Consumer Electronics Enclosure DFM
Rib sink, screw boss strength and visible parting line risk were reviewed before mold design approval.
Buyer situation
STEP files, cosmetic-zone notes and a target resin for a handheld enclosure with ribs, bosses and snap-fit details.
Main risk
Rib sink, screw boss strength and visible parting line risk were reviewed before mold design approval.
Engineering decision
Rib transitions, boss support and visible parting-line assumptions were reviewed before mold design approval so the buyer could choose between geometry edits and tooling complexity.
Sample gate
First samples would be checked for sink near ribs, screw boss strength, snap fit, visible parting line and gate mark location.
Evidence
DFM notes changed rib transitions and moved gate assumptions before mold steel.
Buyer takeaway
Enclosure projects need cosmetic surfaces and fastening features reviewed together; treating them separately often hides sink and assembly risk.
