Plastic Molding Capabilities
Our basic guidelines for plastic injection molding include important design considerations to help improve part mold ability, enhance cosmetic appearance, and reduce overall production time.
Within a few hours after we receive 3D CAD models, we'll send you design for manufacturability (DFM) analysis and real-time pricing .Along with the pricing, our quote will also call out any difficult to manufacture features based on the manufacturing process you have selected. This can range from difficult to mold undercuts to deep holes on machined parts.
