Since it is car lamp holder, need assembly with other products, that requests, the car lamp holder cannot deform after injection molding or it will have an impact on subsequent product assembly. Also the light reflection angle.

Second, the surface roughness is another important point for this injection molding parts, so the external surface of the mold we do is mirror polishing, after injection molding, the lamp holder need plating or painting sliver, silver plays the role of light emission. The light emission has the standard of the professional auto industry, so the mold tolerance we’ve done is within +/-0.02mm.

We sum up experience from small batch production, and produce a standard SOP operation process.

That’s why before mold start progress our engineer team usually will provide a Design For Manufacturing file for customer to confirm. After this stage, that is the really start for a mold production.

Design for Manufacturing or Design for Manufacturability (DFM) is the optimization of a part, product, or component’s design, to create it cheaper and more easily. DFM involves efficiently designing or engineering an object, generally during the product design stage, when it is easier and less expensive to do so, to reduce manufacturing costs. This allows a manufacturer to identify and prevent mistakes or discrepancies.
