Through injection molding, thermoforming, extrusion and blow molding, plastics can be easily processed into a variety of complex shapes, with thousands of compounds to choose from and to design a variety of materials to meet specific requirements. Due to the use of plastics, many new features have emerged; product performance has improved; and most importantly, product costs have been greatly reduced.
At present, the competition in the white goods industry is extremely fierce, and all manufacturers are striving to improve production efficiency and reduce production costs. The plastic has the characteristics of light weight, easy processing and corrosion resistance, which meets these requirements. The application of polypropylene on the inner tub of the dishwasher is a traditional material for manufacturing the inner tub of the dishwasher. Although it has excellent corrosion resistance, it is costly. There are currently two ways to reduce its cost, using sprayed ordinary steel instead of stainless steel; or using polypropylene to make the inner barrel. In comparison, the use of polypropylene to make a drum in a dishwasher has a cost advantage, so this method is more advantageous.
The main requirements for polypropylene drums, the most important requirements are the strength of the material, the ability to withstand high temperatures and the processability associated with injection molding. The properties of a material are usually divided into three areas: material properties processing characteristics design characteristics should emphasize that there is a strong correlation between these properties. Material properties are often for a class of materials, and design properties are for an entity. Talking about both is inseparable from the size and shape of the product. Processing characteristics between Western Europe and various plastics in the appliance industry. Stainless steels, such as corrosion-resistant materials, have always accounted for a large proportion of the production costs of dishwashers.
