NAK80 Mold Steel for High Quality Injection Molds
NAK80 is one of the world’s most widely used pre hardened mold steels for plastic injection molding. Known for its excellent machinability, superior polishability, stable hardness and EDM performance, NAK80 is an ideal choice for mirror finish molds, textured cavities and precision plastic components. Manufyn manufactures precision NAK80 molds through India’s trusted tooling partners for customers across North America and Europe.
What is NAK80 Mold Steel?
NAK80 is a premium pre hardened plastic mold steel developed for manufacturing high precision injection molds. Unlike conventional tool steels that require heat treatment after machining, NAK80 is supplied in a pre hardened condition, allowing faster machining, excellent dimensional stability and shorter tooling lead times.
The material is widely selected for molds requiring outstanding surface finish, EDM performance and complex cavity machining. It is especially suitable for transparent plastic parts, cosmetic products, consumer electronics, automotive interiors and medical components where mold quality directly affects the finished product.
At Manufyn, we manufacture precision injection molds using NAK80 through our network of qualified tooling partners equipped with advanced CNC machining, EDM, wire cutting, grinding and CMM inspection facilities. Our engineering team also supports customers with Design for Manufacturing (DFM), mold optimization and production planning to reduce overall project costs.
Why Engineers Choose NAK80
- Pre Hardened: Eliminates additional heat treatment after machining.
- Excellent Polishability: Suitable for mirror finish mold cavities.
- Superior EDM Performance: Reduced cracking and improved machining quality.
- High Dimensional Stability: Consistent mold accuracy throughout production.
- Good Texturing Ability: Ideal for cosmetic and decorative plastic products.
