High-Precision​ Two Component Sealant Applicator for Insulating Glass

Key Features

• Accurate Two-Component Mixing

  The machine uses independently driven pumps for Part A and Part B, maintaining a precise mixing ratio throughout the dispensing cycle. Ratio deviation is minimized to ensure proper curing and long-term seal integrity.

  Static Mixing System

  A high-efficiency static mixer blends the two components without introducing air bubbles. The mixed sealant is delivered with consistent density, producing a clean, durable bead on every IG unit.

  PLC Control with HMI Touchscreen

  The control system allows operators to set mixing ratios, monitor system pressure, and adjust dispensing parameters through an intuitive interface. Quick recipe recall reduces changeover time between jobs.

  Compatible with Multiple Sealant Types

  Designed to work with two-part silicone, polysulfide, and polyurethane sealants. Switching between sealant types requires minimal adjustment, making the machine suitable for diverse production needs.

  Heavy-Duty Industrial Build

  The frame is constructed from reinforced steel to maintain stability during high-speed operation. Pneumatic and hydraulic components are selected for durability under continuous use.

  Low Maintenance Design

  Key components are arranged for easy access. The static mixer, filters, and seals can be serviced or replaced without extensive disassembly, keeping production downtime to a minimum.

Technical Specifications

Key Components

• A-component pump (base sealant): A 250 mm diameter pneumatic motor drives the piston pump that draws the base sealant from the 55-gallon drum. Pump pressure ratio is 50:1, translating 0.6 MPa air pressure into approximately 30 MPa maximum extrusion pressure.
• B-component pump (curing agent): An 80 mm diameter pneumatic motor drives a smaller displacement pump matched to the curing agent volume required by the set ratio. The mechanical linkage between the A and B motors fixes the proportioning range from 7:1 to 14:1.
• Proportioning pump and valve block: Alloy valve seats and seals handle the abrasive nature of filled sealant compounds. The valve block is designed to be disassembled for cleaning and seal replacement during scheduled maintenance.
• Curing agent filtration units: Two in-line filters with replaceable elements trap particles upstream of the proportioning pump. Filter mesh size can be selected based on the sealant manufacturer's recommendation.
• Static mixing tube: A disposable or cleanable static mixer attached at the dispensing gun outlet. Internal helical elements fold the two sealant streams together as the material is extruded, completing the mixing process immediately before application.
• Dispensing gun: A pneumatic trigger gun with an ergonomic handle. Pulling the trigger activates the pump cycle; releasing it stops material flow. A safety lock prevents accidental discharge.

Applications

This Two Component Sealant Applicator for Insulating Glass is used in insulating glass production facilities for edge sealing of double and triple glazed units. It applies polysulfide or polyurethane-based two-component sealants onto the spacer perimeter of assembled IGU frames. The pneumatic design also supports on-site glazing work for curtain wall and structural glass installations where power supply may be unreliable. Typical users include insulating glass manufacturers, glass processing plants serving the window and door industry, and facade installation contractors requiring mobile sealant application equipment.

How It Works）

The Two Component Sealant Applicator operates through a straightforward process:

Part A (base compound) and Part B (curing agent) are fed from their original drums or pails into separate pump systems.

The PLC control system regulates the pump speed for each component to achieve the target mixing ratio.

Both components are delivered to the static mixing chamber, where they are blended without bubbles or inconsistencies.

The mixed sealant is dispensed through the applicator head onto the spacer or glass edge of the insulating glass unit.

The operator monitors and adjusts parameters in real time through the HMI touchscreen.

Engineered for Excellence

Consistent Bead Quality

The high-precision pump system maintains stable dispensing pressure, ensuring a uniform sealant bead across the entire perimeter of the insulating glass unit. No gaps, no overflows.

Easy Maintenance & Cleaning

The modular design allows for quick access to core components. The static mixer can be disassembled and cleaned in minutes, reducing production downtime.

Operator Safety

Equipped with emergency stop buttons, pressure relief valves, and safety guards to ensure a secure working environment for your operators.

Customization Available

We offer OEM/ODM services. The machine can be customized to fit your specific production line layout, including vertical or horizontal configurations.
