About Compression Moulds
Compression moulds are the heated steel tools used in compression moulding, where a measured charge of thermoset compound, rubber, or composite is placed in an open heated cavity and the mould is closed under pressure so the material flows, cures, and sets. The process suits thermoset plastics (phenolics, melamine, DMC/BMC), rubber, and fibre-reinforced composites, and is widely used for electrical insulators, switchgear parts, automotive under-hood components, seals, and SMC body panels.
Moulds are built from tool steels selected for the cure temperature and abrasiveness of the compound: pre-hardened P20 (around HRC 28-32) for general thermoset and rubber tools, and through-hardened H13 or stainless grades (HRC 48-52) for abrasive glass-filled SMC/BMC or corrosive rubber chemistries. Cavity count, flash-line design, and venting are set by charge weight and part geometry; heating is by electric cartridges or platen, with controlled cure cycles. Mould-base components can follow DME or HASCO standards.
Materials processed cover thermosets, elastomers, and composites; tool surfaces may be hard-chromed, nitrided, or PTFE-coated for release and wear.
Configuration covers flash, positive, and semi-positive mould types, multi-cavity layouts, and integrated ejection, with first-article and cure verification on the moulded part.
Himalay coordinates material traceability via EN 10204 3.1 certificates for the tool steel where requested, mould trial reports, dimensional reports on moulded samples, RoHS/REACH declarations, and CE support where the part enters a regulated assembly, all coordinated as part of the standard order flow.
