Dynisco History

Established in 1953, Dynisco was one of the first companies to apply strain gauge technology to pressure transducers for a variety of markets and industries and the first company to design a transducer specifically to measure melt pressure during the extrusion process. In addition, over the years, Dynisco has grown through acquisition to include products such as melt indexers, rheometers, polymer evalutaion equipment and other auxiliary equipment for polymer processing and plastics extrusion.


Dedication to our ISO 9001:2000 certification assures that all Dynisco products are designed and manufactured to the highest quality standards. And our products are backed by a comprehensive service and repair program and unmatched technical support. Our experience, expertise, and service all are directed toward improving product quality and manufacturing efficiency for our customers.


Dynisco has a network of Manufacturing Sites and Sales Offices around the Globe, many of whom have over twenty years of experience with our products. Also, sales representatives and distributors worldwide supplement these direct offices throughout Europe and the Pacific Rim.
Today, Dynisco is the international leader in pressure and temperature measurement and control products for the plastics industry. We've solved some of the most challenging measurement problems in extrusion, molding, process control and general industrial applications. Our sensors meet the rigid standards of approval agencies such as CE, FM, SIRA, PTB, CSA and others. We've built our reputation by providing high accuracy pressure measurement at high temperatures, with transducers that withstand the most abrasive and corrosive production environments. Continued investment in R&D allows Dynisco to offer hundreds of models of transducers and transmitters and the latest sensing technologies.


Our extensive line of polymer testing equipment grew from Kayeness, Inc., which Dynisco acquired in 1987. Today we supply both on-line and laboratory capillary rheometers, laboratory melt indexers, on-line slit rheometers, on-line infrared analysis, a variety of impact testers, coefficient of friction testers, contact angle testers, film tensile testers and other small test devices. Through our innovative work with electronics and mechanical design, we’ve carved a niche in the polymer test marketplace by providing the highest performance per cost ratio in the business. Dynisco meets the physical testing needs of the plastics, food, and rubber industries by providing high quality equipment and services at low cost.


In 1990 Dynisco acquired Normag Gear Pumps and followed that by adding Extek Screen Changers in 1994. Extrusion processors worldwide came to rely on Dynisco gear pumps and screen changers to meet their most demanding specifications for sheet, cast film, profile, tubing, pipe, wire and cable or compounding applications. The Beringer product line was acquired by Madison Capital Group in 1998. It was combined with the Extrusion group. The Beringer product line included screen changers, cleaning ovens, and pelletizers. In 2006 the Extrusion group was divested to Xaloy in 2006, now known as Xaloy Extrusion.


On December 15th, 2006 Roper Industries, Inc. of Duluth, GA (NYSE: ROP) acquired Dynisco LLC from Audax Group of Boston, MA. Dynisco has been added to the Roper’s Energy Systems & Controls segment.
