The market share of light alloy die casting

    In developed countries, the market share of light alloy die casting is relatively high. With the increase of the die casting equipment and technology, more and more black metal castings are replaced by the nonferrous metals die castings, such as aluminum alloy and magnesium alloy. At present, the production and consumption of the die casting of the country is mainly the United States, China, Italy, Germany, Mexico, Japan, etc.. In developed countries die casting industry, individual enterprises of large scale, specialization degree is high, high degree of concentration, in the capital, technology, customer resources and has strong advantages, higher value-added products, the proportion of market share higher.

    Our country's pressure casting market share is in the stable growth phase. In the past ten years, the annual growth rate remained at 10%. The market share of high precision aluminum alloy die casting is higher, magnesium alloy die casting market share in the steady rise stage. Aluminum alloy, magnesium alloy and other light alloy die casting industry is the basic industry of national economic development, product application field is very extensive.

Design principle of die casting mold horizontal runner

    The structure and size of the die casting mold horizontal runner is determined by the structure, location, direction and the width of the inlet port.

    The cross-sectional area of the horizontal runner is greater than that the cross-sectional area of the ingate in any case. If it is multi-cavity mold, the cross-sectional area of the main runner should be greater than the sum of the cross-sectional area of the branch runner.

    The horizontal runner should have a certain thickness and length, to ensure the steady flow and the guiding role of liquid metal. The corner should take a circular arc. Too thin will cause the loss of heat, is not conducive to pressure transfer and repair. Too thick will increase the consumption of materials, reduce the production efficiency of die casting. In the die casting mold making, in order to save material and reduce the flow resistance, the horizontal runner should be as short as possible.

    From the straight runner end to the ingate, the cross section area of the horizontal runner should be maintain consistent or slow contraction, can not suddenly change, to prevent the negative pressure suction or package gas.

    Die casting mold for horizontal cold chamber die casting machine, in general, the horizontal runner entrance should be located at the top of the straight runner, to avoid the liquid metal in the pressure chamber into the mold cavity before injection.

How to develop metal stamping parts manufacturers

    Hardware stamping parts have become the future development opportunitie of hardware market. With the automatic lathe parts market competition pressure increases, most metal stamping parts manufacturers in the production, the different stages of the industrial chain of profits are to reduce, the price of space decreases with each passing day. According to the international mould and hardware plastic Suppliers Association survey found that, after price increases, increases the cost of hardware factory, if rely on their own to support, is difficult to transfer to the downstream, metal stamping parts supplier profits further squeezed. The industrial chain develops the vicious circle causes the multitudinous hardware factories realized that wants the long-time development, must choose the new market. At the same time, only by price competition can not establish the core competitiveness, this is not a long-term development direction, so to explore new development path. At the same time to strengthen the enterprise's own product technology innovation and quality improvement. To establish a new management principle, to ensure the sustainable development of enterprises.
