About Extrusion Dies
Extrusion dies are the shaped tools through which heated billet is forced under pressure to produce a continuous profile of constant cross-section, in aluminium, plastics, or rubber. In aluminium extrusion, the steel die defines the profile and controls metal flow through bearings and feeder plates; in plastics and rubber extrusion, the die shapes the melt into pipe, sheet, profile, or film. They are fundamental tooling for architectural, automotive, electrical, and industrial profiles.
Aluminium extrusion dies are machined from hot-work tool steel, almost always H13, typically hardened to around HRC 45-52 and gas-nitrided to a high surface hardness (approaching 1000-1100 HV) because the bearing surfaces are washed by aluminium near 480-540 C; deep, well-controlled nitrided cases markedly extend die life, which otherwise fails by bearing wash and wear. Solid, hollow (porthole/bridge), and semi-hollow die types are used per the profile. Plastic and rubber extrusion dies are typically tool or stainless steel, often hard-chromed, with adjustable lips and flow channels.
Materials and treatments are matched to the extruded medium and temperature; nitriding cycles are tuned to balance hardness and case adhesion.
Configuration covers single- and multi-hole dies, feeder and backer plates, and correction/nitriding cycles over die life, with first-article profile verification.
Himalay coordinates material traceability via EN 10204 3.1 certificates for the die steel where requested, hardness and nitriding reports, dimensional and profile reports, and CE/RoHS support where the profile enters a regulated product, all coordinated as part of the standard order flow.
