Equipment for dosage, mixing and filling of high viscosity compounds based on the vacuum system

Purpose

Universal equipment for dosing, mixing and applying of polymer systems and potting compounds based on polyurethanes, epoxide resins, filled polymers, silicones, etc.
The equipment allows to process all types of rigid, elastic, integral foam polyurethane systems, polyurethane compounds and polyurethane glues with the viscosity of basic components equal to 10-70 000 mPa*sec and obtain items of any shape the weight of which is not less than 0.002 kg.

Application

• Filling of electronic devices, components and equipment (engines, transformers, capacitors, etc.) with the compound;
• Production of cast isolation for electrical devices (transformers, capacitors, inductors, etc.);
• Production of any other type of items made of polyurethane foam, as well as the production of items based on potting compounds, filling compounds and adhesives.
