Customized Hollow Aluminum Extrusion Die - Complex Profile Tooling Solutions

Custom Hollow Aluminum Extrusion Dies for Complex Profiles

EPS manufactures high‑precision custom hollow aluminum extrusion dies designed for complex profile applications across architectural, industrial, and automotive sectors. Our dies are machined from premium H13 hot‑work tool steel, heat‑treated to HRC 48‑52 hardness, with optional nitriding for extended service life.

Each die undergoes computer‑simulated flow manifold analysis to optimize aluminum flow distribution, reduce welding line defects, and minimize the need for costly corrections. Typical output exceeds 6 tons of aluminum profile per die under proper usage and maintenance.

Available in die diameters from 60mm to 1000mm, supporting wall thicknesses as low as 0.6mm (0.8‑1.8mm for most hollow profiles). We produce both bridge dies (spider dies) and porthole dies, as well as multi‑cavity designs up to 20 cavities.

Technical Specifications – Custom Aluminum Extrusion Tooling

Why Choose EPS for Your Hollow Aluminum Extrusion Die?

• Save on Tooling Costs – Competitive pricing compared to European/US suppliers, without compromising H13 steel quality or heat treatment standards.
• Fast & Reliable Delivery – 5‑day standard production (starting from drawing approval), 15 days to your port. Nitriding adds only 2 working days.
• Proven Performance – Many EPS dies require no correction, only minor polishing upon first trial. We provide free die correction recommendations and usage guidance.
• Test‑Before‑Pay Available – For trial orders, we can perform a test extrusion at our partner facility before you make final payment.

Hollow & Solid Extrusion Die Types We Manufacture

Whether you need a porthole die for multi‑hollow profiles or a bridge die for complex thin‑walled sections, EPS has the engineering capability.

• Porthole Die – Ideal for multi‑hollow profiles (2‑20 hollow chambers).
• Bridge Die / Spider Die – Suitable for larger hollow profiles or shapes requiring high strength.
• Flat Solid Die – For solid rods, bars, and simple shapes.
• Semi‑Hollow Die – For profiles with a partially open cavity.
• Multi‑Cavity Die – Up to 20 cavities, maximizing extrusion output per press stroke.

Applications – Where Our Custom Hollow Dies Excel

Our custom aluminum extrusion tooling is used to produce complex profiles for:

• Architectural systems: window & door frames, curtain walls, handrails
• Industrial profiles: conveyor rails, heat sinks, LED housings
• Renewable energy: solar panel frames, mounting structures
• Automotive components: bumpers, battery enclosures, trim profiles
• General engineering: custom hollow sections, pipe, and tubing
