7. Plastics industry

Electric resistance ovens are used in particular for drying, curing and polymerizing coatings on a wide variety of substrates – textiles, paper, wood, plastics, etc. – or for drying products themselves.

In plastics processing industries, certain products (granules, pellets, blocks, sheets, foils, etc.) are heated prior to processing in forced convection ovens (discontinuous or continuous), which can also be used for polymerization and stabilization of a wide range of products (temperatures between 120 and 250 ˚C, or even higher for special products). Other equipment is used for thermoforming (heated platens), as well as for welding and bending plastics (hot-air generators), preheating sheets before forming (hot-air ovens).

A large number of continuous or discontinuous forced convection electric ovens are used to heat heat shrinkable plastic...
