Can you quote without DXF or STEP?
A rough first screen can start from photos or PDF, but accurate pricing needs usable geometry and manufacturing notes. For formed parts, STEP plus PDF is usually stronger than a flat image alone.
FAQ
Sheet Metal Fabrication FAQ
Answers for buyers preparing custom sheet metal parts for quote and production review.
Questions
Prepare the information that makes a quote useful.
The FAQ is also a qualification page for RFQ readiness.
Do you support prototypes?
Yes, when the project has practical production intent. Prototype work is strongest when it is connected to fit validation, pilot production or repeat-order planning.
Can you suggest material alternatives?
Yes, if you share function, finish, strength, corrosion exposure and cost priorities. For example, 5052 aluminum may be a better forming choice than 6061 for many enclosure parts.
Can powder coating or anodizing be included?
Yes. Finish should be specified early because it affects masking, cosmetic review, lead time, thread protection and packing.
Can you provide inspection reports?
Yes when requested. The scope depends on critical dimensions, tolerance, coating requirements and buyer release needs. Common evidence includes photos, first article checks and dimensional reports.
Can files wait until NDA?
Yes. Send safe context first, such as part family, material, quantity, process route and target market, then share detailed CAD after fit and NDA discussion.
What information changes sheet metal cost the most?
Material grade, thickness, cut complexity, bend count, welding, PEM hardware, finish, inspection scope, packing and quantity tiers usually have the biggest impact.
What file package is best for enclosures?
A STEP model, a PDF drawing, flat DXF files when available, finish notes, hardware callouts and marked cosmetic faces create the clearest enclosure RFQ package.
