Built around your product, not a catalog size
Custom Chassis That Makes the Entire Product Easier to Build
We turn your CAD, interface map and performance requirements into a production-ready sheet metal chassis with controlled fit, clean assembly and repeatable quality.
Engineering before fabrication
Resolve chassis risk before metal reaches the laser
OEM engineers usually arrive with more than a box drawing. They have PCB keep-outs, connector windows, fan curves, service access, grounding paths and a target build time. Our five-engineer team reviews those relationships as one mechanical system.
Tolerance strategy
Critical-to-function dimensions separated from cost-driving cosmetic tolerances.
Airflow architecture
Vent patterns, fan mounts and internal obstructions reviewed together.
Grounding continuity
Masking, hardware and metal-to-metal contact planned into the finish.
Assembly access
Fastener direction and tool clearance designed for efficient builds.
A practical material system
Choose metal and finish by function
Aluminum
Low mass, thermal response and corrosion resistance for portable or high-value electronics.
5052 · 6061 · Anodized · Chem film
Cold-Rolled Steel
Stiff, economical construction for equipment frames, covers and production chassis.
CRS · Zinc plated · Powder coated
Stainless Steel
Cleanability and corrosion resistance for medical, food and demanding industrial use.
304 · 316L · Brushed · Passivated
One controlled path from drawing to shipment
Fewer supplier handoffs mean clearer accountability when dimensions, appearance and assembly all matter.
Review
CAD, drawing, BOM and application requirements.
Prototype
Laser cut, bend, weld and install hardware.
Validate
FAI dimensions, fit check and finish approval.
Scale
Fixtures and work instructions lock repeatability.
Deliver
Protected packing, reports and export support.

Chassis design guide
Chassis Design Checklist Before Fabrication
A useful custom chassis design review starts with the interfaces that cannot move. This checklist helps chassis engineering teams expose missing inputs before prototype metal is cut.
| Design input | What to define | Fabrication impact |
|---|---|---|
| PCB dimensions | Board outline, standoff pattern and keep-outs | Base size, datums and mounting accuracy |
| Connector locations | Port centers, plug envelope and cable bend | Cutout position and panel tolerance |
| Thermal sources | Heat load, airflow direction and hot zones | Vent, fan and baffle geometry |
| Grounding requirements | Bonding points and conductive interfaces | Hardware, masking and finish notes |
| Service access | Removal sequence and tool clearance | Cover splits and fastener direction |
| Future upgrade plans | Likely board, I/O or power changes | Modular panels and reusable brackets |
