Consumption and export investment is the driving force for the development of China's casting industry---BL Die Casting Investment, consumption, and export are the three troikas that drive economic growth. The above three major forces are also extremely important for the development of the casting industry. Consumption is internal demand, that is, the consumption capacity of domestic castings; export is external demand, that is, the demand of China's castings in the international market; investment mainly refers to capital expenditure. For a long time, China's casting industry relies on the development of the above three major powers, but there is an imbalance in the proportion of various powers. At present, in the process of development of China's casting industry, there are drawbacks of excessive dependence on investment and export power. The huge scale of China's casting industry comes from, which is mainly dependent on investment expansion, so that China's casting production scale has rapidly climbed to the top in the world in just a few decades. In addition, the product consumption channels of a large number of casting production enterprises in China are mainly exported. This aspect is determined by the huge production capacity of castings in China and the lack of consumption space in the domestic market. On the other hand, the casting production enterprises in China have long neglected the development of the domestic market. . China's casting industry relies too much on investment and exports to drive industry growth. Once the economic cold is encountered, domestic casting enterprises will be affected by a large area, leading to the lack of success of the company and even the collapse of the economic cold wave.

2022 / 09 / 01
In recent years, with the rapid development of the manufacturing industry, the precision of processing and manufacturing parts and products has been continuously improved, especially in the processing of important holes on some large parts, which have high requirements for shape, position, dimensional accuracy and surface roughness. Under the conditions of mass production, it is necessary to take certain measures on the tool and processing technology to meet the design requirements of the pattern. First, the issue of the problem When processing the fan motor seat, the processing of the two positioning pin holes on the machine base is always unqualified. The equipment used by the company is the CNC TK6920 milling and boring machine produced by Qier Machine Tool Plant. The machine tool has no cutting fluid supply system. Most of the tools are domestically produced common cutting tools, such as twist drills, ordinary reamers, and some use Sandvik Coromant tools. When machining the pin hole, the process we use is: drilling the center hole → drilling → reaming → reaming. The drilling and expansion process uses a common twist drill, and the hinge uses a domestically used reamer. These tools are connected to the holder by a drill sleeve (reducing sleeve).
New technology for surface treatment of die casting mold
2022 / 08 / 19
As a kind of mold strengthening technology, the coating technology is mainly applied to the surface treatment of molds with relatively simple working conditions such as plastic molds, glass molds, rubber molds and stamping molds. Die-casting molds need to withstand the harsh environment where the thermal and thermal stresses alternate, so coating technology is generally not used to strengthen the surface of the die-casting mold. Die casting molds are a large class in the mold. With the rapid development of China's automobile and motorcycle industry, the die-casting industry has ushered in a new era of development. At the same time, it also puts forward higher requirements on the mechanical function and life of the integrated casting die. It is still difficult to meet the needs of the continuous use of new mold materials. It is necessary to apply various surface treatment techniques to the surface treatment of die-casting molds in order to achieve high efficiency, high precision and longevity of die-casting molds. . Among various molds, the working conditions of the die-casting mold are relatively harsh. Pressure forging is to make the molten metal fill the mold cavity under high pressure and high speed and die-casting. It is repeatedly contacted with hot metal during the working process. Therefore, the die-casting mold is required to have high heat-resistance, thermal conductivity, wear resistance and corrosion resistance. Properties, impact toughness, red hardness, good release properties, etc. Therefore, the surface treatment technology of die-casting molds is relatively high. In recent years, various new techniques for surface treatment of die-casting molds have emerged, but in general they can be divided into the following three categories: (1) Improvement techniques of traditional heat treatment processes; (2) Surface modification technology, including surface thermal diffusion treatment, surface phase transformation strengthening, electric spark strengthening
Technical characteristics of high pressure die casting of metal aluminum
2022 / 08 / 12
Aluminum, a silver-white light metal, ranks 13th in the periodic table and has good ductility. The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third, and is a rich metal element in the earth's crust. It is an important metal material in industrial production. Because of its low melting point and good ductility, it is a metal material that is frequently used in the die casting industry. Aluminum is a very important metal manufacturing because of its versatility and the variety of applications of both treated metals and their alloys in different industries. High-pressure die-casting faster route makes the molten metal the finished component. This can be removed by injecting the molten metal into a hard steel mold, tool, and allowing it to cool and solidify pressure before it is removed. This process provides an accurate, rapid, low-cost production method for aluminum and zinc die castings, meeting the needs of the high-tech industry where the appearance and dimensional tolerances of the product are critical and the volume is not always large. Aluminum is a high-pressure die-cast aluminum metal used in the process and is a metal alloy that has many advantages and is suitable for casting applications. Many of these reasons are due to the nature of the metal used in aluminum die casting processes. Aluminum has many characteristics that are very suitable for this process. Aluminum is very light and highly tough and can easily be defeated into different shapes and sizes depending on demand. It is also very malleable and has good dimensional stability allowing it to realize complex shapes and thin-walled parts.

