Profile Design and Die Shop
Producing specific and custom profiles is our business — you imagine it, we manufacture it. Alongside our wide standard profile network (box, flat bar, tube, L, U, T, C, T-slot framing), we design and manufacture custom dies in-house.
Cross-Section Optimization and Die Flow Engineering
High-precision aluminium extrusion starts before cutting tool steel. Abrupt wall thickness transitions, deep narrow tongues and unbalanced metal flow can cause twist or surface streaks. Our engineers review every customer drawing to optimize extrudability while preserving functional geometry.
We engineer flat dies for solid/open profiles and multi-mandrel porthole dies for complex hollow and multi-chamber sections, using CNC machining and wire EDM to calibrate bearing lengths.
Die Nitriding, Maintenance and Dedicated Archiving
Following trial extrusion and dimensional sign-off, every die undergoes controlled nitriding and bearing polishing between runs. Approved dies are cataloged and stored in our climate-controlled die library exclusively for your repeat orders.

| Porthole (Hollow) Die | Mandrel + die cap with welding chamber | Tubes, multi-chamber facade and chassis profiles | EN 755-9 / EN 12020-2 |
| Accepted CAD Formats | 2D engineering drawings & 3D solid models | Fit-up, exposed surface and tolerance review | DWG, DXF, STEP, PDF |
| Tooling & Sample Lead Time | Die manufacturing + first trial press | Dimensional inspection and sample approval | 2–3 Weeks |
| Die Nitriding & Polishing | Periodic surface hardening and bearing care | Scratch-free extrusion ready for anodizing | DIN 17611 E0–E6 Ready |
FAQ
Can you reverse-engineer a profile from a physical sample if we do not have a CAD file?
Yes. We can measure your physical sample, generate a 2D/3D CAD drawing for your formal approval, and then manufacture the extrusion die.
Are custom customer dies kept confidential?
Yes. Custom dies developed for a client are archived under a dedicated customer code and are never used to supply third parties.
Which dimensional tolerance standards do you apply?
We manufacture according to EN 755-9 for general engineering profiles and EN 12020-2 for precision profiles in EN AW-6060 and EN AW-6063.
