Hotflex® Flexible Tubular Heaters Ø8,5mm

The Hotflex Flexible Spiral Heater is the first tubular type heater that can be bent manually in all three dimensions worldwide. Easy to use, simple assembly, optimum thermal properties and simple storage (hotflex supplied in stock in flat condition with multiple lengths) are outstanding product arguments.

It provides high flexibility for engineers compared to conventional mold heating techniques (such as cartridge heating elements).

A better heat transfer, significant tool mass savings, replacement and lower energy consumption can be achieved with applications such as main line heating.

There is a wide variety of products in the desired size and wattage.
