Hard Plastic Wheel Discs

The Structural Backbone of Heavy-Duty PCB Conveyors In horizontal wet processing, structural rigidity is non-negotiable. If your conveyor discs soften or deform under chemical load, the result is “board bowing”—a leading cause of substrate jams and uneven etching. Since 2008, QXY has provided the PCB industry with high-density hard plastic wheel discs designed to act as the rigid foundation of the transport line. Unlike generic plastic parts, our discs are precision-machined from premium PP and POM to maintain their dimensional stability in the harshest chemical baths. We don’t just provide wheels; we provide the mechanical insurance that your conveyor maintains its flat-plane alignment, shift after shift.

Material Selection Guide

Rigid Support Tailored to Your Process Chemistry

Not all “hard” plastics are equal. Choosing the wrong polymer can lead to premature cracking or thermal expansion issues. We offer specialized material grades to match your specific module:

  • High-Density PP (Polypropylene) Discs: The go-to choice for acid and alkali modules. These discs offer exceptional chemical inertness, ensuring they won’t swell or degrade when submerged in aggressive etching or stripping chemistries.
  • POM (Polyoxymethylene) Precision Discs: Engineered for high-mechanical load sections. POM provides superior wear resistance and a lower coefficient of friction, making it ideal for high-speed transmission where mechanical durability is the priority.
  • Glass-Fiber Reinforced Options: For extra-wide horizontal lines where extra stiffness is required to prevent shaft deflection under the weight of heavy copper-clad laminates.

Industry Applications

Engineered for High-Load & High-Chemical Zones

Our hard plastic discs are built to survive where others fail:

  • Primary Etching & Developing: These discs maintain their edge profile even under constant chemical spray, ensuring consistent board support and preventing the “sagging” that ruins precision circuit patterns.
  • Heavy Panel Processing: Designed for thick, multi-layer board production where the cumulative weight of the substrates requires a wheel disc that won’t “flat-spot” during temporary line stops.
  • OEM Equipment Integration: We provide equipment builders with drop-in replacements that meet standard industry tolerances. Whether you are scaling a new production line or retrofitting an existing etching machine, our discs are machined to your CAD drawings for a perfect, vibration-free fit.
