Injection Compression Moulding
Precision Without Compromise
Injection Compression Moulding (ICM) is an advanced manufacturing process that combines the benefits of traditional injection moulding and compression moulding to produce highly precise plastic components with superior dimensional stability and surface quality.
Unlike conventional injection moulding, where the mould is fully closed before material injection, injection compression moulding begins with a partially open cavity. The molten plastic is first injected into the mould, followed by a controlled compression phase that closes the mould completely and distributes the material evenly throughout the component.
This controlled process reduces internal stresses, minimizes warpage, and delivers exceptional accuracy, making it particularly suitable for demanding applications where dimensional consistency is critical.
How the Process Works
Controlled Material Distribution
The mould cavity remains partially open during the initial injection stage, allowing material to flow more freely into the component geometry.
Compression Phase
Once the material is injected, the mould closes under controlled pressure, distributing the melt evenly throughout the cavity and forming the final component shape.
Optimized Cooling
The uniform material distribution and reduced stress levels allow the component to cool more consistently, resulting in enhanced dimensional stability and improved surface quality.
Why Choose Injection Compression Moulding?
