Obtaining a good shave requires a blade with the finest edge, so quality and production consistency are fundamental. Precise temperature control during the blade manufacturing process is critical, both in the heat treatment furnaces used for making the steel, and in the annealing and end tempering furnaces.
Supermax Corp of India, the world's second largest producer of disposable razor blades, now uses Eurotherm controllers in both of these applications as well as in the injection molding process for the razor body, and in special purpose printing machines. Supermax produces 10 million conventional double-sided razors and 1.2 million disposable razors per day.
“By using Eurotherm controllers, accurate PID control performance has been maintained," said Kalpesh Desai, Eurotherm’s sales manager in India, after Supermax asked Eurotherm to provide the temperature control for the company’s uniquely designed production machines. "This has provided Supermax with the high standard of temperature accuracy and uniformity demanded by the company. As a result, their production facilities worldwide maintain a consistent high quality, which in turn reduces scrap and increases productivity.”
Eurotherm supplies products including temperature and process controllers and indicators, signal conditioners, data recorders, data acquisition systems, sensors, actuators, and complete process automation solutions to processing and equipment manufacturers worldwide. In total, Eurotherm has supplied 250 PID temperature controllers and 460 single-phase thyristor units to Supermax, together with other products. Supermax is currently establishing production facilities in Mexico, Bangladesh, and Czech Republic and will be supplying all the manufacturing machines for these sites using Eurotherm instrumentation.
