This product is a complex structure injection mold, suitable for producing plastic components with complex structures, difficult demolding, and strict dimensional requirements. According to product features such as undercuts, side holes, ribs, snap fits, deep cavities, and irregular surfaces, the mold can be designed with sliders, lifters, inserts, side core-pulling, hot runner, or cold runner systems. Proper mold flow analysis, parting design, cooling design, and ejection design help improve molding quality and reduce shrinkage, deformation, flash, and demolding defects. These molds are widely used for automotive parts, electronic housings, functional structures, medical device components, and industrial plastic parts.
