Product Description:
Automated Mold Design / Hydraulic Core Pulling Injection Mold
Hydraulic core pulling injection molds are ideal for plastic parts with undercuts, grooves, or side holes that cannot be ejected by standard means. Using a hydraulic cylinder, the mold activates a core-pulling mechanism to ensure smooth and accurate demolding. This technology is widely used in plastic injection molding for automotive, electronics, and industrial products.

At Sung I Industrial, we offer advanced mold development and custom manufacturing solutions. Whether for OEM/ODM projects or high-precision parts, our molds support complex processes such as insert molding and overmolding, and are compatible with various engineering plastics. Through full vertical integration, we manage everything from design to delivery—ensuring faster lead times, stable quality, and cost control. Hydraulic core pulling molds are essential for manufacturers seeking efficiency, durability, and flexibility in modern injection molding production.
