but combine and contribute their most useful traits to make the product.

The process of fabricating composite materials is known as Composite manufacturing. Typically constructed composite materials include reinforced plastics such as the fibre-reinforced polymer which is otherwise known as fibreglass and composite wood such as plywood.


There are mainly three types of composite manufacturing processes. These are listed below:

  1. Open moulding:

In this process, composite materials like resins and fibres are placed in an open mould and they take the definite shape while being exposed to air. Being a method involving inexpensive tooling Open Molding is often used for making prototypes and short production runs.

  1. Closed Molding:

In this process, composite materials are processed in a two-sided mould or a vacuum bag. Closed moulding can be used if enhanced production volumes are required, or a two-sided finish is needed. Its industrial applications are generally widespread, and it is one of the most widely used moulding methods.

  1. Cast Polymer Molding:

This can include both open as well a closed moulding method.  In this process, a mixture of resin and fillers are poured into a mould and then left to harden and take a definite shape.
