NAK80 Plastic Mould Steel

NAK80 Plastic Mould Steel

Product Overview 

NAK80 Plastic Mould Steel is a premium, precipitation-hardened plastic mould steel, renowned worldwide for its exceptional mirror-polishing capabilities and superior electrical discharge machining (EDM) performance. Delivered in a pre-hardened state (37-43 HRC), NAK80 Plastic Mould Steel eliminates the need for further heat treatment, ensuring remarkable dimensional stability. Its unique metallurgical structure provides a high-quality surface finish and uniform hardness throughout the entire block, making it the gold standard for high-precision, transparent, and high-gloss plastic products.
