KPD vacuum potting machines provide precise 2K metering, mixing and bubble-free encapsulation for electronics, power modules, sensors, automotive and new energy applications.
KPD Vacuum Potting Machine is an automated dispensing and encapsulation system designed for applications that require high-quality, bubble-free potting. By combining vacuum processing with precise 2K metering and mixing technology, the system helps remove trapped air and improve the consistency, reliability and appearance of cured products.
The machine is suitable for epoxy, polyurethane (PU), silicone and other two-component potting materials. It can accurately control adhesive ratio, dispensing volume, mixing and potting parameters according to different product requirements.
The vacuum potting process is particularly suitable for electronic and electrical components where excellent insulation, moisture resistance, mechanical protection and long-term reliability are required.

Two-component materials’ encapsulating and casting production are important to enhance electronic products. No matter if your product is for business selling, or for household consuming, nowadays everyone has higher quality requirements and expectations. Furthermore, the protection of the product is not only to optimize the function of the product, but also to prolong the service life of the product, thereby reducing production waste. In electronic products the parts and components are generally composed of different metals and sensitive chemical combined materials. The more precise the product, the more high-tech the product it is, with this, it requires higher protection, so that it can be optimized according to the requirements. In doing so, it can state of long-term operation without being affected by the surrounding environmental conditions. Our two-component potting machines are specially designed for this production, as well as our vacuum encapsulating and casting potting machines. These machines can accurately degas the two-component adhesive materials base on the ratio, meter, mix, and homogenously and continually to the products. These materials cannot be applying manually, they need to use machines, which can be supplied in large quantities, continuously, accurately, and for long time of works. With the materials provided by such equipment, the product will have better protection, heat dissipation, waterproof, moisture-proof, encryption (to protect the circuitry design, and components used).
