High‑precision dispensing, potting and coating are foundational manufacturing processes that directly determine product reliability, insulation performance, thermal management and long‑term service life for automotive electronics, power semiconductors and advanced industrial electronics. As a global intelligent manufacturing supplier, HOLS Automation delivers comprehensive dispensing solutions covering standard standalone equipment and fully custom turn‑key production lines, empowering manufacturers to achieve stable, repeatable high‑volume production for mission‑critical components.

Our complete dispensing portfolio spans seven core technical modules to match diverse material and process requirements: 

Potting & Encapsulation Solutions 

We provide both Vacuum Potting and Atmospheric Potting processes. Vacuum potting eliminates air bubbles inside complex housings to deliver void‑free encapsulation for IGBT, SiC power modules and power electronics. Atmospheric potting is optimized for large‑volume components with simplified process workflows. Both solutions enhance insulation, shock resistance and environmental protection for electronic assemblies.

Adhesive Dispensing Solutions 

Our adhesive dispensing portfolio includes FIPG/CIPG sealing and bonding adhesive application. Precision sealant beads are applied for ECU housings, PCB cover sealing and component joining, forming dust‑proof and moisture‑resistant sealing layers. High‑accuracy bonding dispensing ensures consistent bond‑line thickness for structural assembly of automotive electronic parts.

Thermal Material Solutions 

Precision dispensing of thermal gap fillers, thermal gels and thermal adhesives enables reliable heat dissipation for high‑power electronic units. Controlled volume output guarantees uniform thermal interface layers, lowering operating temperature for ECUs, inverters and power modules under heavy‑load working conditions.

Coating Solutions 

Tailored coating processes support conformal coating and surface protection requirements, forming protective layers against humidity, chemical corrosion and particle contamination for circuit boards and sensitive electronic assemblies.

Material and Preparation Technology 

Stable raw‑material handling is the prerequisite for consistent dispensing quality. Our technology includes vacuum material degassing to remove entrapped air from multi‑component compounds, together with follow‑plate feeding systems for high‑viscosity materials, preventing material degradation and feeding interruptions during continuous production.

Metering Technology 

Multiple metering platforms are available for different material viscosities and mixing ratios: Piston Metering System, Screw Metering System and Gear Pump System. Flexible metering selections support single‑component and two‑component materials, delivering accurate volumetric output with minimal deviation for mass‑production scenarios.

Customized Curing Solutions 

Complementing our dispensing equipment, we supply tailored curing solutions including multi‑level curing ovens. Matching curing profiles for potting compounds, adhesives and thermal materials ensures complete material cross‑linking and stable mechanical performance after dispensing operations.

Our dispensing & potting technologies serve high‑demand sectors: automotive Tier 1 suppliers, automotive sensors, ECU controllers, IGBT/SiC power semiconductors, e‑drive inverters, on‑board chargers (OBC), automotive LED lighting, BMS, industrial inverters, servo drives, power supplies, PCB assemblies, EMS manufacturing, rail‑transit electronics, energy‑storage modules, security and home‑appliance electronics.

Beyond standalone dispensing machines, HOLS provides full‑stack integration capability. We embed dispensing, potting and coating stations into complete automated assembly‑test turn‑key lines. Customers can obtain single process equipment or full‑range production solutions from process validation, equipment design to on‑site commissioning. All systems comply with automotive‑grade manufacturing standards, helping global customers cut process risks and improve production yield.
