Use of non-corrosive materials is also important because it maximizes product life. Low maintenance is obviously a time saver and, in the long run, is a money saver, too. Compactness, or small "footprint," is also a plus since plant space is limited and can be very expensive.
BAND AND CARTRIDGE HEATERS
The Value Band heater from Fast Heat, Inc., Elmhurst, Ill., is being introduced as a competitively priced product for heating nozzles on injection molding machines. Also from Fast Heat is the new Expandable Better Band, which has a cuff-like design that expands to the diameter of the heat sink A material that absorbs heat. Typically made of aluminum, heat sinks are widely used in amplifiers and other electronic devices that build up heat. Small heat sinks are the most economical method for cooling microprocessors and other chips. . You can now replace a single burned-out heater in the middle of multiple heaters with little difficulty, the company says. And you can stock one size of Expandable Better Band for two different voltages. Each heater is composed of two pieces with each part rated at half the wattage wattage
the output or consumption of an electric device expressed in watts. and voltage of the entire unit.
