Moulds FAQ
What mould types can you manufacture components for?
We manufacture custom mould components for injection moulding (cavities, cores, sliders, and inserts), blow moulding (parison tubes, pinch-off tools, and core pins), compression moulding (cavity plates and cores), rotational moulding (inner and outer shells), rubber moulding (cavity inserts), die casting mould inserts, and prototype moulds for testing. Each mould component is designed for your specific production process and material.
What materials are best for high-wear mould cavities?
Tool steel H13 is the industry standard for injection and compression mould cavities — excellent machinability, good heat transfer, and proven long production runs. P20 is used for rapid prototyping and short-run moulds due to lower cost and easier machining. S7 is specified for high-stress moulds and impact applications. Stainless steel 420 provides corrosion resistance for medical and food applications. Beryllium copper is used for high-speed moulding due to exceptional heat transfer. Each material choice depends on production volume, cooling requirements, and corrosion environment.
Can you achieve the surface finish required for mould release?
Yes. We polish and finish mould cavities to the surface finish you specify — typical injection mould cavities require Ra 0.4–0.8µm for automatic release, while cosmetic parts may need Ra 0.2µm or better. Our polishing process includes machine polishing, hand finishing, and inspection to confirm release angle and surface quality. Mould release coating (DLC, nitriding, or hard anodising) can also be applied for enhanced release and wear resistance.
What is the typical lead time for mould components?
Prototype mould components (P20, simple cavity) typically take 10–15 business days. Production mould cavities (H13, hardened, polished) take 20–30 business days depending on cavity complexity and number of cooling passages. Multi-cavity mould blocks or complex core pins may take 30–45 business days. Express scheduling is available for urgent projects.
Do you offer heat treatment for mould steels?
Yes. We arrange heat treatment for tool steels as part of the mould component supply — hardening to 38–45 HRC, stress relief, and cryogenic treatment are available. We work with established heat-treat partners to ensure dimensional stability and achieve your required hardness. All heat-treated components are delivered with hardness test reports and certified materials documentation.
Can you manufacture prototype moulds for testing?
Yes. Prototype moulds in P20 or aluminium 7075 can be delivered in 10–15 business days, allowing you to validate your design before committing to production tooling. Prototype moulds are cost-effective for proof-of-concept and pilot production runs. Once your design is validated, we can upgrade to production-grade tool steel (H13) for long-run production.
