In modern electronics and electrical manufacturing, epoxy potting is a critical process for protecting core components from environmental hazards and ensuring long-term reliability. A high-performance epoxy potting machineis the core equipment that standardizes, automates, and refines this process.

1. The Core Value of Epoxy Potting

The potting process involves injecting liquid epoxy resin into a cavity containing electronic components and curing it to form a solid protective layer. Its key functions are:

  • Superior Insulation & Protection: Prevents ingress of moisture, dust, and chemical contaminants.

  • Thermal & Mechanical Support: Secures internal components, dissipates stress, and some formulations aid heat conduction.

  • Enhanced Structural Integrity: Improves vibration and shock resistance of the entire module.

  • Enabled Miniaturization: Fills all voids, allowing for more compact electrical designs.

2. Key Technologies of an Epoxy Potting Machine

An advanced potting machine does more than just "dispense glue"; it integrates multiple precision control technologies:

  1. Precision Metering & Mixing System

    • Uses servo or gear pumps for high-accuracy ratio control(up to ±0.5%-1%) between epoxy resin (Component A) and hardener (Component B).

    • Employs static or dynamic mixersto ensure instant, homogeneous mixing, preventing localized non-curing.

  2. Deaeration & Vacuum Processing System

    • Material Pre-Deaeration: Vacuum degassing of resin in the supply tank to eliminate air bubbles from the raw material.

    • Vacuum Potting: Optional vacuum chamber for degassing the product during or after potting, thoroughly removing bubbles from windings or complex structuresto eliminate insulation risks.

  3. Intelligent Temperature Control & Delivery System

    • Heated and temperature-controlled tanks and hoses maintain the optimal viscosity of the epoxy for consistent flow and potting results.

    • Stable fluid delivery system ensures uniform shot volume and uninterrupted flow.

  4. Automated Control & Execution System

    • PLC Program Control: Allows pre-setting and storage of potting paths, doses, and parameters for multiple products.

    • Multi-Axis Motion Platform: A robotic arm or 3-axis platform equipped with a dispensing valve enables precise potting along complex paths.

    • Vision Positioning & Gravimetric Feedback(Optional): Enhances positioning accuracy for delicate products and enables closed-loop dose control via weighing.

3. Primary Application Fields

Electronic product potting

  • New Energy Vehicles: Potting protection for motor controllers, onboard chargers, Battery Management Systems (BMS).

  • Power Electronics: PV inverter modules, UPS power supplies, transformer modules.

  • Industrial Control: Sensors, servo drives, PLC modules.

  • Consumer Electronics: High-end power adapters, LED drivers.

4. Key Considerations for Choosing Potting Equipment
