Small hard plastic discs play a key role in keeping horizontal wet-process lines steady. The 22mm Hard Plastic Wheel Disc provides a rigid, polished contact surface to reduce conveyance jitter, guide rail drag, and handling errors during PCB and FPC transfer.
Core Advantages: PP/PE/PVDF/PBT material options, high hardness, chemical resistance, dimensional stability, and polished low-friction surface.
Selection Recommendations: Choose the suitable material, bore diameter, disc width, and contact profile based on tank chemistry, guide rail design, shaft size, and panel thickness.
Applications: Guide rail systems, flip mechanisms, loading systems, etching lines, developing chambers, abrasive cleaning equipment, and mechanical positioning assemblies.
Stable Operation Guarantee: Helps reduce transport jitter, track misalignment, surface scratching, motor strain, and downtime caused by unstable board hand-offs.
Eliminating Misalignment and Conveyance Jitter in Horizontal Lines.
Unstable board transport leads to critical defects, including positional misalignment and surface scratching during the sensitive wet-process stages. Our 22mm Hard Plastic Wheel Discs are engineered to solve these mechanical inconsistencies by providing a rigid, high-precision contact surface. By utilizing advanced engineering plastics like PVDF and high-density PE, these discs resist swelling and deformation under constant immersion. This ensures that your PCB/FPC panels maintain a consistent travel path through drive systems, reducing equipment downtime and minimizing the potential for expensive scrap due to mechanical handling errors.
Engineering-Grade Polymers for Demanding Environments
Tailored Solutions for Your Conveyor Architecture
These precision wheel discs are essential components for PCB, FPC, and LCD equipment manufacturers requiring reliable board handling. They excel in high-speed wet-process machines, including automated etching lines, developing chambers, and abrasive cleaning systems. Within these environments, they serve as the backbone for stable transport in guide rail systems, board flipping units, and mechanical positioning assemblies. By maintaining precise support even in complex multi-tank configurations, these discs ensure that every panel remains perfectly aligned, whether traversing through critical copper removal stages or high-precision masking and cleaning modules.
In high-pressure PCB etching lines, these wheel discs function as the primary point of contact for board support during transport. Their high-hardness composition allows them to withstand the repetitive impact of high-pressure sprays without surface degradation. By ensuring smooth, vibration-free movement, they significantly improve the consistency of etching results across the entire panel surface. This stability allows for faster throughput and higher yield rates, as operators experience fewer manual adjustments and reduced equipment maintenance cycles related to track misalignment.
In automated flip and loading systems, the precision of these discs is the key to preventing mechanical damage. By reducing drag and ensuring perfect seating in the guide rails, they enable seamless board hand-offs between processing modules. This operational smoothness reduces the physical stress on the driving motor and gear assemblies, directly contributing to a lower total cost of ownership and higher ROI through increased equipment longevity. When implemented across the production line, these components turn potential mechanical bottlenecks into reliable, high-performance transit zones.
