According to Deng Haibin, a plastics research engineer at Midea Group Purchasing Center, the total annual plastic consumption is about 350,000 tons, of which 85%-90% (ABS, PP, PS) and engineering plastics account for about 10%. The five major engineering plastics are also involved, as well as PPS, ASA, PCTG and engineering alloy materials. The main suppliers of engineering materials are BASF, Sabic, EMS and so on.

Midea's plastics suppliers are more diversified. When selecting suppliers, they mainly consider five aspects: technology, cost, service, quality and delivery. When talking about the differences between domestic and foreign material suppliers, Deng Haibin pointed out that foreign suppliers have better technology and services, and the material performance is relatively stable, but the cost is higher and the delivery time is longer. Domestic engineering material suppliers are more assured in terms of cost and delivery, and current technology, service and quality are constantly improving. Another advantage of foreign material suppliers is that the special certification of materials is more complete. They will certify materials according to the needs of different product market applications, such as NSF certification for water treatment equipment applications, and some special heat resistance in UL yellow cards. Certifications for weathering, chemical resistance, and flame retardancy, and regional certifications related to food hygiene such as FDA, EU, LFGB, etc., so they have the advantage of certification in the use of export products. With the fierce competition in the market, special material certification is gradually popularized among domestic material suppliers. However, the material certification of domestic material suppliers requires continuous efforts and improvement in order to adapt to the requirements of the export market as soon as possible.

“In the United States, the research of new materials and new applications will be carried out through the materials research department, and the demand for products will be developed, and then the right materials suppliers will be sought. Suppliers need to select suitable materials according to material performance, material certification and other requirements. Generally, appropriate material processing techniques and mold design schemes will be proposed, and corresponding mold manufacturers, injection molding plants and other materials will be recommended.

The competition in the home appliance industry is becoming increasingly fierce. The development of engineering plastics by plastics, steel, plastics, functionality and appearance has become a trend. “Although the cost of steel is relatively low, plastics can be injection molded at one time because of its simple processing technology, which reduces many processing and post-processing processes. There is still an advantage in plastic-based steel. The application of plastic-based copper is also relatively mature, such as In the past, many copper joints of pipes have been able to replace copper products with modified nylon. The functional realization of household appliances, such as coffee machines, juice machines and other wear-resistant, heat-resistant and food-contact parts, has also been It is solved by applying special engineering materials. The appearance of household appliances is also an important factor in brand marketing. The appearance of the products is more attractive to consumers. Various plastics are modified by filling to make the appearance of imitation metal and imitation paint. , not only achieves better visual effects, but also achieves lighter weight of products and reduces environmental pollution."
