Automatic Inner Bore Roll Coating Line for Automotive Bushings
GNL100-D3M | Adhesive Coating Project for ASIMCO Anhui
Project Overview
Three-Stage Inner Bore Adhesive Roll Coating Line
ANGEM designed and manufactured this GNL100-D3M automatic inner bore adhesive roll coating line for ASIMCO NVH Technologies Co., Ltd. (Anhui). Developed for automotive bushing components, the system integrates automatic feeding, preheating, primer roll coating, two cover-coat stages, multi-stage drying and automatic unloading into one continuous production process.
✓ Production cycle of 6–8 seconds, processing 1–2 parts per cycle
✓ Three independent roll coating stations: one primer coat and two cover-coat layers
✓ Automatic feeding, part orientation, preheating, drying and unloading
✓ PLC and touchscreen control with adjustable coating time, rotation speed and temperature
Integrated Coating Process
Automatic Feeding & Orientation
Bulk parts are lifted from the hopper, automatically oriented by the vibratory feeder and transferred onto the chain conveyor.
Preheating
The oriented components are preheated at a controlled temperature before primer application.
Primer Roll Coating
The inner bore receives a controlled primer layer through the first automatic roll coating station.
Primer Drying
The primer-coated components pass through the hot-air drying section before cover-coat application.
First Cover-Coat Roll Coating
The first cover-coat layer is applied to the inner bore by the second independent roll coating station.
Intermediate Drying
The first cover-coat layer is dried under controlled hot-air conditions before the next coating stage.
Second Cover-Coat Roll Coating
The third roll coating station applies the second cover-coat layer to achieve the required coating thickness.
Final Drying & Automatic Collection
The finished components complete final drying and are automatically discharged into the collection bin.
Key System Configuration
Bulk Parts Loading Hopper
Operators load the metal bushing components into the hopper in batches, reducing frequent manual feeding during continuous production.
Inner Bore Roll Coating Unit
The component rotates while the coating mechanism applies adhesive directly and uniformly to the inner cylindrical surface.
Automatic Feeding Elevator
The plate-chain elevator continuously lifts the components from the hopper and transfers them to the orientation and conveying system.
Automatic Parts Discharge
After the final drying stage, the finished components are automatically discharged into the collection bin for the next production process.
Automatic Part Transfer System
Automatic transfer units move the components accurately between the conveyor, coating positions and subsequent processing stages.
Production Monitoring System
The monitoring display allows operators to check machine status and production information for stable and efficient operation.
