When using the word ‘Tool’ in injection moulding production we are referring to the actual moulds used by the Injection Moulding Machines.
The tool is usually constructed from hardened steel, pre-hardened steel, aluminium, and/or beryllium-copper alloy. The use of these metals allows the molten plastic to be forced into every crevice and cavity, before solidifying and producing a precise and intricate end product.
Corona currently works with a tried and tested tool manufacturer in Portugal. We have been impressed at the quality of their product and their openness in allowing our staff to inspect their production line, when we have placed an order with them. However we at Corona keep abreast of other tool manufactures worldwide to ensure value for money is always a priority.
The choice of material to build a mould from is primarily one of economics; in general, steel moulds cost more to construct, but their longer lifespan will offset the higher initial cost over a higher number of parts made before wearing out. Pre-hardened steel moulds are less wear-resistant and are used for lower volume requirements or larger components.
As we have mentioned previously, Corona regularly contact other Toolmakers for costs and quality assurance, even visiting their factories, to ensure customer satisfaction – if Corona can make savings then we can pass them onto you, our customer.
The Corona team have flourished by making considered and informed economic choices. We evaluate surplus and discarded plastic for reuse, monitor the costs of running the machinery, ensure we have chosen well for our packaging suppliers and shop around for the best deals in courier services.
