Welcome to PFA, Inc.

Located just North of Milwaukee, Wisconsin, PFA is a leader in the design and manufacture of True Locking Core Pull Cylinders (KOR-LOK®), Quick Die Change Systems (QDC), Quick Mold Change Systems (QMC), Multi-Slide Die Casting Solutions, Industrial Locking and Braking Cylinders, and Robotic Automation End-Effectors.

KOR-LOK® Side-Action Systems and DIE-LOK

Multi-slide Systems for pre-loading and true locking of moveable cores on injection molds and die cast dies, provide improved part quality, speed and performance over traditional cam pin and toggle methods.

SWITCHMAX® Connectivity Components and Electrical Cables

Integrate various “on mold” sensors (relay, mechanical, and proximity DC) into a single signal interface common on most injection molding machines. LED indication also assists operators. No more complex wiring – just plug & play.

Hydra-Jaws Quick Mold Change and Hydra-Latch Quick Knockout Systems

Provide consistent clamping and support rapid mold changes for a wide range of mold sizes in a single machine. Clamps move to fit the mold!

Quick Die Change Systems

Provide easily customized solutions for stamping die “quick change”. Bolster extensions, die rails/lifters, check valve and locking clamps, and electronic 5,000 psi pump controllers are just a few of the options available.

Self-Locking and Braking Cylinders

Hold large loads many times that of standard cylinders, even with pressure removed, making them ideal for a wide variety of industrial applications, where large load capacity or loss of air scenarios demand greater performance and simplicity.

Robotic Automation End Effectors

Modular products allow the coupling of Grippers, Gripper Pads (GP), Compliance Devices (RCC) and Crash Protection (OPD) into a simple and integrated robotic end-effector solution.
