Compression moulding uses heat and pressure to form the product’s final shape. This method employs a heated cavity and vertical press mechanism to effectively construct and maintain the required tooling.
Compression moulding wastes less material than injection moulding, as no runners, sprue, or gates are required to form the part. Consequently, this technique produces an aesthetically and functionally superior surface finish. This makes it the go-to technique for large flat and curved components.
The simplicity of compression moulding machines and low tooling costs make the process an attractive option for functional prototyping and low-volume manufacturing. In addition, compression moulding is the best option for when the part material used is impossible to produce using other moulding techniques and custom composites are fabricated.
Compression Moulding Applications
Electronics
This process is often used to manufacture switches, faceplates and electrical sockets.
Medicine & Dental
Many plastic and silicone parts used in the medical industry, such as respirator masks and syringe stoppers, are compression moulded.
Consumer Goods
Silicone is also used in a wide range range of consumer products, such as cookware, phone cases and bathroom accessories.
