THERMOPLASTICS

Hotmelt moulding materials for connectors, sensors and whole modules

Hotmelt moulding machines work at lower temperatures and far lower pressures than in normal plastic injection moulding. The process is therefore also called low pressure moulding, or LPM. That is kind to the parts, lets the thermoplastics cure quickly and is relatively cost-effective, without impacting the qualitative characteristics of the method. Our hotmelt moulding materials are suitable for connectors, sensors and even whole electronic modules. They withstand both permafrost and average oven temperatures, are resistant to salt and alcohol and can be put into any required shape.

Finding the right potting material for hotmelt moulding is an art in itself. Cooling times are short, with just a few seconds for total enclosure of even the most filigree parts without leaving any cavities, while still coming out of the machine undistorted. We offer comprehensive advice, take care of tool design and toolmaking and even provide the entire processing technology from tank to extruder, so all you actually need to do is to choose the colour.

Advantages of Thermoplastics

Thermoplastics are highly valued in the field of component protection for several reasons:

  • Chemical Resistance: Many thermoplastics provide excellent resistance to chemicals and corrosion, making them ideal for protecting components in harsh environments.
  • Flexibility and Moldability: Thermoplastics can be shaped into almost any form, offering significant design flexibility. Once cooled, they retain their shape.
  • Insulating Properties: They possess good electrical insulating properties, making them well-suited for use in the electronics and electrical industries.
  • Solvent-Free 1-Component Systems: Usable without mixing, this material allows for fast cycle times.
  • Environmentally Friendly: Many thermoplastics are made from bio-based materials.
  • Component-Friendly Processing: The low-pressure injection molding process is a component-friendly procedure, as the hotmelt material can be processed at low pressures and temperatures.
