The Silicone Phone Case Injection Mold for iPhone 17 Pro uses a precise insert injection mold for phone case design to achieve seamless bonding between plastic and silicone. This system allows a rigid plastic shell to be pre-inserted and then overmolded with soft LSR silicone through overmold injection tooling for plastic insert technology. It supports multi-cavity configurations and adopts a standard or cold runner design according to customer needs. Designed for vertical injection machines, the mold delivers stable clamping, smooth demolding, and high production efficiency.
