Metal die casting process is a high-precision high-pressure metal casting process is a precision casting method. In 1964, the Japan Die Casting Association defined die casting as a method of producing high-precision casting surfaces with high precision in a short period of time. The United States says die-casting is die-casting, and the UK is said to be die-casting die-casting pressure, while the familiar general domestic industry is Japan’s saying that it is called die-casting. The castings produced by the die casting process are called die castings.
Metal die-casting processing is a casting method for precision casting, the dimensional tolerance is very small made of castings, the surface accuracy is very high, in most cases the castings are not re-turned for assembly applications, threaded parts can be cast out directly. From general camera parts to typing parts, small parts such as electronic calculators and accessories, as well as transportation tools for complex parts such as automobiles, motorcycles, and airplanes, most of them are manufactured by die-casting.
These materials have almost twice the tensile strength of common cast alloys. It has a more positive impact on the production of aluminum alloy wheel frames, etc. 2 Die casting is a casting method that integrates liquid gold into the cavity, and fills the mold at high speed to solidify the liquid alloy under pressure. Die casting is distinguished from other casting methods by high pressure and high speed.
The molten metal fills the cavity under pressure and crystallizes and solidifies under high pressure. The common pressure is 15-100mpa.
The liquid metal filling the mold cavity at a high speed is usually 10 – 50 m/s and some can exceed 80 m/s, so the filling time of the molten metal is very short, about 0.01 to 0.2 seconds. Die casting machine, die casting alloy and die casting mold are the three main factors in die casting production. The three elements of the casting process are organically combined to make stable rhythm and high-efficiency production of appearance and inner quality, and good dimensions meet the requirements of qualified casting drawings or agreements for higher-quality castings.
Electricians are everywhere in modern society. News about electrical processing, bicycle die-casting accessories, mobile phone mid-plate die-casting, radiator processing, mechanical parts processing, mechanical parts die-casting, electronic parts die-casting, and aluminum alloy die-casting parts processing. Die-casting molds are a large category of molds. With the rapid development of China’s automobile and motorcycle industries, the die-casting industry has ushered in a new period of development. At the same time, higher requirements are put forward for the mechanical properties and life of the die-casting mold. In order to meet the increase in performance requirements, it is still difficult to rely on new mold…
For precision parts, the processing is very strict, and the processing procedures include cutting in and out. There are specific requirements for the size and accuracy, such as how many microns are plus or minus for 1 mm, etc. If the size is too wrong, it will become a waste product. At this time, it is equivalent to reprocessing, which is time-consuming and laborious, and sometimes even makes the entire processing material scrapped. This has just caused the increase of cost, and at the same time, the parts are definitely unusable. The processing of precision parts is mainly based on…
The design knowledge base of the aluminum alloy low-pressure casting system adopts the idea of modularization. According to the functions of the system, three sub-modules of the Dongguan die-casting knowledge base are designed, namely, the explicit knowledge module, the three-dimensional module, the rule knowledge module. The ultimate goal is the low-pressure casting process KBE system aluminum alloy to obtain more detailed cards, so the design of the database will require a stored process involving explicit knowledge, so the establishment of explicit knowledge modules is to facilitate management and calling, combined with knowledge acquisition Mechanism, explicit knowledge is divided into different…
In recent years, there are more and more alloy die-casting manufacturers. In the era of rapid technological development, mechanical equipment is also constantly being updated. There are more and more situations where mechanical castings are in short supply, so there are so many die-casting manufacturers. Defects are mainly protruding vesicles on the surface of the mold. Polished or machined to expose after fuel injection or plating. The cause of foaming defects in castings is that the pores are mainly caused by pores and shrinkage mechanisms, and the pores are often circular and shrink irregularly. The cause of the porosity is…
Everyone knows that the quality of alloy parts produced by alloy die-casting manufacturers has a great relationship with die-casting molds, so the maintenance of molds is very important. The molds affect the precision of die-casting tools. Good molds can produce good Die-casting parts, let me introduce the relevant information about the maintenance of die-casting molds. That is to set up a complete set of records for each set of molds in the factory. This is guaranteed after maintenance and maintenance is an important basis for each to be done in detail, including production patterns once a day. As the management…
