The GL150-DY3M is a chain-type automatic roller coating machine designed to apply adhesive primer and cover coat to the external cylindrical surfaces of metal outer sleeves used in rubber bushings and vibration-control components.
It integrates automatic loading, chain conveying, precision roller coating, adhesive feeding, drying and exhaust gas treatment into a continuous production system. The machine provides uniform coating thickness, high adhesive utilization and stable performance for high-volume rubber-to-metal bonding applications.
The GL150-DY3M Automatic External Roller Coating Machine is independently designed and manufactured by ANGEM for the controlled application of bonding adhesive to the external cylindrical surfaces of metal components.
It is primarily used to apply adhesive primer and cover coat to metal outer sleeves and cylindrical inserts before rubber molding and vulcanization. Typical products include metal components used in shock absorber bushings, suspension bushings, vibration isolators and other rubber-to-metal bonded assemblies.
Chain-Type Continuous Production
The GL150-DY3M adopts a chain-type conveying system to transfer workpieces continuously through the loading, coating, drying and unloading processes.
This automated production method reduces manual handling and provides stable process timing for every workpiece. It is particularly suitable for manufacturers processing large quantities of cylindrical metal components.
Precision External Roller Coating
During the coating process, the external cylindrical surface of the workpiece comes into controlled contact with the coating roller. The precision control system coordinates workpiece movement, rotation and coating time to produce a uniform adhesive film.
Compared with manual brushing and conventional spraying, roller coating transfers adhesive directly to the required surface. This helps reduce overspray, improve adhesive utilization and provide better control over film thickness.
Automatic Adhesive Supply
The integrated adhesive supply system continuously circulates and delivers coating material to the roller coating unit. Stable adhesive feeding helps reduce variation in viscosity and coating quantity during continuous production.
The equipment can be configured for the application of adhesive primer and cover coat according to the customer’s rubber-to-metal bonding process.
Enclosed and Environmentally Controlled Operation
The GL150-DY3M adopts a fully enclosed coating structure to help contain adhesive residue and volatile emissions inside the working area.
The integrated exhaust gas treatment system collects and processes emissions generated during coating and drying, helping reduce their impact on the workshop environment and improve production safety.
Automated Process Control
The machine uses a precision control system to coordinate the complete production process. Operators can adjust relevant coating and drying parameters according to the workpiece, adhesive system and production requirements.
Its automated operation helps reduce dependence on manual coating, shorten production cycles and improve batch-to-batch consistency.
ANGEM can customize the machine according to the customer’s workpiece dimensions, coating position, adhesive system, required film thickness and target production capacity.

APPLICATION FIELD
Typical Applications of Roller Coating Machines
ANGEM roller coating machines are designed for the precise and uniform application of primers, bonding adhesives and functional liquid coatings on cylindrical metal components. They are widely used for preparing metal sleeves and inserts before rubber molding and vulcanization, especially in the automotive vibration-control and rubber-to-metal bonding industries.
Inner Bore Adhesive Coating
Inner bore roller coating machines apply a controlled layer of adhesive to the internal cylindrical surface of metal sleeves and bushings. Typical applications include inner sleeves for rubber bushings, suspension components, shock absorber bushings and other rubber-to-metal bonded parts.
Outer Diameter Adhesive Coating
Outer diameter roller coating machines are used to apply adhesive evenly to the external cylindrical surface of metal sleeves, tubes and inserts. They are suitable for outer sleeves, engine mount components, suspension bushings, vibration-control parts and other cylindrical metal components requiring consistent adhesive coverage.
Customized Roller Coating Solutions
The coating system can be customized according to the workpiece dimensions, inner or outer coating area, adhesive type, required film thickness, production capacity and loading method. ANGEM can provide manual, semi-automatic and fully automatic roller coating solutions for different production requirements.
