NAK80 Plastic Mold Steel Properties
NAK80; the high performance plastic mold steel that revolutionized the plastics industry!
NAK80 is a pre-hardened steel with exceptional hardness, wear resistance and toughness. It has very high polishability. Its excellent dimensional stability and ability to maintain its shape and form under high stress and pressure levels make it the ideal choice for high precision plastic molding applications.
Whether you produce automotive parts, electronic components or medical devices, NAK80 delivers consistent, high-quality results. It is widely used in the production of molds, cores and fixtures, as well as other parts that require high wear resistance, such as screws and ejector pins.
This pre-hardened steel is hardened to an optimum hardness of 37-43 HRC, which provides exceptional toughness and dimensional stability.
NAK80 is easy to machine and with the right tools and cutting speeds you can achieve a high quality finish on machined parts.
Using NAK80 is a smart choice for any business that requires high precision plastic molding. It is a reliable and versatile material that delivers the consistent results required to meet the demands of modern manufacturing.
Choose NAK80 for your next plastic mold steel project and experience the difference for yourself. Contact us to learn more about how NAK80 can benefit your business!
