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 […]
Hydraulic Locking Cylinders
Any time a new injection mold is completed and ready for use, it is vital to ensure that the mold maker sets up in the injection molding machine to perform a test run. The process of setting up an injection molding machine is often much more than just loading and fixing the mold and pressing […]
PFA Inc.’s mini hydraulic locking cylinder delivers 8,000 pounds of preload force in a new narrow format, enabling multiple small cores to nest together and time independently.
PFA’s new 70 series “mini” hydraulic locking cylinder features tremendous preloading capacity in a small cylinder footprint.
PFA provides enhanced an enhanced mold designer, mold builder, and molder user experience with great support around the KOR-LOK Side Action system for high preload core pull cylinder operations.
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 […]
Improve complex injection-molded part quality and profitability by reducing mold base size and preloading slides from a solid structure to ensure placement.
As the leader in the design and manufacturer of several industry-preferred products, PFA Inc. strives to not only provide innovative solutions to common problems but also exceed our customer’s expectations.
