Hydraulic Locking Cylinders

Improve Mold Performance with the KOR-LOK Side-Action System

With performance enhancements beyond standard hydraulic and locking systems, the PFA KOR-LOK side-action system is ideal for movable cores and core pulls on injection molds, improving mold performance with off-the-shelf solutions. It is a high-quality part production in a smaller mold footprint. Unlike many traditional spring-locking, hydraulic–activated solutions that often do not lock, preload, or […]

Sizing Core Pull Hydraulics: Forces & Calculations

Hydraulic cylinders are commonly used on injection molds to actuate movable core. When considering  “How to Size” a hydraulic cylinder for moving the core or preloading the core, PFA recommends to review three positions – initial breakaway, movement during stroke, and end position.  After determining the limiting condition, a proper size may be determined.  PFA’s […]
