Sample & Test
We produce prototypes or small trial batches for your validation before full-scale production.
Mass Production & Delivery
Extrusion → CNC machining → Anodizing → QC → Packing. On-time delivery to your door.
Why OEMs Choose Us
Five things you can check before the first order.
One network, open to your audit
Extrusion runs on presses up to 5,000 t, then our own CNC workshop, then anodizing. Every stage is open to your audit, and we go with you.
See how the extrusion stage works →CNC machining holds ±0.05 mm
We hold ±0.05 mm on bolt holes, locating faces and the lid sealing face. Extruded dimensions follow the tolerance class named on your drawing.
Read what the drawing should say →Walls from 0.8 mm, sections to 350 mm
Sections run from 40 mm to 350 mm across, with wall thickness from 0.8 mm to 6 mm. A wider section needs a thicker wall, and we say where the limit sits before you commit to a die.
Check the wall thickness limit →Blasting, anodizing, hardcoat
Sandblasted and anodized as our standard finish. Type III hardcoat is available to your drawing.
See what anodizing changes →A finished sample in about 25 days
About 25 days from your drawing on average: 15 for a new die, three for extrusion, one for anodizing. Wide sections and thin walls commonly need one rework, and each rework adds 5 days.
See what a quotation needs →One accountable partner
Extrusion, CNC machining and anodizing come to you as one integrated production network, so one drawing, one quote and one party answer for the result.
