This professional DFM design guide explains all manufacturability design standards fully matched with our standardized OEM factory production system covering structural thickness control, mold demolding angle design, assembly gap tolerance, surface craft feasibility and raw material processing limitation requirements, brand designers need to adjust original product sketches and 3D models according to unified factory DFM rules before submitting formal customization demand to our engineering team, our OEM factory system will automatically generate DFM evaluation reports after receiving design files to mark unreasonable structural designs that will lead to difficult mold opening, high production defect rate or long processing cycles, all revised design versions will be archived in the customer exclusive file library of the factory digital system as the official production design benchmark after two-way confirmation between the brand and engineering department, following complete DFM design specifications can greatly reduce repeated mold modification, multiple sample iterations and mass production rework risks inside the whole OEM manufacturing system, shorten the overall custom product development cycle and stabilize the production cost budget for every cross-border brand’s OEM customization project.
