Plastics
We work with manufacturers of molds and tooling for injection, blow molding, extrusion and thermoforming of plastics, a sector where precision, polish and material stability directly define the quality of the final part. Producing cavities, cores, inserts, plates and mold bases requires steels with excellent machinability, good polishability, high wear resistance and, in many cases, corrosion resistance. At NAT MAC we offer mold steels, pre-hardened grades, tool-grade steels and stainless steels, in the sizes the project needs. We complement them with facing and grinding, cut-to-size services and technical advice to choose the steel that best balances machinability, hardness, polish and tooling life, helping the mold last longer and produce consistent parts.
