Core Manufacturing FAQ
What core types can you manufacture?
We manufacture mould cores for plastic injection and compression moulding (creating holes and internal features in parts), die cores for metal forming, tool cores for cutting tools, process cores for manufacturing equipment, and modular core inserts for scalable production.
What materials are best for high-wear cores?
Tool steel H13 is the industry standard for injection mould cores — excellent wear resistance and thermal fatigue resistance. P20 is popular for prototypes. For extreme wear applications, hardened stainless steel 420 or 17-4 PH are used.
What tolerances can you hold on core dimensions?
CNC machined cores hold dimensional tolerances of ±0.02mm on general features and ±0.01mm on critical mould release surfaces. Core geometry is verified with CMM and matched to part drawing specifications.
What is the typical lead time for custom cores?
Simple cores: 3–4 weeks. Complex multi-core assemblies: 4–6 weeks. Hardened and tempered cores: 6–8 weeks. Lead times include all machining, heat treatment, and finish grinding.
Can you achieve the surface finish required for mould release?
Yes. Cores are finish-ground to achieve precise surface finishes — typically Ra 0.4–0.8µm for plastic injection. Polishing can achieve mirror finishes for high-precision parts.
Do you offer heat treatment for core steels?
Yes. We manage hardening, tempering, and stress relief as part of our service. H13 cores are typically heat treated to 38–42 HRC. Heat treatment with dimensional stability verification available.
