Solutions for the plastics & packaging industry

Dedicated solutions for the plastics & packaging industry

heating elements, sensors, control & technical services

One of our biggest markets since founding is the South African plastics industry.

This industry has in the past faced severe challenges, emerging from a typically low efficiency industry and low investment to a more sophisticated industry using modern technologies, such as hotrunner systems, to remain competitive.

Our contribution to this industry has been a substantial one. We were founded in 1980, where we kick-started our production of heaters and sensors for the plastics industry. In 1990 we started producing micabands and manufacturing our own controllers.Shortly thereafter, we adopted the agencies for overseas brands Gefran, Hotset, Elstein, Thermoplay hotrunner systems.
In 2000 we broke into the export market with our sensors.
