Rework risk
Fabrication Details That Commonly Turn Into Assembly Rework
The drawing can be correct while manufacturing variation in bends, welds, hardware or finishing still creates problems at final assembly.
01
Bend, Hole & Interface Alignment
Bends, holes, slots and mounting features need to stay related to the parts they connect to.
02
Weld Distortion & Geometry
Joined parts need controlled geometry so doors, panels, brackets and mating components still fit after welding.
03
Hardware & Assembly Fit
PEM hardware, studs, hinges and purchased components must stay in drawing-defined positions.
04
Finish, Masking & Surface Protection
Coating thickness, masked areas, visible surfaces and packing requirements need to follow the approved product requirements.
Project route
From Your Drawings to Repeatable Production
A simple project route keeps manufacturability, sample approval and repeat production tied to the same requirements.
01
Review the Drawings
Confirm material, thickness, quantity, key dimensions, hardware, finish and assembly requirements.
02
Check DFM & Quote Risks
Flag unclear tolerances, bend conditions, welding risks, hardware positions and finish-related issues before production.
03
Approve the Sample
Use the approved sample and confirmed requirements as the reference for repeat production where applicable.
04
Produce, Inspect & Protect
Check critical dimensions, fit and finish, then protect finished parts for packing and shipment.

Before the RFQ
Questions Buyers Usually Need to Confirm
Can you support prototypes and low-volume OEM orders?
What drawing formats do you accept?
Can you work from a physical sample if the drawing is incomplete?
Can you manufacture multiple related parts for the same product or assembly?
Can you install PEM hardware, hinges, handles or purchased components?
How do you move from prototype to repeat production?
