Copper die casting machine and lamp die casting machine are essential industrial equipment for precision metal and lamp part manufacturing, widely used in mass production of complex die-casting components. Understanding their strengths and limitations helps manufacturers optimize production and equipment selection. These two types of die casting machines deliver prominent production advantages. They can form complex thin-walled metal parts with clear outlines, thanks to the high fluidity of molten metal under high pressure and high speed, realizing processing effects that traditional methods cannot achieve. The finished die castings feature high dimensional accuracy of IT11-13 (up to IT9) and fine surface roughness of Ra0.8~3.2um, with excellent interchangeability. In addition, the equipment boasts high material utilization of 60% to 80% and a blank utilization rate up to 90%, greatly reducing material waste. With fast filling and rapid metal condensation, the die-casting cycle is short, ensuring high production efficiency ideal for mass production. It also supports insert casting to meet customized local performance requirements of workpieces. However, the equipment has certain limitations. Rapid filling and cooling easily leave pores and oxide inclusions in castings, making heat treatment unavailable. High costs of machines and molds are not suitable for small-batch production. Restricted by mold size and clamping force, it cannot produce extra-large castings, and only adapts to limited alloy types including copper, aluminum, zinc and magnesium alloys.

The development of everything has its own law of development, and the hardware market is no exception. The development of my country's hardware market first benefits from the development of my country's economy and the rapid development of my country's hardware industry. Luo Baihui, secretary general of the International Association of Mold and Metal Plastic Industry Suppliers, said that my country's hardware manufacturing industry is already the manufacturing base of the world's hardware industry, and its production share accounts for more than half of the world's hardware manufacturing. my country's hardware manufacturing industry is in a stage of rapid expansion. This market situation has laid the foundation for the development of the national hardware market, but as far as a specific hardware market is concerned, it is essential to do the following three aspects if you want to become bigger and stronger. The hardware manufacturing industry must achieve these three points to be strong First, adopt a differentiated business strategy. The division of branches, market segmentation, and the formation of specialized and large-scale markets are the primary guarantees for market prosperity. Take the North China Hardware City as an example. At the beginning of the market’s formation, the hardware market in Tianjin was dominated by Lao Nanma Road Hardware City before 2005. Due to historical factors, it is located in the bustling downtown area. According to the characteristics of the hardware market, we believe that the hardware market The market is unlikely to be entrenched in the downtown area for a long time. After reviewing the overall urban planning of Tianjin, the site was chosen to be close to the outer ring line and the 205 National Road. The new district can radiate far to Beijing, the three northeastern provinces, Hebei province and other places, and it is the first choice for the market. However, as how the emerging hardware city complements the old city and gradually strengthens itself, we have chosen a differentiated complementation strategy. In 2006, we began to make a unified business positioning and positioning for the current four districts of A, B, C, and D. According to the plan, Area A and B are hardware and electrical appliances area, Area C is solar energy area, and Area D is pipeline valve area. In the later investment promotion, many construction machinery and machine tool equipment operators think that our city’s buildings are spacious and have relatively high floors. The roads are wide, suitable for large-scale equipment to enter and exit, and one after another enters the city for operation. We have opened up a professional street for machinery and equipment in a street on the west side of District A and C in accordance with the requirements of the market. This makes the business planning of the four districts comparable to other hardware markets in Tianjin. The positioning of the company is differentiated, and the effect of se...

Sometimes there are customers consulting the gravity die casting machine, but did you know? In fact, there is no such thing as a gravity die casting machine. There are only two machines, a gravity casting machine and a die casting machine. (Gravity casting machine is also called gravity casting machine, also written as "casting machine") The two machines are completely different , Bengbu Longhua Die Casting Machine will introduce to you their differences. The casting principle adopted by the gravity casting machine is the gravity casting principle：which is a casting process that relies on the earth's gravity to make the aluminum liquid flow into the mold. There are also centrifugal casting processes, which also belong to the scope of gravity casting. Gravity casting machines are usually used when producing parts with complex internal shapes. The die casting machine adopts the principle of pressure casting：that is, the molten metal is poured into the pressure chamber by mechanical force, and then the pressure is formed by the linear movement of the injection rod and the injection head, forcing the molten aluminum to fill the mold. Generally, die casting machines are used when the shape of the casting is complicated but the internal structure is relatively simple.  Bengbu Longhua Die Casting Machine has focused on casting production for 38 years. If you need it, please contact Bengbu Longhua.

Due to the fast running speed, high clamping force and frequent work of the die-casting machine, the related parts of the column frame of the die-casting machine may become loose, and the assembly accuracy will gradually change, which cannot meet the working requirements of the die-casting machine. The column frame must be adjusted every six months. Some related parts are adjusted and tightened to prevent loosening.   1. Adjust the parallelism of the working surface of the movable seat plate The parallelism of the working surface of the dynamic setting seat plate is an important technical indicator to measure the working performance of the die casting machine. If the parallelism error is too large, it will seriously affect the normal operation and product quality of the die casting machine, and there may be flying materials and products. The flash edge is large, and it may even be broken due to uneven force on the pillar.    2. Adjust the sliding feet of the middle plate   The design of the sliding foot of the middle plate is to support part of the weight of the middle plate on the steel belt, reducing the weight of the middle plate borne by the coring column, thereby reducing the wear of the middle plate copper division and the coring column, and extending its service life. The adjustment of the sliding foot of the middle board should be properly tight. When the adjustment is too loose, the sliding foot will lose its proper function. When the adjustment is too tight, the friction resistance will increase significantly, which will seriously affect the mold opening and clamping movement.   3. Regularly tighten the connecting screws of the thimble cylinder    The thimble cylinder has a lot of work times, especially when the working pressure of the cylinder is set too high, the installation screws may loosen, and need to be checked regularly, and tightened in time when loosened.
