The design principles of plastic reels primarily revolve around core engineering objectives such as structural strength, lightweighting, wear resistance, transmission efficiency, and cost control.
Hollow Shafts or Thin-Walled Structures: Designed to reduce weight, lower material costs, and minimize rotational inertia while maintaining sufficient rigidity.
Application of Engineering Plastics: Commonly utilizes materials such as polypropylene (PP), polyamide (PA), and polycarbonate (PC), balancing the requirements for corrosion resistance, electrical insulation, and processability.
Innovation in Recycled Plastics: Some manufacturers (e.g., Nordic Semiconductor) incorporate recycled plastics; these materials must undergo rigorous testing to ensure they do not deform or jam during shipping and automated pick-and-place assembly.
