PFA

What PFA does

PFA, Inc. is a Wisconsin-based, privately held industrial manufacturer (founded 1989; 11-50 employees) specializing in hydraulic locking cylinders, quick die change (QDC) and quick mold change (QMC) systems, and modular end-of-arm automation (EOAT) for robotic applications. The company's core technology centers on proprietary mechanical locking architectures — most notably the KOR-LOK® "true locking" preloading cylinder, which delivers 100% preload at zero pressure and up to 10x the holding force of standard cylinders — and on rapid-changeover systems (Hydra-Jaws™ QMC plates, Hydra-Latch™ Quick Knockout, DIE-LOK™ multi-slide components, and the SWITCHMAX® sensor connectivity platform) that enable single-minute exchange of dies (SMED). Its portfolio serves die casting, metal stamping, plastic/injection molding, robotic automation, and industrial locking/braking applications, with products marketed under five registered trademarks and CAD-supported engineering documentation.

PFA monetizes primarily through direct sales of engineered components and custom systems, with pricing on a quote basis (Net 30 terms; no public price list), complemented by an in-house e-commerce store for standard KOR-LOK, SWITCHMAX, and gripper pad SKUs. GTM is sales-led: direct outreach, online quote request forms (e.g., KOR-LOK Online Quote), six downloadable PDF catalogs, and content marketing across trade articles and social platforms. Distribution is North American, anchored by headquarters and manufacturing in Germantown, Wisconsin, with a dedicated Mexican sales/contact channel (Spanish-language portal) and Canadian reach. The product footprint was materially expanded by the 2005 acquisition of American Aerostar (QMC and QDC product lines) and extended again in 2021 with the KOR-LOK Series 70 "Mini" cylinder targeting small-mold and small-press applications.

The business model is that of a niche, design-and-make industrial component supplier: high engineering content, custom-specification sales, Made-in-USA manufacturing, and multi-decade customer relationships within stamping, die casting, and injection molding shops. There is no disclosed external funding, no public financials, no subsidiaries, and no parent company; ownership is independent and no management team or named investor information is provided in the source data.

Core offering

PFA designs and manufactures industrial tooling including hydraulic locking cylinders, quick mold change (QMC) and quick die change (QDC) systems, sensor connectivity components, and modular robotic end-of-arm automation (EOAT) products. The company serves die casting, metal stamping, injection molding, and robotic automation manufacturers with both standard catalog items sold via an online store and custom-engineered solutions sold through direct sales.

Product overview

PFA is a manufacturer of industrial tooling and automation solutions comprising multiple distinct product lines: KOR-LOK® Side Action Systems (preloading and locking core pull cylinders for injection molds and die cast dies); Hydra-Jaws™ Quick Mold Change and Hydra-Latch™ Quick Knockout Systems (QMC for rapid mold changes); Quick Die Change Systems (QDC for SMED applications including hydraulic clamps, die lifters, and mechanical solutions); SWITCHMAX® Connectivity Cables (sensor integration for injection molding machines); Self-Locking and Braking Cylinders (high-force holding and braking actuators); Modular End-of-Arm Automation (EOAT including robotic grippers, gripper pads, compliance devices, and crash protection); and DIE-LOK™ Multi-Slide Systems (multi-slide die casting solutions). Both off-the-shelf and custom solutions are available.

Products and services

• KOR-LOK Side Action Systems Preloading and locking core pull cylinders for injection molds and die cast dies, providing improved part quality, cycle speed, and smaller mold/smaller press capability with 100% preload at zero pressure.
• Hydra-Jaws Quick Mold Change (QMC) Quick mold change plates and quick knockout systems providing consistent clamping and rapid mold changes for a wide range of mold sizes in a single machine, with clamps that move to fit the mold.
• Hydra-Latch Quick Knockout Systems Quick knockout systems integrated with QMC for rapid mold changes and knockout operations.
• Quick Die Change (QDC) Systems Systems for single minute exchange of dies (SMED) including locking and check valve hydraulic clamping, die rails/lifters, 5,000 psi pump controllers, mechanical die lifters, and bolster extensions for metal stamping presses.
• SWITCHMAX Connectivity Cables Sensor connectivity solution connecting multiple side-action mold cylinder sensors in series for plug-and-play connections, featuring cross connected sensor verification, PNP and relay sensor connections, and relay power adaptors.
• Self-Locking and Braking Cylinders Cylinders providing locking and holding forces up to 10 times more than standard cylinders, available in lock-on-extend, lock-on-retract, and air braking (KPS) configurations for holding loads at any position in stroke.
• Modular End-of-Arm Automation (EOAT) Modular robotic automation products including grippers, gripper pads, compliance devices, and crash protection for integrated robotic end-effector solutions.
