The AJL.ZG100 Inner Bore Automatic Adhesive Coating Machine is an independently developed solution by Angem Precision Machinery Co., Ltd. (Suzhou), featuring fully proprietary intellectual property. It is specifically engineered for applying adhesive coatings to the inner bore surfaces of automotive damping components and metal-rubber composite part frameworks.
By fundamentally redesigning both the working principle and mechanical structure, this system eliminates the common drawbacks of traditional spray coating equipment — including missed coverage, overspray, and excessive adhesive waste.
The machine integrates a fully automated workflow covering automatic loading, adhesive application, drying, and automatic unloading, delivering a seamless end-to-end production process. Its core performance metrics meet advanced industry standards, making it the ideal solution for inner-wall adhesive coating of automotive damping parts and metal-rubber skeletal components.

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.
