Product Description

Multi-Cavity Aluminum Extrusion Die – High-Efficiency Tooling for Mass Production

EPS designs and manufactures multi-cavity aluminum extrusion dies to significantly increase your extrusion output per press stroke. By producing multiple identical profiles simultaneously, our multi‑hole extrusion dies reduce production time, lower energy consumption, and improve overall cost efficiency. Available with up to 20 cavities depending on profile size and press tonnage.

Each multi‑cavity die is machined from premium H13 hot‑work tool steel, vacuum heat treated to HRC 48‑52, with optional nitriding for extended die life. We use advanced CAD/CAM simulation to balance material flow across all cavities, ensuring consistent dimensions and mechanical properties for every extruded profile.

Why Choose a Multi-Cavity Extrusion Die?

Higher productivity – Produce 2 to 20 profiles per press stroke. Significantly increases output per hour.
Lower per‑unit tooling cost – One die does the work of multiple single‑cavity dies.
Consistent quality across cavities – Our flow simulation ensures even metal distribution, minimizing dimensional variation.
Energy efficient – Extrude more profiles with the same billet heat and press energy.
Custom cavity layouts – We design linear, radial, or staggered patterns to fit your extruder and cooling table.

Multi-Cavity Configurations We Offer

2‑cavity die – Ideal for medium to large profiles (e.g., handrails, curtain wall mullions).
4‑cavity to 6‑cavity die – Common for smaller profiles like heat sinks, LED housings, and trim.
8‑cavity to 12‑cavity die – For very small profiles such as wire channels, spacers, and decorative trims.
Up to 20‑cavity die – Ultra‑high efficiency for miniature profiles (available upon engineering review).

We also produce multi‑port porthole dies for hollow multi‑cavity profiles, combining the benefits of hollow extrusion with multi‑cavity productivity.

Applications of Multi-Cavity Aluminum Extrusion Dies

Our high‑cavity tooling is widely used for mass‑produced aluminum profiles in:

Thermal management: heat sink profiles, LED cooling fins
Building & construction: window frame inserts, partition clips
Electronics: enclosure rails, connector housings
Automotive: trim strips, sealing bead carriers
Industrial: small conveyor components, sensor mounts
