The upper half of the mould, known as the male, descends to meet the lower half, the female, squeezing the material into every corner. Thermosetting polymers are the primary candidates for this method, as they undergo irreversible curing.
Engineering Design Compression Moulding: Principles and Process
Unlike thermoplastic processes, the material remains in a solid state initially, relying on heat to soften it and pressure to ensure complete filling. The selection of a compound dictates the required temperature, pressure, and cycle time, making it a critical variable in the engineering phase.
Additionally, the design of the parting line can be challenging, as the pressure flow tends to push material towards the path of least resistance, sometimes resulting in flash that must be trimmed. Material Science and Compound Types The success of plastic compression moulding hinges heavily on the specific compound used.

Furthermore, it generates minimal waste since the flash—the excess material that escapes the cavity—is usually recyclable back into the granulate form. Industrial Applications and Sector Relevance This manufacturing method is a backbone of several high-demand industries.
