PLC Controlled​ Two Component Sealant Applicator for Insulating Glass

Key Features

• Fully pneumatic operation: The Two Component Sealant Applicator for Insulating Glass runs entirely on compressed air. No electrical connection is required, which makes it practical for use at construction sites, in temporary workshops, or in locations where stable electricity supply is not available.
• Proportioning and mixing: A hydraulic proportioning pump, driven by pneumatic motors with diameters of 250 mm for component A and 80 mm for component B, delivers the two sealant streams at a set ratio adjustable between 7:1 and 14:1. A static mixing tube then combines the materials before dispensing.
• Valve and seal design: The base material pump, curing agent pump, and proportioning pump valve ports are machined from a special alloy selected for resistance to sealant abrasion and chemical attack. The manufacturer states zero leakage under working pressure when properly maintained.
• Dual filtration on curing agent line: Two filter units are installed in the curing agent hydraulic circuit. They remove particulates before the component reaches the proportioning pump, contributing to consistent mix quality and reducing the chance of nozzle clogging.
• Air supply and consumption: The machine requires a compressed air supply between 0.5 and 0.8 MPa, with maximum air consumption of 0.8 m³/min under full load. A standard air preparation unit with filter, regulator, and lubricator is included.

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.
