Our Advantages
OEM/ODM tooling and product design based on your drawings.
High-precision aluminum extrusion for stable structural components.
Multi-axis CNC machining with tight tolerance processing.
Anodizing, sandblasting, brushing, and powder coating options.

Q: What is your machining tolerance?
A: We achieve ±0.01mm using 5-axis CNC, ensuring perfect alignment for your lens projector modules and optical components.
Q: How do you ensure internal rail smoothness?
A: Every unit passes CMM inspection. We offer 3D fitment simulation to guarantee zero-interference assembly for moving parts.
Q: Is it heat-resistant for high-power LEDs?
A: Yes. Made of automotive-grade aluminum, it withstands 120°C+ without deformation. Hard anodizing prevents surface oxidation.
Q: Do you offer rapid prototyping?
A: Yes. We can CNC-machine 1-50 units directly from aluminum blocks in 7-10 days, saving you mold costs during R&D.
Q: Is the housing waterproof?
A: The precision-milled interfaces ensure a perfect seal. Our parts are designed to meet IP67 / IP6K9K standards with standard gaskets.
