Depending on the perfect quality monitoring system, we can provide customers with a coordinated service of R&D, manufacturing and production.

Mechanical properties of dies
The mechanical properties of dies require that the properties of die materials are determined by the composition of die materials and the structure after heat treatment. The basic structure of die steel is composed of martensite matrix, carbides and intermetallic compounds distributed on the matrix.
Matters needing attention in choosing raw materials for die casting processing
Die-casting industry is the most important type of processing technology in modern heavy processing industry. Therefore, China is increasing the strict control of die-casting processing enterprises, including strict management of product standards and processing technology. The selection of raw materials for die castings plays a key role in processing. Because the die casting die processing can not avoid some external forces such as impact, vibration, friction and so on. So it is necessary that those materials can support these external forces without being damaged. Therefore, the material requirements for die casting die processing are necessary. Among them, the most important requirements are the requirements of blanking die materials, drawing die materials and cold extrusion die materials. The first point is that the requirements of blanking die materials are mainly for the use of blanking dies with thinner plates, which should be paid attention to the use of higher wear resistance and hardness performance; the second type of deep drawing dies for die casting raw materials is that the raw materials should have a higher non-adhesiveness and non-adsorption. The third kind of requirements for cold extrusion raw materials for die castings mainly focus on whether the raw materials have high hardness and high heat resistance. Only the raw materials of die castings that meet these conditions can produce really high quality die castings. Therefore, when choosing the raw materials of die castings, we must pay attention to these basic selection principles.
Flange connection mode
Flange connection is to fix two pipes, fittings or equipment on a flange separately, between the two flanges, plus flange pad, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection. Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. In industrial pipelines, in the family, the diameter of the pipeline is small, and it is low pressure, so the flange connection can not be seen. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
According to the type of flange connection, flange connection can be divided into: plate flange, necked flange, butt-welding flange, socket flange, thread flange, flange cover, necked butt-welding ring flange, flange cover, flange flange flange flange, flange flange flange flange flange, flange flange flange flange and groove flange, large-diameter flat flange, large-diameter high-neck flange, eight-word blindness. Slab, butt welded ring flange, etc.
