Design for manufacturing
Bend radius vs. thickness
Match the inside bend radius to material, temper and sheet thickness to reduce cracking risk.
Hole-to-edge distance
Keep holes and slots clear of bend lines and edges based on the selected process.
Relief cuts at bends
Add practical bend relief where adjacent edges may tear, distort or retain stress.
Consistent gauge per part
Design each component around one sheet thickness unless a joined assembly is intended.

FAQ
Common questions
What is the minimum order quantity?
Prototype and production quantities can be reviewed. Practical minimums depend on material, setup, finishing and purchasing requirements.
Can you weld dissimilar metals?
Dissimilar-metal joints require material and application review; mechanical fastening or an alternate joining method may be recommended.
Do you provide hardware insertion?
PEM nuts, studs, standoffs and related hardware insertion can be reviewed as part of the fabricated assembly.
