Specialist Industries
Six sectors, six different definitions of done. We staff each project with people who know what your buyers audit.
Unlock Potential With the Right Metal
Aluminum or zinc decides weight, minimum wall, finishing options and cost before any tooling is cut.
Aluminum Alloys
A380, ADC12, A360, A413 and B390 — the five grades that cover most HPDC work.
- Lightest per unit strength
- Walls from 1.0 mm
- Best for thermal parts
Zinc Alloys
Zamak 3, 5, 2 and ZA-8 — chosen for thin walls, fine detail and plating quality.
- Walls down to 0.5 mm
- Sharpest as-cast detail
- Best plating finish
How to Work With Us
Three steps from a 3D file to a shipped production lot. No black boxes in between.
Share Your Design
Submit your 3D file (STEP, Parasolid, STL) and select your preferred process.
Get a Quote & DFM Feedback
We review the file, provide DFM recommendations and send a transparent quotation.
Production & Delivery
Parts pass in-process and final QC, then we pack to your requirement and ship.
