plastic injection molding

Injection molding service  is a versatile and widely-used manufacturing process, enabling the production of complex plastic parts with high precision. Among the many components in mold design, the  lifter system  plays a critical role in ejecting undercut features and maintaining product integrity. Designing a lifter system effectively requires balancing functionality, durability, and manufacturability. What is a Lifter in Injection Molding? A lifter is a moving component within the mold that helps release parts with undercut features during the ejection process. Undercuts are recesses or projections on the part that would otherwise prevent it from being ejected from the mold without damage. Lifters solve this challenge by moving laterally and retracting as the mold opens. Key Design Considerations 1. Geometry and Placement The lifter design begins with analyzing the part geometry and identifying undercuts. Lifters must be positioned strategically to effectively clear the...
