Sheet metal fabrication

Custom Sheet Metal Fabrication for OEM Enclosures and Parts

Send drawings or STEP files for fabrication review before production. HARVLAND checks material, thickness, bend risk, hardware, finishing and inspection needs so your quote reflects the real manufacturing route.

Buyer Starting Point

Turn drawings into a clear fabrication route

Most sheet metal projects arrive as drawings, STEP files or sample photos. The first job is to identify the manufacturing route before cost, lead time or quality expectations are locked in.

  • Review laser cutting, punching, press brake bending, riveting, welding and assembly needs from one drawing package.
  • Confirm material grade, thickness, bend direction, bend relief, hole spacing and cosmetic surfaces.
  • Use the RFQ to surface risks that can change price, lead time, sample route or finishing method.

DFM Review02

Catch bend, fit and finish issues before production

Good fabrication review protects the buyer from avoidable rework. The review looks for fit problems, tolerance pressure and finish conflicts before parts are cut or bent.

  • Check bend radius, flange length, cutout location, insert clearance, weld access and assembly fit.
  • Plan coating or plating thickness where finish can affect grounding, sliding covers or mating parts.
  • Flag critical dimensions, cosmetic faces and packaging needs before quote assumptions become hidden.
Production Fit03

Support both simple parts and multi-process sheet metal work

A single project may include flat panels, bent chassis parts, stamped brackets, PEM inserts, welded details, surface finishing and protected packaging. These operations can be reviewed together as one manufacturing scope.

  • Custom enclosures, chassis, brackets, panels, covers, shields and equipment housings can be reviewed.
  • Material options include steel, stainless steel, aluminum, galvanized sheet, copper and project-specific metals.
  • Fabrication can connect with stamping, tooling, finishing and inspection when the product uses multiple metal parts.
RFQ Inputs04

Send the details that make quoting faster

A fabrication quote becomes more useful when the drawing package explains both geometry and product intent. That helps engineering return a route instead of a long list of follow-up questions.

  • Attach 2D drawings, STEP/STP files, DXF/DWG flats, photos or samples when available.
  • State material, sheet thickness, finish, color, tolerance, target quantity and delivery stage.
  • Call out inserts, welding, tapping, assembly, packaging, appearance and inspection requirements.
Buyer questions

Common buyer questions

Have a question about your part? Leave a message and a reply email.

What drawings are needed for sheet metal fabrication review?

2D drawings, STEP/STP files, DXF/DWG profiles, material, thickness, finish, tolerance, assembly notes and annual quantity help engineering review the route quickly.

Can fabrication include inserts, welding or assembly?

Yes. PEM inserts, riveting, tapping, welding, simple assembly and packaging can be reviewed when the drawing or assembly notes show the requirement.

Can surface finishing be included in the quote?

Yes. Powder coating, ink coating, plating, e-coating, anodizing, passivation, brushing, screen printing, pad printing and other finish requirements can be planned with cutting and bending so fit and appearance risks are clear.

How do I know whether my part should be fabricated or stamped?

The route depends on geometry, volume, tolerance and cost target. Low-volume panels or enclosures often fit fabrication, while repeat formed parts may need stamping tooling.

Guides and articles

Sheet metal process guideSheet Metal Fabrication Process: How We Take Your Drawing to Final InspectionAfter you send us a sheet metal drawing, three questions usually matter first: can the part be made as required, what is still missing for quotation, and what happens next? We review the drawing, model, material, hardware and finish requirements, then return one consolidated list of questions. Once we agree what the quotation and production will follow, we prepare material and flat-pattern data, plan blanking, deburring, bending, press-in hardware, joining and simple assembly within the quoted scope, coordinate external surface finishing, and finally inspect and package the part to the drawing.Design guideSheet Metal Bending DFM Guide: K-Factor, Bend Radius and Hole-to-Bend DistanceA reliable flat pattern depends on more than a CAD bend command. Use this guide to define the neutral axis, radius, flange and feature clearances for press-brake parts, then confirm the real bend data with the fabricator before release.Design guideHow to Design Custom Metal Brackets for ManufacturingDesign custom metal brackets around load paths, mounting datums, material behavior and the intended manufacturing route, then validate bends, holes, hardware, finish and formed tolerances before release.Cost and lead time guideCustom Sheet Metal Enclosure Cost Guide: What Drives Price and Lead TimeA custom enclosure price is the result of its material, geometry, process route, quantity, hardware, finish and approval requirements. Use this guide to understand quote differences and prepare an RFQ that gives suppliers a consistent basis for review.Process comparisonMetal Stamping vs Sheet Metal Fabrication for OEM PartsChoose a production route by the shape of your part, how much the design may change and the quantity you expect to buy. This guide shows how to compare stamping with laser cutting or punching plus bending, including the costs that a piece-price comparison can miss.RFQ guideSheet Metal Fabrication RFQ Checklist for OEM EnclosuresUse this sheet metal fabrication RFQ checklist to align enclosure drawings, materials, finishes, inspection notes and production expectations before quote review.
