SHEET METAL FABRICATION OVERVIEW

Built Around Your Fit, Finish and Assembly

Bring cutting, forming, welding and hardware into one reviewed route for your sheet metal parts and enclosures.

  • Reduce avoidable rework before cutting and bending.
  • Protect hole locations and mating dimensions after forming.
  • Plan self-clinching hardware and welding before coating.
  • Define your visible surfaces and finish acceptance.
  • Move your approved part into repeat production.

Frequently Asked Questions

What affects my sheet metal fabrication quote?

Material grade and thickness, flat size, cut features, bend count, welds, hardware, finish, quantity and inspection scope all affect your route and cost. Send a controlled drawing and CAD model so these requirements can be reviewed together.

Which tolerances can you achieve for my part?

Your achievable tolerance depends on geometry, material, thickness, process and measurement method. Mark critical dimensions and mating features. We confirm feasible requirements in your quotation rather than applying one blanket tolerance to every part.

Can you support prototypes and repeat production?

Share prototype, batch and annual quantities. We review a practical manufacturing route for your validation parts and discuss what needs to be confirmed before repeat production.

What files should I send with my RFQ?

Send a 3D CAD model, controlled 2D drawing, material and thickness, finish requirements, quantities and delivery destination. Include flat patterns when available, plus weld, hardware and critical-fit requirements.

Can you help with sheet metal DFM?

Yes. Your review can cover bend access, inside radii, flange lengths, hole-to-bend spacing, reliefs, welding and hardware installation. Agree any design changes before your drawing is released.

Can you finish and assemble my parts?

Discuss deburring, coating, plating or anodizing alongside your hardware, assembly and packaging needs. Finish compatibility, masked surfaces and inspection requirements are confirmed for your selected material.
