The amount of plastic in household appliances accounts for 40%, and injection plastic parts are favored by the industry

 

As a traditional pillar industry of national economy, household appliance industry plays an important role in economic development. At present, the amount of plastic in household appliances has reached 40% of the weight ratio, and with the increasingly light weight, miniaturization and personalization of household appliances, the application of plastic will be more and more extensive.

 

 

Status of application

 

At present, the application of plastics in household appliances is more and more common, and many steel household appliances components have been replaced by plastic products. It is reported that thermoplastics are mainly used in household appliances, including PP, ABS, HIPS, AS, PC, POM, PA, PBT, and PPS. PP can be used for washing machine inside and outside barrels, fan leaf shell, refrigerator drawer, rice cooker shell, induction cooker base, soy milk machine head cover, electric kettle shell, etc. ABS can be used for air conditioning shell, washing machine panel, refrigerator liner, microwave oven facade, small home appliance shell, etc. HIPS is used for air conditioning housing, refrigerator liner, home appliance housing, etc. PAS is used for fan blade, juicer transparent shell, transparent water tank, etc. PC can be used for switch button, transparent shell, water box, heat and flame resistant shell, etc. POM can be used for household appliances gear, sliding parts, microwave oven door hook bracket, etc. A can be used for switch, sliding parts, electrical components, etc. BT can be used for coil skeleton, switch bracket, etc. PPS can be used for turntable bracket, High heat resistant precision structural parts.

 

 

 

Overall, the plastic parts of the refrigerator account for more than 70% of the overall parts, and most of them are assembled on the external surface, playing a role in appearance decoration. Plastics are widely used in refrigerators. The commonly used plastic materials for refrigerators include ABS, PE, PP, nylon PA, POM, polyurethane foam, plastic powder materials, etc.

 

 

 

Universal plastics also play a crucial role in the development of home appliance technology. Commonly used plastics have the advantages of light weight, high specific strength, excellent electrical insulation performance, excellent chemical stability, good friction and wear resistance, light transmission and protection performance, vibration and noise reduction performance, etc. These advantages make the application of plastics in home appliances very important. In addition to general plastics, engineering plastics are also one of the materials for household appliances spare parts. Although the amount is not large, it will play a role in some important parts.

 

 

 

Plastic has a certain advantage in the application of home appliances. The density of general plastics is low, the density of all kinds of foam plastics is lower, at the same time, the specific strength of some reinforced plastics even exceeds that of steel. In addition, almost all plastics have excellent electrical insulation properties.

 

 

 

Directions of Development

 

The industry pointed out the problems faced by the development of household appliance industry: at present, the rapid growth of cost is one of the main challenges faced by the household appliance industry, and the requirements for energy saving and environmental protection are also increasing. Although the household appliance industry has achieved a qualitative leap in energy saving and emission reduction and environmental protection, the level of energy saving and comprehensive utilization of resources of some products lags behind that of developed countries.

 

 

 

It is for this reason that home appliance companies hope that the focus of research and development in the field of raw materials should be to replace the original resource-poor and high-cost materials with more resource-rich and lower-cost raw materials. The production technology is developing in the direction of short process, low pollution, low energy consumption and green manufacturing.
