With the intensification of competition in the home appliance industry, it requires us to try our best to reduce costs and enhance the price advantage of products in order to win more orders. In order to enhance the competitiveness of products, maintain a good profit margin and low cost, using plastic instead of metal and other traditional materials has become one of the main strategies of market product management.
Using plastic instead of metal has become a new trend in the development of household appliance materials. At present, the application of plastic instead of metal accounts for more than 15% of the total. The development of high-performance engineering plastics has broadened the application field of plastics replacing metals, and is widely used in automotive, electrical appliances, medical and other fields. The use of advanced design tools and the optimization of molding tools have promoted the application of plastic instead of metal. Plastic instead of metal has the characteristics of simple processing and molding, high utilization rate and high production efficiency. Wood molding has significant advantages, which is very suitable for batch continuous production.
According to relevant technical statistics, if plastic with equivalent performance is used to replace metal to produce the same part in electrical appliances, the material cost will be greatly saved. At the same time, metal parts often go through many processes, while engineering plastics only need one blister forming, and parts can be obtained in a short time, which greatly improves work efficiency and reduces energy consumption and processing costs.
At present, most TV sets are made of ABS engineering plastics. ABS resin is one of the five synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical performance. It also has the characteristics of easy processing, stable product size, good surface gloss and so on. It is convenient for coating and coloring. It can also be used for secondary processing such as surface spraying metal, electroplating, welding, hot pressing, bonding and so on. It is widely used in mechanical, automotive, electronic and electrical appliances, instrumentation, textile, construction and other industrial fields, It is a widely used thermoplastic engineering plastic. In addition, in some high-end TVs, carbon fiber and engineering plastic composites are usually used to increase aesthetics and reduce weight. However, due to the high cost, they have not been widely used at present.
The plastic shell of TV sets is produced by vacuum plastic absorption process, and the mold used is metal aluminum plastic absorption mold. The mold cost is low, which is generally thousands of yuan, while the metal shell of TV sets is stamping process up and down, and the metal mold is used, which has high mold cost. The general mold cost is tens of thousands or hundreds of thousands of yuan. Therefore, from the perspective of mold cost, the blister process is much lower than the stamping process.
In short, the plastic shell used for TV shell has the advantages of light weight, good hand feel, good insulation, low cost, short production cycle, no electrostatic shielding and so on.