How to distinguish between die-casting and die-casting forging
2022 / 04 / 13
1. Differentiating the meaning of the pressure casting and die casting (liquid forging) parts: 1, is a number of domestic agencies, including parts and the entire manufacturer. They undertake external parts and components, and then find some manufacturers in the country. Since the production processes of the two blanks are different, the current market price is not the same, and the latter is generally higher than the former. If you do not distinguish between the two types of roughs, if you press down on the casting at a low price when undertaking business quotation, there will be operational mistakes, which will affect the efficiency and even loss. 2, is a professional manufacturer of castings and forgings. Because the latter is die-casting, it can be manufactured using traditional die-casting technology and the business can be taken over. After the die-casting mold was opened, the billet produced by the die-casting process finally had a shrinkage shrinkage defect or an appearance defect, and the blank was unqualified, eventually causing undue loss. 2. The relationship between die forging, liquid forging and continuous casting and forging processes: The essence of the continuous casting and forging process is the continuous completion of casting styling and forging in a single set of tools on a single machine. The continuous casting and forging process is not a new process, and its principle has a long history. The most typical and simplest continuous casting and forging process is the familiar liquid forging (melt forging) process. The die-casting and forging process, graphically speaking, is a kind of specialized equipment that uses a higher degree of automation to produce liquid forgings that are as complex as ordinary die castings. Because of this, die-casting forgings and ordinary die-castings are not easy to separate in appearance. The quality of the blank produced by the continuous casting and forging

Method for improving service life of die casting mould
2022 / 03 / 22
Method for improving service life of die casting mould Due to the long production cycle, large investment, and high manufacturing precision, die-casting molds have a high cost, so it is hoped that the molds will have a higher service life. However, due to the influence of a series of internal and external factors such as materials and mechanical processing, the molds are prematurely invalidated and scrapped, resulting in great waste. The failure modes of die-casting molds are: sharp corners, corner cracking, splitting, hot cracking (cracking), wear, and erosion. The main causes of die-casting mold failure are: defects in the material itself, processing, use, maintenance and heat treatment. First, the material itself has defects It is well known that the conditions of use of die-casting molds are extremely harsh. Taking aluminum die casting as an example, the melting point of aluminum is 580-740°C. When used, the temperature of aluminum liquid is controlled at 650-720°C. In the case of die casting without preheating of the mold, the surface temperature of the cavity rises from room temperature to the liquid temperature, and the surface of the cavity is subjected to a great tensile stress. When molding the top piece, the cavity surface is subjected to great compressive stress. Thousands of die castings have cracks and other defects on the mold surface. It can be seen that the conditions for die-casting are quenching. Mold materials should use hot and cold fatigue resistance, fracture toughness, high thermal stability of the hot die steel. H13 (4Cr5MoV1Si) is currently widely used materials, according to reports, 80% of foreign cavity H13 are used, and now the country is still heavily used 3Cr2W8V, but 3Cr2W8VT_art performance is not good, poor thermal conductivity, high linear expansion coefficient, The work generates
Good prospects for development in aluminum machinery area
2022 / 03 / 22
According to the statistical data of industrial enterprises and the analysis of related national statistical data, the total output value of the machinery general parts industry in the first quarter of 2022 was 136 billion yuan, a year-on-year increase of 5.8%. Among them, the four professional developments of gears, springs, powder metallurgy, and transmission couplings are in good conditions, and the development of the two fasteners and chains is relatively weak. The general machinery spare parts industry was driven by the development of host equipment such as automotive equipment, rail transportation, aerospace, marine vessels, and robot manufacturing. The industry achieved relatively stable development. The supporting enterprises that have relatively close contact with the above-mentioned well-developed host equipment industry can basically meet their production requirements in September, while the orders for general enterprises are less. On the other hand, there are plenty of product orders for companies with strong corporate brand influence, early structural transformation and upgrading, and stable product quality. However, the general corporate product orders have a weak development momentum. The import and export of the industry showed a relatively strong development. The total value of imports and exports reached 16.25 billion U.S. dollars, a year-on-year increase of 14.9%. The total industry import volume was 9.798 billion U.S. dollars, an increase of 17.3% year-on-year; the total export volume was 6.453 billion U.S. dollars, an increase of 11.3% year-on-year, both of which achieved double-digit growth. The increase in imports was mainly driven by the significant increase in the volume of various gearbox imports in the gear industry. In the first half of the year, the import volume of gears was US$7.41 billion, an increase of 19.5% year-on-year, and accounted for 75.6 of the total import value of the industry. %; Professional imports
