How Vacuum Potting Machines Are Reshaping Precision Manufacturing

In new energy vehicles, electronic components and power insulators, the potting process determines a product's insulation, moisture resistance and service life. Yet increasingly complex adhesive formulations and tighter process demands have left manual mixing and basic potting equipment far behind.

Stubborn bubbles, settled filler, inaccurate ratios and difficult cleaning don't just slow production — they drive up reject rates. The SMART-VC-G two-component vacuum potting machine from GOOGIO was built to solve exactly these problems.

Three Potting Pain Points, Addressed

1. Stubborn bubbles causing insulation failure?
Conventional atmospheric potting traps air in the adhesive, forming bubbles that degrade electrical performance. Our machine uses a 100L rotary-vane vacuum pump set reaching an ultimate vacuum below 50Pa. From degassing in the tank to dispensing inside the vacuum casting chamber, the entire process runs under negative pressure, eliminating micro-bubbles and ensuring a dense, flawless potting layer.

2. High-filler materials settling or jamming the pump?
For epoxy resins loaded with hard fillers such as silica powder or alumina (Al₂O₃), the machine uses dedicated high-precision gear pumps and wear-resistant screw metering pumps. Just as important, an automatic circulation anti-settling function keeps material moving: when the machine stops, adhesive in the lines circulates back to the tank, aided by pneumatic stirring, so filler never settles or separates and the adhesive stays uniform.

3. Inaccurate mixing ratios driving up scrap?
For mix ratios from 1:1 to 10:1, the SMART-VC-G drives its metering pumps with servo motors and a pressure feedback system, achieving ≤±1% mixing and dispensing accuracy. Whatever the formulation, dosing stays precise and off-ratio curing defects are eliminated.

Core Technology for an Unmanned Potting Shop

• Intelligent PLC control: stores 99 process recipes. Vacuum level, temperature, time, flow rate and mix ratio can all be programmed in stages on the touchscreen and recalled with one touch for consistent production every time.

• Precise temperature control: tanks and lines are fitted with heated insulation layers, adjustable from room temperature to 120℃ with ±2℃ accuracy — ideal for temperature-sensitive materials such as polyurethane and silicone.

• Three-axis robot integration: a three-axis robot inside the vacuum casting chamber performs continuous, precise dispensing of points, lines, planes and arcs anywhere within the 800×800×800mm cavity.

• One-touch high-pressure atomized cleaning: when changing material or shutting down, an automatic high-pressure atomized cleaning cycle leaves no residue, greatly reducing manual maintenance costs.

Wide Range of Applications

From deep impregnation of electronic transformers and encapsulation of new energy vehicle IGBT modules to potting of high-voltage insulators, sensors and LED modules, the SMART-VC-G delivers a tailored solution.
