”Skillfully produced protection prolongs the machine’s lifespan.”

Low-pressure molding

From design to execution and delivery

Low-pressure molding of plastic is a safe and cost-effective method to protect electronics and connectors, manufacture connector housings, strain reliefs, and various plastic components.

The pressure and temperature used in low-pressure molding are moderate, making them safe for sensitive electronic components. We design and manufacture the necessary aluminum molds in-house, resulting in very low initial costs compared to injection molding.

Plastic molding provides effective protection for electronics against moisture, chemicals, as well as mechanical stress such as vibration and impacts.

Facts on the molding material we use

  • Fire rating V0
  • Static operating temperature -40°C – +125°C
  • Glass transition temperature -30°C
  • Molding temperature 190°C –210°C
  • Melting point 160°C
  • Thermal conductivity
    • 23°C 0,2W/mK
    • 180°C  0,6W/mK
  • Hardness Shore A 90
  • Molding pressure 10 – 40 bar
  • Viscosity 2,7 – 4,2 (very good penetrability)
