Application and Technological Breakthroughs of Two Component Glue Potting Machines in New Energy Battery Packaging

Second Intelligent has strong solution and technical service capabilities, and will provide customized glue filling machine solutions to customers based on their adhesive characteristics, production process requirements, production capacity requirements

The rapid development of the new energy industry has raised higher requirements for battery module packaging processes — achieving high-strength insulating sealing while maintaining consistency and efficiency in mass production. The Two Component Glue Potting Machine is playing an increasingly important role in this field and continues to achieve technological breakthroughs.

Core Potting Requirements for Battery Packs

Power battery packs contain numerous cells and high-voltage connection points. Potting adhesive must provide electrical insulation, thermal conductivity, moisture and corrosion resistance, and other multi-functional properties. Polyurethane and epoxy two-component machine adhesives are the mainstream choices, but their high viscosity and long curing times pose stringent challenges for potting equipment.

Technological Solutions from Two Component Glue Potting Machines

1. High-Flow Precision Metering: Battery pack potting requires large adhesive volumes, with single potting volumes reaching hundreds of milliliters to several liters. New-generation Two Component Glue Potting Machines use high-displacement servo metering pumps, maintaining ±1% ratio accuracy while meeting high-flow demands.

2. Multi-Stage Potting Programs: Supports pre-set timed sequences for injecting different adhesive volumes in multiple stages, preventing overflow and stress concentration caused by single-shot injection.

3. Closed-Loop Temperature Control: Adhesive viscosity changes significantly with temperature. Built-in heating and temperature control modules ensure stable adhesive flow within the optimal temperature range.

4. Vision-Assisted Positioning: Industrial cameras identify battery pack potting port positions and automatically correct coordinate offsets, improving potting precision.

Industry Practice Data

After a leading battery manufacturer introduced the Two Component Glue Potting Machine, potting defect rates dropped from 2.3% to 0.4%, single-shift capacity increased by 40%, and adhesive waste decreased by 25%. These figures prove the irreplaceable value of automated potting in the new energy sector.

As solid-state battery and fast-charging technologies continue to evolve, potting processes will keep advancing, and the Two Component Glue Potting Machine will iterate toward higher precision and greater intelligence.

Sensors are widely used in automotive and industrial equipment, where operating environments are complex and often present challenges such as high temperatures, high pressure, and corrosion. The core application of potting machines in sensor connectors is to achieve precise potting and protective sealing. Through automated metering, mixing, dispensing, and curing control, they ensure that sensor connectors maintain waterproofing, dust proofing, insulation, shock resistance, and temperature resistance in harsh environments. These machines are critical process equipment in fields such as automotive electronics, industrial sensing, and new energy storage.
