Vacuum Cabinet Automatic Potting Machine
Core Functions & Applications
The Vacuum Cabinet Automatic Potting Machine integrates a sealed vacuum cabinet with automated potting systems, designed for precise glue filling (e.g., epoxy, silicone) into workpieces like sensors, transformers, PCB assemblies, and automotive electronic modules. Its core advantage lies in the vacuum environment: it removes air from the cabinet before/ during potting, eliminating air bubbles in the glue—critical for products requiring high sealing, insulation, or structural stability (e.g., waterproof sensors, high-voltage components).
It automates the entire process: workpiece positioning, vacuuming (vacuum degree up to -98kPa), glue mixing (for two-component adhesives), precise potting (volume accuracy ±1%), and curing (optional built-in heating module). This replaces manual potting, which is prone to bubble formation and inconsistent glue volume, ensuring uniform encapsulation and long-term product reliability.
Widely used in industries like automotive electronics (potting ECUs, sensors), new energy (battery module encapsulation), industrial control (circuit board protection), and medical devices (sealing precision instruments), it meets strict requirements for environmental resistance (moisture, dust, vibration) and electrical insulation.
Key Technical Features
Bubble-Free Potting: The vacuum cabinet extracts air from workpieces and glue, reducing bubble rate to less than 0.1%—avoids insulation failures or structural weaknesses caused by bubbles.
Dual-Component Compatibility: Equipped with automatic mixing and metering systems, supports glue mixing ratios (1:1 to 10:1) and viscosities (500-100,000 cP) for two-component adhesives.
Precision Control: Uses servo-driven motion axes and high-precision metering pumps, with positioning accuracy ±0.02mm and potting speed adjustable (10-50 ml/min) to match workpiece size.
Safety & Efficiency: Features vacuum overpressure protection, glue level alarms, and a touchscreen interface (stores 50+ potting programs). The cabinet’s modular design allows easy loading/unloading, cutting downtime.
