Tab-and-slot design tips

Tab-and-slot design is a proven DFM strategy in sheet metal fabrication that improves assembly alignment, reduces tolerance stack-up, and minimizes the need for fixtures.

Hole-to-edge and hole-to-bend distance

Proper hole placement is a critical DFM factor in sheet metal fabrication. Holes placed too close to bends or edges can distort, crack, or shift during forming, causing assembly and cosmetic issues. This article outlines practical hole-to-bend and hole-to-edge guidelines and shows how early DFM adjustments improve yield and production stability.

Design for Manufacturability (DFM)

Design for Manufacturability (DFM) is a critical discipline in precision sheet metal fabrication, bridging the gap between CAD design and real-world manufacturing.

Powder Coating Process Flow at Rollyu Precision

Bead blasting is a gentle, non-destructive surface treatment widely used in precision sheet metal fabrication to achieve uniform matte finishes, improve coating adhesion, and remove micro-defects without altering part dimensions.
