With 28M+ parts manufactured, 450+ customers, rapid prototyping, engineering support, and quality control services, Metalcax helps unblock innovation from prototype to low-volume production.
What Is The Sheet Metal?
Sheet metal is a versatile cold-working process used to transform thin metal sheets, usually below 6 mm, into functional parts for prototyping, product development, and mass production. Through shearing, punching, cutting, folding, riveting, splicing, and forming, flat metal can be shaped into precise structures such as enclosures, brackets, panels, frames, and automotive components.
As applications grow, good part design becomes essential for engineers. A well-designed sheet metal component must balance function, appearance, manufacturability, strength, and cost. By optimizing bend radii, hole positions, material thickness, and assembly methods, manufacturers simplify tooling, improve efficiency, reduce waste, control costs, and deliver stable, high-quality metal parts for industrial use.

Frequently Asked Questions
Custom sheet metal parts services include the fabrication, welding, finishing, inspection, and packaging of metal parts made to customer drawings. Services may include laser cutting, bending, TIG/MIG welding, spot welding, riveting, hardware installation, deburring, surface finishing, and assembly.
Yes. We support TIG welded sheet metal assemblies for cleaner precision seams, MIG welded sheet metal frames for stronger structural parts, and spot welding for efficient sheet-to-sheet joining. Welding method selection depends on material, thickness, strength, appearance, and distortion control needs.
Distortion control starts with DFM review, weld sequencing, fixture design, heat input control, tack welding strategy, and inspection after welding. For critical parts, we recommend defined datums, tolerance zones, and functional inspection points on the drawing.
Yes. We can supply finished assemblies, sub-assembly packaging, and kitted components with labels, protective packing, and batch identification. This helps OEM buyers reduce receiving time, simplify line-side assembly, and improve production traceability.
