Máquina automática de recubrimiento adhesivo para el diámetro interior de casquillos de goma con insertos metálicos GNP100-DY3M -ANGEM
The GNP100-DY3M is a chain-type automatic roller coating machine designed to apply adhesive primer and cover coat to the inner bores of cylindrical metal inserts and sleeves used in rubber bushings and vibration-control components.
The machine integrates automatic loading, chain conveying, adhesive feeding, inner bore roller coating, drying, inspection and unloading into a continuous production system. Its fully enclosed structure, precision coating control and automatic adhesive supply help manufacturers achieve uniform film thickness, high adhesive utilization and stable high-volume production.
Automatic Adhesive Coating for Inner Bore Surfaces
The GNP100-DY3M Automatic Inner Bore Roller Coating Machine is independently developed and manufactured by ANGEM for applying bonding adhesive to internal cylindrical surfaces.
It is primarily used to apply adhesive primer and cover coat to the inner bores of metal inserts, sleeves and cores before rubber molding and vulcanization. Typical applications include rubber bushings, shock absorber components, suspension bushings and industrial vibration isolators.
Precision Inner Bore Roller Coating
The machine uses a controlled roller coating mechanism to transfer adhesive directly to the inner cylindrical surface of the workpiece. The precision control system coordinates the coating roller, workpiece positioning and coating time to produce a uniform adhesive film inside the bore.
Compared with manual brushing and conventional spraying, inner bore roller coating provides more controlled adhesive application while reducing overspray and unnecessary adhesive consumption.
Chain-Type Continuous Production
The GNP100-DY3M uses a chain conveyor system to transfer workpieces continuously through the loading, coating, drying, inspection and unloading stations.
This automatic conveying process maintains stable production timing and reduces manual handling. It is particularly suitable for high-volume manufacturing of cylindrical metal components.
Automatic Adhesive Supply
The integrated adhesive supply system automatically circulates, monitors and delivers coating material to the roller coating unit. Stable adhesive feeding helps maintain consistent coating conditions during continuous operation.
The equipment can be configured for adhesive primer and cover coat application according to the customer’s rubber-to-metal bonding process.
Integrated Drying System
After coating, the workpieces are transferred automatically through the drying section. The controlled drying process helps stabilize the adhesive film before the components enter subsequent manufacturing processes.
Drying parameters can be adjusted according to the adhesive system, workpiece material and production requirements.
Inspection and Process Monitoring
The machine incorporates weighing, color inspection and process monitoring functions to support stable coating quality. Abnormal conditions can be detected during production, helping reduce defective workpieces and improve batch consistency.
Fully Enclosed and Environmentally Controlled Design
The fully enclosed coating structure helps contain adhesive residue and volatile emissions inside the machine. The exhaust gas collection and discharge system reduces the impact of coating and drying operations on the workshop environment.
Explosion-proof protection can be incorporated according to the adhesive system and project safety requirements.
Fully Automatic Operation
The complete machine integrates the following processes:
Automatic loading
Chain conveying
Adhesive feeding
Inner bore roller coating
Drying
Process control
Color inspection
Automatic unloading
Exhaust gas collection and discharge
This integrated process helps increase production efficiency, shorten production cycles and reduce dependence on manual coating.
ANGEM can customize the equipment according to the customer’s workpiece dimensions, inner bore size, 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.
