Shaping Up Manufacturing Processes

Using Watlow's THERMOPOLYMER heaters in a manufacturing process can lower costs and make the process more efficient because the THERMOPOLYMER heater serves as the heating solution, not just the heating element.

To help improve the manufacturing process, THERMOPOLYMER heaters can:

Lead to new design possibilities thanks to the ability to mould a heater into a structural and functional component
Provide better product performance through uniform heat distribution and by putting the heat only where it is needed
Increase heater life and usage
Resist corrosion and scaling thanks to the chemical properties unique to polymers

Features	Benefits
Fewer parts and less labour required Corrosion and scale resistant Natural, non-stick surface Reduced power consumption Heat is concentrated only in areas where it is needed	Reduced overall costs Longer heater life Easy to clean Energy efficient Uniform heat distribution
