Electronics, control systems and instruments all need a box. For new products, quantities start small — which is exactly where a low volume sheet metal enclosure manufacturer adds value.
How Custom Enclosures Are Made
- Laser cutting of flat blanks
- CNC press-brake bending
- Insertion of PEM nuts, studs and standoffs
- Welding and grinding where needed
- Powder coating, plating or brushing
- Silk-screen printing or laser marking of labels
Material Options
| Material | Best for |
|---|---|
| Cold rolled steel (SPCC) | Cost-effective indoor enclosures, powder coated |
| Galvanized steel (SGCC) | Industrial cabinets, light corrosion protection |
| Aluminum 5052 | Lightweight, portable devices, anodized |
| Stainless steel 304 | Food, medical-lab and outdoor equipment |
Design Tips That Reduce Cost
- Use one sheet thickness per enclosure where possible.
- Keep a consistent bend radius.
- Place holes at least 2× thickness from bend lines.
- Use self-clinching hardware instead of welded nuts.
- Design lids and bases to share fasteners and hardware.
Prototype to Production
Laser cutting and bending need no dies, so prototype enclosures cost little more per piece than small batches. Once designs freeze, stamping can be considered for very high volumes.

FAQ
What is the minimum order for custom sheet metal enclosures?
Prototype quantities from one piece are possible because no tooling is required.
Which finish is most common for steel enclosures?
Powder coating, available in many RAL colors and textures.
Can you add printed labels to enclosures?
Yes. Silk-screen printing and laser marking are available.
