Two-Component Vacuum Dispensing Machine
The two-component vacuum dispensing machine combines PLC-based intelligent control with vacuum degassing to meter, mix and pot A/B materials at ±0.5% ratio accuracy — widely used in electronics, electrical and medical manufacturing.
- Precise metering, ±0.5% ratio accuracy
- Vacuum degassing, bubble-free potting
- Dynamic or static mixing optional
- PLC intelligent touch-screen control
- Automatic line cleaning
- Multi-tank multi-unit customization
Product Overview
The two-component vacuum dispensing machine is an automated potting system designed for two-component epoxy, polyurethane and silicone materials. High-precision metering pumps dose the A and B components at the set ratio; mixing and degassing take place under vacuum, and the mixed resin is then dispensed into the workpiece. This effectively eliminates air entrapment and voids, significantly improving the protection and first-pass yield of insulated components and electronic parts.
Key Advantages
- Precise metering: ratio accuracy up to ±0.5% for batch-to-batch consistency
- Vacuum degassing: mixing and potting under negative pressure, free of voids and bubbles
- Mixing options: dynamic or static mixing to match different viscosities and processes
- Intelligent control: PLC programming with touch-screen HMI, one-touch recipe recall
- Automatic cleaning: self-cleaning fluid lines for fast material changes and easy maintenance
- Built to order: multi-tank and multi-unit configurations tailored to your process
Working Process
- Feeding: A and B components are stored in separate tanks with heating, stirring and vacuum pre-degassing
- Metering: high-precision pumps deliver both components at the set ratio
- Mixing: a static or dynamic mixing tube homogenizes the resin before the dispensing head
- Vacuum potting: parts are potted inside a vacuum chamber, preventing air entrapment
- Curing and cleaning: parts move on to curing while the machine auto-cleans for the next cycle
