Thermosetting polymers are the primary candidates for this method, as they undergo irreversible curing. Furthermore, it generates minimal waste since the flash—the excess material that escapes the cavity—is usually recyclable back into the granulate form.
Essential Considerations for Tooling Design in Plastic Compression Moulding
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. Unlike thermoplastic processes, the material remains in a solid state initially, relying on heat to soften it and pressure to ensure complete filling.
The mould then closes under pressure, forcing the material to flow and conform to the tool geometry. 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.
Essential Considerations for Tooling Design in Plastic Compression Moulding
Advantages Over Competing Technologies One of the primary advantages of this moulding technique is its ability to produce large, thick-walled parts without the warpage often associated with injection moulding. Industrial Applications and Sector Relevance This manufacturing method is a backbone of several high-demand industries.
