Precise heating and measuring in modern plastics processing

In plastics processing, precise temperature and pressure control is crucial for stable production and high product quality. Particularity when melting and conveying the plastic material, temperatures must be kept uniform and reproducible. Nozzle heating elements and cartridge heaters are primarily used for this purpose.

Nozzle heating elements ensure a constant nozzle temperature during injection molding, as this zone immediately before injection is particularly sensitive to fluctuations. Thanks to their robust design, high power density and close thermal coupling, they react quickly to temperature changes and ensure uniform heating of the material. Cartridge heaters are used in tools, hot runners, nozzles and heating plates and offer a high heating capacity despite their compact design. Their even heat distribution and long service life make them a central component in many heating areas where precise and stable temperature control is required.

In addition to heating, measuring the process parameters plays an equally important role. Mineral insulated thermocouples are ideal for extruders, hot runners and molds due to their flexibility, temperature resistance and short response times. They provide stable and reliable temperature values even under high mechanical and thermal loads. These are supplemented by melt pressure sensors are used to measure the pressure of the plastic melt. They enable precise control of the melt pressure, detect disruptions in the material flow and therefore make a significant contribution to process reliability and consistent product quality.

The coordinated interaction of efficient heating elements and precise measuring technology results in a controlled, reproducible and energy-efficient manufacturing process – the basis of modern plastics production.

Selection of suitable products

Cartridge heaters

Metal-sheathed high-performance cartridge heater (HLP) with ground outer jacket made of stainless steel. Special construction and high compression allow an extremely high surface load, i.e. the accommodation of high power in a very small space. UL approved available.

Bayonet sensor

Thanks to the special measuring tip, the bayonet probes are particularly suitable for flat and pointed bores. The Form-stable compression spring can be used for a variety of applications and serves as cable kink protection. Built-in length can be varied as required thanks to the adjustable bayonet lock.

Nozzle heating elements & tubular cartridges

Low-mass, high-density heating elements with which a very high output can be accommodated in a small space. They are available with or without built-in Thermocouples.

Ground sensor

Thanks to the special measuring tip, the bayonet probes are particularly suitable for flat and pointed bores. The Form-stable compression spring can be used for a variety of applications and serves as cable kink protection. Built-in length can be varied as required thanks to the adjustable bayonet lock.

Mass pressure sensors

Our melt pressure sensors are characterized in particular by increased service life, high material quality, precise measuring behavior and a food-safe transmission medium. The melt pressure sensors are made entirely of stainless steel, and the use of a special and innovative diaphragm means that the known errors of diaphragm rupture during fusion shrinkage are a thing of the past. A special coating protects the diaphragm against sticky and abrasive substances. The result of selected materials, a special manufacturing process and the high-precision electronic unit ensures a stable measuring process without the known interference of temperature drift, such as with the NaK filling medium. By dispensing with environmentally harmful materials, our Sensors can also be used for food and pharmaceutical applications (FDA-compliant).
