Technology is constantly evolving. From the phone in your pocket to the razer you shave with, things are just getting more and more advanced by the second. In the realm of cell phones, manufacturers are in a new age “space race” to see who can get the most cameras on the back of their phones. […]
Hydraulic Locking Cylinders
For the injection molding industry, high production output and low machine downtime is the key to success. Having reliable systems installed into your machines and using cost-efficient materials for your molds will help you accomplish this goal. PFA Inc. has revolutionized the clamping system in injection molding machines (IMM) to work seamlessly with aluminum molds. […]
The injection molding process dates back to 1872, when the Hyatt brothers, who invented the first machine, patented their idea. And it has not rested since then. But as time moves on, more and more complex molds are needed. These complex molds come with complex geometries and undercuts. You must know how to choose the […]
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 […]
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 […]
