Practical design review for this decision<\/h2>\n

Housing DFM starts with a functional wall map. Keep wall transitions deliberate, use ribs and bosses to carry defined loads, provide draft where the tool needs release, and consider how gate and ejection locations interact with cosmetic and dimensional surfaces. The supplier should review these decisions against the selected resin and tool layout.<\/p>\n

Record the assumptions on the drawing or RFQ so the supplier can confirm them before quoting. When a value is unknown, identify it as an open engineering item rather than copying a generic catalogue number that may not match the assembly.<\/p>\n<\/section>\n
