Surface Finish and Material Properties The tooling surface in compression moulding directly transfers its texture to the final product, resulting in high-quality surface finishes that often require minimal post-processing. The cycle time is generally longer than that of injection moulding because the process relies on curing rather than rapid cooling.
Pressure Optimization Plastic Compression Moulding Techniques and Benefits
Unlike thermoplastic processes, the material remains in a solid state initially, relying on heat to soften it and pressure to ensure complete filling. Plastic compression moulding is a manufacturing process where a pre-measured charge of material, often in the form of granules or a sheet, is placed directly into a heated mould cavity.
Parts with intricate details, undercuts, and complex geometries can be achieved without the need for complex core pulls or side-actions required in other moulding processes. Design Flexibility and Part Complexity Engineers appreciate the design flexibility offered by plastic compression moulding.
Optimizing Pressure for Superior Compression Moulding Results
It allows for the integration of metal inserts during the loading stage, creating strong bonding that withstands thermal cycling. Labour costs can be higher since the process often requires manual loading of the material charge.
