Frequently Asked Questions
What does custom sheet metal include?
Typically laser cut, bend, optional weld, hardware, and finish—scoped on the quote.
Can you match my powder color?
Yes within common RAL/custom ranges—confirm on RFQ.
PEM before or after coat?
Depends on hardware and finish—process planned on DFM.
IP / EMI ratings?
We fabricate to your design. Ratings require your validation—we do not overclaim chamber certifications.
MOQ?
Prototypes from 1 piece; production lots quoted with breaks.
Drawings needed?
STEP + 2D with CTQs preferred; DXF flats accepted.
Lead time?
Depends on weld/finish complexity—simple bent parts faster than coated weldments.
Certifications?
Soft capability language for industrial/commercial fab.
Custom sheet metal—service overview
Custom sheet metal combines cutting, forming, joining, hardware, and finishing into complete parts.
Choose this path when you need finished enclosures or brackets—not just flats.
Partsproto delivers from China with FA gates and export packaging.
- → Finished enclosures
- → Hardware-installed panels
- → Welded custom assemblies
- → Coated production kits
DFM tips for custom sheet metal
- •Provide complete BOM for hardware.
- •Call cosmetic class and grain.
- •Specify masking for ground points.
- •Design gasket grooves with clear dims.
- •Freeze revisions before coating color match.
Inspection & QC
- ✓Formed dims and hardware presence.
- ✓Coating appearance/adhesion notes.
- ✓Fit of lids/doors when assemblies ordered.
- ✓Packing inspection before freight.
Lead time & batch sizing
Prototype enclosures often need extra days for hardware and coat. Request 5 / 50 / 200 breaks and FA sample gate.
