Kemtech is proud to be associated with JENNINGS INTERNATIONAL CORPORATION who are the world leaders in supply of PTFE Fine Power Paste Extrusion machinery solutions.

JENNINGS INTERNATIONAL are manufacturers of quality PTFE Fine Powder Paste Extrusion equipment since 1953. Jennings has a state of the art machining and fabrication facility. When combined with designs which have proven themselves over the years, we have a winning formula which allows a high degree of control over the manufacturing process, and thus the quality of the final product. Over 95% of our machined and fabricated parts are produced in house by Jennings. This allows us to offer industry leading quality.

Our success has allowed us to reinvest in new equipment which further enhances the quality of our parts and manufacturing processes. To complement our existing CNC Department, Jennings has recently added a state of the art Mitsubishi Laser for the processing of sheet and light plate, as well as a Mazak Vertical Machining Center, which is capable of machining platens up to 55" by 79". This equipment allows unsurpassed precision in sheet metal fabrication and machining.

Because of the quality of our designs, many of our machines have been in service for decades. Our customers have welcomed our machine Re-Manufacturing program with great enthusiasm. We can bring your machine up to current specifications, incorporating state of the art features such as computer control and our touch screen console.

PTFE Paste Extrusion is a batch process. The product yield is directly related to the stroke length of the Extruder. Jennings offers the longest stroke Extruders on the world market at 120", approximately 3 meters. Therefore, Jennings offers the longest product yields per extrusion run. Jennings also pays particular attention to the control of the Extrusion speed which is directly related to the quality of the end product. Jennings has a state of the art oven system to maximize the speed of the Extrusion.

Jennings has many many times more number of PTFE FPP Line extruders installations worldwide then any other company.

Being a PTFE Fine Powder Paste Extrusion solutions specialist.
