2-Part Epoxy Dispensing Equipment for Electronic Potting and Encapsulation

Our 2-part epoxy dispensing equipment is an automatic meter-mix system dedicated to accurate proportioning, mixing and dispensing of two-component epoxy resin. Powered by high-precision servo metering pumps, it controls A and B epoxy ratio and shot volume consistently, eliminating ratio drift and unstable curing caused by manual mixing.

This epoxy dispensing unit can work standalone or integrate with XYZ gantry robot and vacuum chamber for void-free potting. It handles low, medium and filled high-viscosity epoxy for electrical and electronic encapsulation. Multiple dispensing recipes can be saved for fast model changeover. Custom configuration and pre-sales epoxy potting test are offered.

Key Features

High-precision metering pumps accurately control the dispensing volume and mixing ratio of epoxy resin (A) and hardener (B), helping ensure consistent mixing and reliable curing performance.

2. Stable Mixing Ratio

Supports various A/B mixing ratios according to application requirements. Precise proportioning helps reduce material waste, incomplete curing, and defects caused by incorrect mixing.

3. Uniform Mixing Performance

Available with static or dynamic mixing systems to achieve homogeneous blending of two-part epoxy materials. The mixing method can be selected according to material viscosity and filler content.

4. Wide Range of Epoxy Materials

Suitable for compatible two-component epoxy resins with different viscosities, including selected filled compounds used for electronic potting, encapsulation, insulation, and protection.

5. Adjustable Dispensing Volume

Adjust dispensing time, flow rate, and shot volume according to workpiece requirements. Supports dot dispensing, line dispensing, and quantitative filling for different electronic components.

6. Optional Vacuum Potting

An optional vacuum chamber helps reduce trapped air bubbles during potting. It is suitable for electronic applications requiring reliable insulation and protection, subject to material and process conditions.

7. Flexible Automation Integration

Can be integrated with manual fixtures, XYZ gantry systems, robotic arms, or automated production lines to improve dispensing consistency and production efficiency.

8. Custom Solutions for Electronic Components

Designed for applications such as current transformers, voltage transformers, LED drivers, sensors, solid-state relays, capacitors, and circuit boards. Customized configurations are available based on your workpiece and production requirements.

9. Easy Maintenance

Replaceable static mixing tubes help reduce cleaning time and material buildup. An optional automatic flushing system can support continuous production where required.

Working Process

1. Material Preparation

Epoxy resin (Component A) and hardener (Component B) are stored separately to prevent premature reaction. Material heating or stirring can be configured when required by the resin properties.

2. Precision Metering

The metering system delivers Components A and B according to the preset mixing ratio and required dispensing volume, helping maintain consistent material proportions throughout production.

3. Mixing

The two components enter a static or dynamic mixer, where they are blended into a uniform mixture. The appropriate mixing method depends on the material viscosity, filler content, and curing characteristics.

4. Dispensing & Potting

The mixed epoxy is dispensed into the designated areas of electronic components or housings. Dispensing parameters can be adjusted to suit different workpiece sizes, filling volumes, and production requirements.

5. Vacuum Degassing (Optional)

For applications sensitive to trapped air bubbles, an optional vacuum process can help remove air from the material or reduce voids during potting. The specific process depends on the resin formulation and workpiece structure.

6. Curing

After dispensing, the epoxy cures according to the material manufacturer’s recommended conditions. The cured resin forms a protective layer that helps provide electrical insulation and resistance to moisture, dust, and mechanical stress.

Note: The working process can be customized according to the epoxy material, workpiece design, required output, and production environment.

 FAQ

Q1: What is a two component epoxy dispensing machine?

A two component epoxy dispensing machine is automatic equipment to meter, mix and dispense two-part epoxy resin (resin A + hardener B). It is used for electronic potting, encapsulation and casting.

Q2: What epoxy material can this machine handle?

It works for unfilled epoxy and filled epoxy with silica powder or other fillers. It supports low to high viscosity two-component epoxy.

Q3: What mixing ratios are available?

Standard ratios:1:1,2:1,3:1,4:1,5:1,10:1. We can customize special mixing ratios based on your epoxy datasheet.

Q4: Can this machine do vacuum epoxy potting?

Yes. We can add a vacuum chamber module. Vacuum potting removes air bubbles and improves insulation performance for transformers and sensors.

Q5: What is the dispensing accuracy?

Mixing ratio accuracy: ±2%. Flow repeatability: ±2%. Actual performance depends on epoxy viscosity, temperature and filler content.

Q6: Static mixer or dynamic mixer, which one to choose?

Static mixer is for most normal epoxy applications with low maintenance. Dynamic mixer is recommended for high viscosity or heavily filled epoxy. We will suggest after checking your glue sample.

Q7: How to clean the two component epoxy dispensing machine?

Static mixing tubes are disposable. Main pipeline can be flushed with matched cleaning solvent. Automatic cleaning function is optional for long continuous production.

Q8: Can I store multiple dispensing recipes?

Yes. Touch screen supports saving multiple recipes. You can quickly switch between different products on production line.
