Die casting is a process of filling molten metal into a mold cavity under high speed and high pressure, cooling, solidification and precision machining to obtain castings with specified shape, size and properties. As an advanced non-ferrous alloy precision parts forming technology, die casting has the advantages of high precision, light weight, beautiful appearance, energy saving, high efficiency and low consumption. Meet the needs of modern manufacturing industry for product improvement, weight reduction, energy saving and greening. Therefore, die castings are widely used in automobile, household appliances, electronics, machinery and many other industries.
The raw materials used for die casting are different. Die casting products are divided into aluminum alloy casting, magnesium alloy casting, zinc alloy casting, copper alloy casting and so on. Among them, Aluminum Die Casting are easy to use and have high wear resistance, so they have high mechanical strength, excellent heat transfer and conductivity, and can withstand high temperature. It is widely used in household appliances, automobiles, electronic equipment, office equipment and machines.
(1) Scale and financial obstacles
As an industry with abundant capital, die casting industry has large investment in fixed assets, long construction period, long construction recovery period and high investment cost. This requires the company to have a high level of capital and invest a lot of money in factory construction and equipment procurement. In the fierce market competition of die casting industry, only enterprises with strong cost control ability, technology research and development ability and scale advantage can survive.
(2) Technical and quality barriers
As a technology-intensive industry, die-casting industry has very strict requirements for many processes such as dies, die-casting equipment and processes, and precision machining in the production process of casting products. In addition, downstream customers (for example, clean power, automobile manufacturers) increasingly need the material properties, shape, machining accuracy, weight and so on of products. We can effectively improve the material research ability of casting technology and processing technology, mature casting technology, high mold development and manufacturing level, and timely product difference.
(3) Market access barriers
Traditional die-casting industry is a chaotic competition with high cobblestone mixing, and there are many small die-casting companies in the market.
