Dies · mould · tooling
Pultrusion dies, designed with you and proven on a running line.
Every die starts with a design-for-manufacture review of your cross-section and ends with a trial pull on the factory's own line. Tube, rod, structural, deck and grating dies are cut in the factory's die shop: three gantry machining centers, ten high-speed CNC mills, EDM and wire-cut.
Tube and rod pultrusion dies
Dies and mandrels for hollow tubes from φ20 mm to φ186 mm and solid rods in single and multi-cavity layouts.
Profiles and specs
Structural profile pultrusion dies
Open-section and multi-web dies for structural shapes, walkway and grating components, deck boards and flat strip.
Profiles and specs
Custom pultrusion die
Dies for sections outside the standard families: window and door frames, shutters, ladder rails, radome profiles and dies for third-party machines.

From drawing to die
Five steps, each with something you approve or receive.
Steel is cut only after you approve the 3D model. The die ships only after a trial pull and dimensional report.
- 01
Cross-section review
Buyer + die engineer
You send the drawing, resin system and target speed. The team checks wall thickness, radii and corners for pultrudability.
- 02
DFM feedback
Die engineer
Written feedback on changes that improve cure, fiber placement and die life, with the proposed fiber layout.
- 03
3D model approval
Buyer approval
Die plates, mandrel, heating layout and guide plates are modeled. Steel is cut only after you approve.
- 04
Machining and chrome
Die shop
Gantry milling, CNC, EDM and wire-cut, heat treatment, polishing and hard chrome plating.
- 05
Trial pull and report
Factory QC
The die runs on the factory's own line. You receive samples and a dimensional report before shipment.

FAQ
Pultrusion die basics
- What is a pultrusion die?
- A pultrusion die is a heated, chrome-plated steel cavity through which resin-impregnated fiber is pulled. The resin gels and cures inside the die, so the die sets the profile's dimensions, surface and much of its quality.
- Is a pultrusion die the same as a fiberglass mold?
- No. A hand-layup or RTM mold forms one part at a time. A pultrusion die is a continuous-process tool that runs under heat and pull force for thousands of meters. This page covers pultrusion dies only.
- Can you build dies for a machine you did not supply?
- Yes. Send the die table size, heating-plate layout and clamping method of your machine with the profile drawing.
- How long does a die last?
- Die life depends on steel, chrome thickness, filler content and line speed. Wear starts at the die entry; re-chroming before the steel itself wears extends life. The factory states an expected life per die rather than a generic figure.
