What are the design limitations for incorporating ventilation slots in WPC outdoor trash cans?

When incorporating ventilation slots into Wood-Plastic Composite (WPC) outdoor trash cans, designers face several critical limitations. Primarily, the material composition of WPC restricts slot size and placement. Excessive or poorly placed slots can compromise the structural integrity of the can, leading to potential failure under load or impact. Secondly, the slots must be designed to facilitate proper drainage without allowing excessive water ingress, which can lead to odor retention and premature material degradation. The slots must also be sized to prevent small debris from clogging the drainage system while maintaining adequate airflow to mitigate moisture buildup and control odors. Furthermore, the manufacturing process for WPC can limit the complexity of slot shapes, often favoring simple, straight cuts over intricate designs to maintain production efficiency and cost-effectiveness. Balancing these mechanical, functional, and production constraints is essential for creating a durable and effective outdoor waste solution.
