Sheet Metal Fabrication in Action

Challenge

An electronics company needed a custom 1U server chassis in aluminum with complex ventilation patterns and precise locations for inserted hardware.

Solution & Result

We used laser cutting for the intricate vents, CNC bending for perfect angles, and automated hardware insertion for the PEM standoffs. We delivered 1,000 finished assemblies ready for the production line, saving the client significant assembly time.

Challenge

A manufacturer of industrial machinery required heavy-duty steel safety guards that were durable and highly visible.

Solution & Result

We fabricated the guards from 3mm thick steel sheet, using MIG welding for strong joints. A durable "safety yellow" powder coat finish provided both high visibility and long-term protection against wear and corrosion in a factory environment.

Challenge

A medical equipment company needed a sleek, easy-to-clean enclosure for a diagnostic device, made from 304 stainless steel with a premium look.

Solution & Result

We laser cut the components, used TIG welding for clean, non-porous seams, and then applied a #4 brushed finish with a specific grain direction. The final product was both aesthetically pleasing and met the hygienic standards of the medical industry.

Sheet Metal Fabrication FAQ

What is the difference between laser cutting and CNC punching?

Laser cutting is ideal for intricate contours, complex shapes, and cutting thicker materials with a smooth edge. CNC punching is extremely fast and cost-effective for parts with many standard-sized holes or simple shapes.

We can laser cut steel up to [e.g., 20mm], stainless steel up to [e.g., 15mm], and aluminum up to [e.g., 12mm]. Bending capabilities depend on the material and thickness. Please contact us with your specific needs.

Our standard tolerances for sheet metal features are typically ±0.2mm (±0.008″). Tighter tolerances are achievable but depend on the material, thickness, and geometry.

For a complete part, a STEP file is best. For flat patterns, a DXF or DWG file is ideal. Providing both is a great way to ensure accuracy.

Yes, absolutely. We have dedicated hardware insertion presses and can install a wide variety of self-clinching nuts, studs, and standoffs as part of our assembly service.

The bend radius is the inside radius of a bend. It’s important because bending metal too sharply can cause it to crack. Our standard inside bend radius is typically equal to the material thickness, but we can accommodate other requirements.
