Meter, mix, and dispense demanding putty and paste materials with a system engineered around your chemistry, viscosity, ratio, and production goals.
Kirkco designs industrial dispensing equipment for high-viscosity materials that are difficult to move, meter, mix, and apply consistently by hand. Our putty and paste systems support application-specific configurations for adhesive dispensing, sealing, modeling, tooling, and other production processes where material control directly affects throughput, finish quality, and rework.

Designed Around Material Behavior and Application Demands
A successful putty and paste system must account for more than nominal viscosity. Kirkco can evaluate the variables that determine whether a system will deliver a stable and maintainable process:
Material viscosity and filler loading
Determines pump selection, supply requirements, pressure behavior, and the risk of material degradation or inconsistent flow.
Single- or two-component chemistry
Determines whether the process needs a single-material dispensing architecture or controlled ratio metering and mixing.
Mixing ratio and cure behavior
Determines whether the process needs a single-material dispensing architecture or controlled ratio metering and mixing.
Dispense geometry
Determines valve, hose, nozzle, and operator or robot interface requirements.
Container and material supply format
Affects drum handling, ram or pump configuration, replenishment, and production uptime.
Production volume and cycle time
Helps define flow-rate requirements, duty cycle, automation level, and process controls.
PU Bonding for Elevator Panel and Cab Assemblies
Executive Overview
Kirkco engineered a polyurethane bonding architecture for elevator panel and cab assemblies where structural integrity, vibration damping, and cosmetic finish are critical to passenger safety and long-term performance. The system was designed to deliver consistent bond lines across dissimilar substrates while supporting repeatable production workflows.
Business & Quality Drivers
Elevator manufacturers face stringent safety standards, aesthetic requirements, and warranty exposure. Manual adhesive application introduced variability in bond thickness and cure behavior, increasing the risk of rework and inconsistent panel performance over the service life of the equipment.
Process Requirements
The application required precise dispensing of one- or two-component polyurethane adhesives with controlled bead geometry and predictable open time. Adhesive placement needed to accommodate metal skins, composite panels, and internal stiffeners without squeeze-out or void formation.
System Architecture
The bonding platform utilizes bulk-fed PU metering equipment configured for stable ratio control and smooth material flow. Dispensing valves are selected to provide clean cutoff and repeatable start-stop behavior, enabling consistent application across panel sizes and configurations.
Controls & Validation
PLC-based controls manage dispense parameters, timing, and interlocks to ensure repeatable adhesive output. Process settings were validated to maintain consistent bond performance across multiple elevator models and production shifts.
Operational Performance
The architecture reduced material waste, improved cosmetic consistency, and stabilized cycle times. Production throughput increased by eliminating manual variability and reducing downstream inspection and rework.
