About Patt Technologies
Our History
Patt Technologies was founded in 1986 to solve real production challenges in plastic extrusion with custom, constant-pressure filtration. Nearly four decades later, we’ve expanded into plasma nitriding, precision machining, and design, delivering these services alongside cutting-edge filtration systems and wear components that improve uptime, pressure stability, and finished product quality.
Our Services
Patt Technologies designs and manufactures constant-pressure, continuous rotary filtration systems for a wide range of processes, from PVC recycling and high-temperature technical polymers to ultra-fine filtration for specialty compounding. We supply the complete ecosystem of accessories including precision dies, adapters, screen media, melt probes, and pressure transducers, engineered to integrate cleanly with your line. The result is an integrated, uptime-focused solution that improves pressure stability, product quality, and with a lower total cost of ownership than any of our competitors.
Beyond filtration, Patt offers in-house precision machining and plasma nitriding services, drawing on decades of production experience for automotive, medical, and aerospace applications, applying that experience to every project we touch.
Our Commitment to Quality
Patt’s attention to detail shows in rigorous inspection and testing of every system and component, delivering robust, reliable filtration that outperforms and lasts for decades.
