Heat in Plastic Industry
Plastic processing is heat processing: every injection moulding machine, extruder, hot-runner mould and thermoformer depends on heaters that hold the melt at exactly the right temperature. MaxVolt manufactures band, cartridge, hot-runner coil, cast-in and infrared heaters for processors and machine builders.
In plastic processing, a few degrees make the difference between a good part and a reject. Barrel zones, nozzles, hot-runner tips and dies each need steady, responsive heat — and when a heater fails, the machine stops.
MaxVolt supplies the full set of heaters a plastics plant uses every day, in standard sizes for quick replacement and in custom designs for special moulds, dies and machines.
Problems we solve for this industry
Band heater burn-outs
Loose clamping and poor contact with the barrel make band heaters overheat and fail.
Our approach: Bands are made to the exact barrel diameter with proper clamping, sized for the zone.
Hot-runner tip temperature
Nozzle tips that run hot or cold cause drooling, stringing or frozen gates.
Our approach: Coil heaters with built-in thermocouples put the heat and the sensor right at the nozzle.
Energy lost from barrels
Bare barrel heaters radiate a large share of their energy into the shop.
Our approach: Insulated ceramic band heaters reduce those losses.
Uneven sheet heating
Uneven heating in thermoforming gives thin spots and webbing.
Our approach: Zoned infrared heaters let each area of the sheet be trimmed.

Plastic Industry heating — common questions
Mica bands are compact and economical for normal temperatures. Ceramic bands handle higher temperatures and, with insulation, cut energy losses — a good choice for machines running round the clock.
