Nowadays, household appliances are gradually becoming larger, and the “multi-cavity†developed in order to improve their production efficiency has also led to the increasing size of
home appliance molds . At the same time, the rapid development of home appliances and electronics has also brought about the miniaturization of parts. Precision, some molds have a machining tolerance of less than 1μm. Therefore, it is necessary to actively adopt advanced equipment and improve the level of mold manufacturing in order to achieve significant economic benefits. Let's take a look at the five advanced manufacturing technologies for home appliance molds:
1. Widely used high-speed machining technology
High-speed machining, generally used for large-scale home appliance cover molds, its surface machining accuracy can reach 0.01mm. After high-speed milling, the mold surface can be used with only a little polishing, saving a lot of grinding and polishing time. High-speed machining significantly shortens the molding cycle, thereby increasing the market competitiveness of the product.
2. High-speed scanner and mold scanning system
High-speed scanners and mold scanning systems provide the functionality needed to scan from model or physical to the desired model, dramatically reducing mold development and manufacturing cycles.
Some fast scanning systems can be quickly installed on existing CNC milling machine machining centers to achieve fast data acquisition, automatic generation of various CNC system processing programs, CAD data in different formats, and reverse engineering for mold manufacturing.
The mold scanning system has been successfully applied in industries such as Europe and the United States. In this respect, such as the high-speed scanner (CYCLON SERIES2) from Renishaw, the scanner can complement the advantages of laser probe and contact probe. The laser scanning accuracy is 0.05mm, and the contact probe has high scanning accuracy. 0.02mm.
3. Further development of hot runners and gas-assisted molds
More than 80% of the plastic molds produced by many foreign plastic mold factories use hot runner technology, and the effect is very obvious.
Many companies in Europe and the United States have been able to successfully use gas-assisted technology on TV casings, washing machine casings, and molds for thick-walled plastic parts. Gas-assisted injection molding has the advantages of low injection pressure, small warpage of the product, good surface quality, and easy to form a product with a large difference in wall thickness, which can greatly reduce the cost under the premise of ensuring product quality.
4. Combination of rapid prototyping technology and rapid molding technology
The competition in the home appliance market is increasingly fierce, and product renewals are accelerating. The combination of rapid prototyping technology and rapid tooling technology is applied to mold manufacturing, that is, the prototype of product parts is manufactured by rapid prototyping technology, and the mold is quickly manufactured based on the prototype. The application of RP and RT technology from mold design to manufacturing is only about 1/3 and 1/4 of the cost of traditional processing and cost.
Many home appliance manufacturers in Europe and America use rapid prototyping of silicone rubber molds for a small amount of plastic parts, which is very suitable for trial production. Some countries in Europe and America also use aluminum to make injection molds, which can shorten the injection cycle by 25-30%, greatly reducing the weight of the mold and shortening the grinding and polishing time by half. Germany has developed a reinforced plastic for the cavity and core of plastic molds with a life of more than 100,000 pieces. At the European Mould Show, rapid prototyping technology and rapid prototyping technology occupy a prominent position, with various types of rapid prototyping equipment such as SLA, SLS, FDM and LOM, as well as organizations and companies specializing in prototyping services.
5. High-quality mold materials and advanced surface treatment technology
The development trend of mold steel in Europe and America is that carbon tool steel, low alloy tool steel and high alloy tool steel have successively appeared a series of new mold materials, and the alloying degree of mold standard steel is also increasing. For example, in the United States, 15 kinds of hot work die steel alloy elements are all greater than 5%, while alloy elements greater than 10% have 10 kinds, the amount accounts for 80%.
