At present, domestic private zinc alloy die casting enterprises generally have advanced equipment resources and advanced technology application. New technology can be widely and rapidly applied in industry. From design and manufacture to the production of related materials, heat treatment and so on, forming an industrial chain, has outstanding advantages. Integration. At present, due to insufficient funds and lack of independent brands, zinc alloy die casting enterprises will increase investment in management and technological transformation, expand the proportion of high-end products, and establish a domestic sales department to actively expand the domestic market.
With the increasingly fierce competition in the international die-casting zinc alloy market, Japan's die-casting aluminum alloy industry is also striving to reduce production costs. From the perspective of market size, Japan's economic recession is the most obvious, both in terms of output value and domestic demand. Japanese aluminium alloy die-casting manufacturers pay more attention to polishing and grinding technology, while German zinc alloy die-casting manufacturers start with improving processing accuracy and efficiency and reducing manual processing time. At present, Japan's aluminium alloy die-casting industry is gradually transforming its low-tech aluminium alloy die-casting into low-cost production in the region. Only high-tech products are produced in Japan. This trend of accelerating the transfer to foreign countries has reduced the use of die-casting aluminium alloys in Japan.
At present, there are many places where die castings are used. In view of this phenomenon, it is also very important to produce good aluminium alloy die castings. Following is a study on mould resistance of aluminium alloy die castings.
Now everyone is very picky, if the product has mildew, we directly use image products. In view of this phenomenon, our factory specializes in producing this product, looking for a good way to prevent mildew. After continuous research, we finally developed a method to prevent mould in die casting. The details are as follows.
First of all, attention should be paid to the use of slag containing sodium salt in the process of processing. Secondly, it is impossible to use a stripper consisting of plant fibers. It is better to replace the better quality release agent. It should also be noted that cutting fluids containing vegetable fibers should not be used, and oil-based cutting fluids should be used instead. If the products are best protected against dust accumulation on the surface, the products can not be stored in open air for a long time. If you accidentally touch water, you must ventilate and dry.
In recent years, the design level, technical parameters, performance indicators, mechanical structure and manufacturing quality of die-casting machine in China have been improved to varying degrees, especially cold chamber die-casting machine and hydraulic original car body turnover bonding mechanism, and automatic loading and spraying have been added. Automatic pickup, automatic trimming, etc. can also be controlled by ordinary electronic computer. Great progress has been made, some of which have reached or approached the international level and are developing towards large-scale, automation and modularization.
China is the world's second largest bauxite producer with an annual output of about 47 million tons. However, due to the deviation of ore quality, it is difficult to develop and smelt, which is not conducive to the production of alumina. As a result, China has long relied on imports. Australia is the world's largest bauxite producer with an annual output of about 81 million tons. Global supply is tightening. Strong growth in China's market demand is driving bauxite prices back up. The manufacturer hopes to fully start the spare capacity of bauxite smelting and aluminium alloy production, and then export high value-added aluminium products to overseas markets. There is no doubt that the demand for high-quality bauxite in the Chinese market is growing rapidly. With Indonesia and Malaysia restricting bauxite exports, Chinese bauxite refineries began to pay more attention to Australian bauxite, which has abundant reserves and unique quality advantages.
