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 materials. Various surface treatment technologies must be applied to casting molds. Die-casting molds can achieve surface treatment with high efficiency, high precision, and long life requirements. Die casting is a process in which high-pressure, high-speed full-mode and die-casting molten metal are in repeated contact with hot metal, so die-casting molds have high heat resistance, thermal fatigue wear, corrosion resistance, impact toughness, red hardness, Good mold release, etc. Therefore, technical requirements for die-casting mold surface treatment In recent years, various new technologies for die-casting mold surface treatment have emerged, but they can generally be divided into the following three categories:
Improvement of Traditional Heat Treatment Process
The traditional heat treatment process of die casting mold is quenching and tempering. Since various materials can be used as die-casting molds, the application of the same surface treatment process and process in different materials will have different effects. SKOV recently proposed the base material pretreatment technology for the mold base material and surface treatment technology, and the treatment technology proposed different mold materials on the basis of traditional techniques to improve the performance of the mold and increase the life of the mold. Another development direction of heat treatment technology is to combine traditional heat treatment technology with advanced surface treatment technology to improve the service life of die-casting molds. If the carbonitriding chemical treatment method is combined with the conventional quenching and tempering process (that is, carbonitriding carbonitriding quenching) NQN composite strengthening, not only has a high surface hardness and an increase in the depth of the effective hardened layer, the layer hardness gradient The distribution, stability and fire and corrosion resistance are improved in order to obtain good performance cores at the same time, greatly improving performance and surface quality.

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…
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…
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…
