To address the challenges of potting complex electronic components and elevate manufacturing precision, HOLS has engineered an advanced Vacuum Potting System featuring an innovative three-stage vacuum chamber design. This architecture ensures all core potting and encapsulation stages operate under continuous vacuum conditions, eliminating repetitive vacuum pumping and venting cycles that plague conventional systems.
The result is a dramatic reduction in overall cycle time paired with significantly boosted production throughput — making it a highly cost-effective solution for high-volume manufacturing. Optimized specifically for fast, accurate dispensing and potting of small-to-medium-sized components, the system excels across a wide spectrum of applications including PCB potting, ECU potting, sensor potting, power module encapsulation, BMS silicone potting, and connector potting.
Supporting both single-component and two-component (AB) epoxy materials, the integrated system pairs seamlessly with precision screw dispensing valves, dynamic mixing systems, and vacuum degassing capabilities to deliver bubble-free, void-free potting quality every time. Built for in-line automated production, it is the preferred choice for automotive electronics, new energy components, and industrial device manufacturers demanding uncompromising reliability at scale.

HOLS Vacuum Potting System were designed for cost-effective batch production at the highest levels of quality. All VDS systems feature a dispensing unit for 1C or 2C potting media, depending on your needs.
To meet many requirement, various cost-effective models are therefore available both as standalone systems or for integration in a production line.
Inline Automated Weighing
Effortless, rapid automation. Enjoy superior vacuum dispensing reliability and fewer rejects from consistent quality. Inline needle and weighing control replaces tedious off-cell weighing, keeping production running seamlessly.
Precision-engineered software
The Universal Visualization software offers a powerful user interface tailored to the application for all cells, vacuum dispensing systems and Process Module. The user always has an overview of the relevant data for all processes as well as associated monitoring, maintenance and analysis tasks.
Typical applications
Potting
Insulation
Conformal coating
Potting of coil products and transformers
LED potting
The vacuum potting system process prevents residual air bubbles in the coils of transformers, batteries, motors and other components, ensuring their safe and reliable operation. It avoids component malfunctions or complete failures caused by bubble formation during potting.
