ADHESIVE TECHNOLOGY + APPLICATION ENGINEERING
A custom adhesive and equipment solution simplified double-sided dispensing for an underground mining application, reducing applications from three to one per side.
Based on a real customer project. All visuals on this page are illustrative. Actual customer equipment and products are not shown, and customer-specific details have been modified for confidentiality.
The challenge
The customer’s components required UV adhesive on both sides. Operators manually dispensed the adhesive, left the components standing to allow bubbles to escape, and then cured them in a mercury-lamp oven. Each side required three rounds of dispensing and curing, resulting in six cycles per component and repeated manual handling.
The components were intended for deep underground mining environments, where resistance to high temperatures and high humidity was required. Wiring and other structures also shielded some adhesive areas from UV light.
The solution: adhesive and process developed together
XINCHENG combined a UV/moisture dual-cure adhesive system with custom-designed dispensing and curing equipment. A single clamping setup and automatic alignment simplified positioning, while fixture rotation enabled processing of the opposite side.
- Vacuum degassing before dispensing: remove entrapped air during adhesive preparation rather than relying on standing time after each application.
- One dispensing application per side: replace three repeated applications on each side with one.
- Ultrasonic-assisted leveling: use vibration to help the adhesive level rapidly after dispensing.
- LED curing and fixture rotation: cure the first side, rotate the component, and repeat the process on the opposite side.
- Secondary moisture cure: enable subsequent curing in areas shielded from UV light by wiring or other structures.
Project overview
Before and after
| Process | Previous method | Improved method |
|---|---|---|
| Dispensing | Manual; three applications per side | Automated; one application per side |
| Bubble removal | Standing after dispensing | Vacuum degassing before dispensing |
| Leveling | Standing period | Ultrasonic-assisted leveling |
| Light curing | Mercury-lamp oven | LED curing |
| Double-sided processing | Repeated manual handling | Single clamping setup with fixture rotation |
| Shadowed areas | Not reached by direct UV exposure | Secondary moisture cure |
The project outcome
The revised workflow reduced dispensing applications from six to two per component and brought positioning, dispensing, assisted leveling, and LED curing into a coordinated equipment sequence. This reduced repeated processing and handling steps.
Results relate to this specific project. Process settings, cure conditions, material compatibility, and production capacity must be assessed for each application.
