In the breakdown of production costs for a mould, how much does it cost to polish a cavity for optics? What about repairing that same cavity if polishing defects are detected? And how many days does the repair take?
In an industry where time is money, the quality of the raw material has a major impact on the final product, as does the manufacturing process (type of furnaces, consumables, production processes, etc.). To obtain the desired result and avoid repairs or polishing defects, especially in the final stage of mould production, it is essential to select tool steel from a reliable supplier of proven quality.
