The 2 Component Meter Mix Dispense System is an automated solution designed for precise metering, mixing, and dispensing of two-part industrial materials. It independently delivers Components A and B at a preset mixing ratio and combines them through a static or dynamic mixing unit before application.

Suitable for compatible epoxy resin, silicone, polyurethane (PU), sealants, and industrial adhesives, this two-component dispensing system helps improve mixing consistency, dispensing repeatability, and production efficiency. With configurable metering pumps, material tanks, dispensing valves, and optional XYZ motion control, the system can be adapted to electronic potting, industrial sealing, adhesive bonding, and customized manufacturing processes.

Key Features

• Precise Two-Component Metering: Independently controls A and B material flow according to the required mixing ratio.
• Uniform Material Mixing: Supports static or dynamic mixing based on material characteristics and process requirements.
• Automated Dispensing: Integrates metering, mixing, and dispensing into one coordinated process.
• Wide Material Compatibility: Suitable for compatible epoxy, silicone, polyurethane, sealants, and industrial adhesives.
• Flexible Pump Configuration: Options include precision screw pumps, gear pumps, and other application-specific metering solutions.
• Stable Dispensing Performance: Helps maintain consistent material output and reduce unnecessary waste.
• Programmable Motion Control: Optional XYZ platform or robotic integration for complex dispensing paths.
• Customized System Integration: Can be configured with heating, stirring, vacuum degassing, pressure monitoring, and automatic cleaning where required.s.

Working Principle

This 2 component meter mix dispense system separately meters Part A (base resin / sealant) and Part B (curing agent / hardener) and mixes them inline right before dispensing.

1. Material Feeding & Storage

Part A and Part B two-component materials are stored in independent material tanks. For high-viscosity sealants, tanks can be equipped with stirring and heating functions. Material is fed into the servo metering pumps by pressure feeding or vacuum feeding. Low-level sensors monitor material volume and trigger an alarm when material is insufficient, preventing air from entering the metering system.

2. Precision Metering (Core Step)

Two independent servo positive displacement pumps drive Part A and Part B respectively. According to the preset mixing ratio, flow rate and dispensing volume in the PLC touchscreen, the servo system controls the rotation speed of each pump to deliver accurate volumes of A and B materials.

• Mixing ratio adjustable: 1:1 ~ 10:1
• Metering accuracy: ±1% The ratio is controlled by the pump displacement and servo speed, no manual adjustment of hardware.

3. Inline Mixing

The metered Part A and Part B flow simultaneously to the mixing head.

• Static mixing (standard): Materials flow through a disposable static mixer. The spiral baffles inside continuously split and recombine the two fluids to achieve homogeneous mixing. Best for epoxy, PU, medium-viscosity silicone sealant.
• Dynamic mixing (optional): A motor-driven rotating impeller inside the mixing head stirs materials forcibly. Suitable for high viscosity, poor flowability or hard-to-blend 2K sealants and adhesives.

4. Dispensing & Suck-back Anti-drip

After mixing, the homogeneous 2-component sealant/adhesive flows out from the dispensing nozzle onto the workpiece. Once the dispensing cycle finishes, the suck-back valve instantly pulls a small amount of material back. This eliminates dripping, stringing or glue tail, ensuring clean bead or shot finish.

5. PLC Closed-loop Control

The whole process is managed by PLC + touch screen. All parameters including ratio, flow rate, dispensing time, shot volume can be saved as product recipes. Users can quickly switch programs for different sealants or workpieces. Production data (dispensing volume, batch records) can be logged for traceability.

Core logic summary: Separate metering → Inline mixing → On-demand dispensing Materials are only mixed right before dispensing, avoiding waste of pre-mixed fast-curing 2K adhesive/sealant.
