Dishwasher racks, also known as dishwasher baskets or tines, are typically made of plastic or vinyl-coated metal. The choice of material depends on the manufacturer and model of the dishwasher. Here are some details about each material:
Plastic: Many dishwasher racks are made from durable plastic, such as polypropylene. Plastic racks are lightweight, resistant to corrosion, and offer good protection against chipping or scratching delicate items. They can withstand the heat and water exposure during dishwasher cycles. Plastic racks are often designed with adjustable tines and compartments to accommodate various dish sizes and shapes.
Vinyl-Coated Metal: Some dishwasher racks are constructed with a metal frame that is coated with vinyl or PVC. The vinyl coating provides an additional layer of protection and prevents the metal from coming into direct contact with the dishes. The metal frame adds strength and stability to the rack.
Both plastic and vinyl-coated metal racks are designed to hold dishes, glasses, utensils, and other items securely during the dishwasher cycle. They are engineered to withstand the high temperatures and water pressure of dishwasher operations.
It's worth noting that the specific materials used for dishwasher racks can vary between different dishwasher brands and models. Manufacturers may use proprietary materials or combinations of materials to achieve the desired performance and durability.
