Punching uses a CNC turret press to cut holes, slots, and shapes in sheet metal quickly, and can form louvers and embossed features. Choose punching for repeated features in medium to high volumes.
A range of materials is available, including Aluminum, Stainless Steel, Carbon & Cold-Rolled Steel, Galvanized Steel, Copper & Brass. The best choice depends on strength, appearance, operating environment, and budget. Our engineers can help you select the right one during the quote review.
Achievable tolerances depend on material, part size, and geometry. Typical values are listed on this page, and tighter tolerances can often be held on critical features. Share your drawing and we will confirm during the DFM review.
Yes. We support everything from a single prototype to ongoing production programs, so you can scale without changing supplier.
Cost depends on material, part size and complexity, quantity, tolerances, and finishing. Upload your CAD model and drawing to receive a quote, and our engineers can suggest design changes that reduce cost.
We accept common 3D CAD and 2D drawing formats, including STEP, STP, IGES, STL, SLDPRT, X_T, DXF, DWG, and PDF. If your format is not listed, please contact us.
Lead time depends on process, quantity, and finishing. Prototypes can often ship within a few business days, and we ship worldwide. Contact us with your requirements for a lead-time estimate.
Punching is typically faster and cheaper for standard shapes and larger volumes. Laser cutting is more flexible for complex contours and low volumes with no tooling.
