The gas hole standard of aluminum alloy die casting stipulates the principle of grading and rating method of low porosity of aluminum alloy casts, which is applied to sand casting for aluminum alloy. It fits for the outer surface of the casting and the surface gas hole and pinholes after machining....

The main elements of zinc alloy are zinc and alloy, they are both amphoteric metals which have poor chemical stability, easily oxidize and corrode, so zinc alloy cast needs to be electroplated or coated. When it comes to those that don't require a lot of pressure and have complicated shapes, we...

We add a lot silicon into aluminum alloy for die casting. When aluminum alloy was condensed in the mold, silicon would float to the surface and form a thin layer of silicon film, which has high hardness and wear resistance. Some designers of OME (Original Equipment Manufacturer) use this feature to...

Aluminum alloy die casting is scraped because of pores existing. There are various of reasons causing pores. However, figuring out the product quality is quite difficult. How to quickly and correctly take measures for reducing rejection rate due to pores attracts attention from all of aluminum alloy...

At present, molds in China have short service life, high consumption. So, improving service life of mold has already become a priority. The surface treatment on mold has great influences on its service life. Most of damages on mold are caused by improper heat treatment. According to statistics, mold...

Metal die casting is an advanced technology with less or no cutting, having high production efficiency, few raw materials consumption, less production cost, good performance and high precision. Die casting is widely applied. Among that, the largest market of die castings is auto industry. For people...

Strut housing used on GT-R manufactured by Nissan is made by high vacuum die casting, improving excellent car body stiffness and controllability. The following are the processing of strut housing used for GT-R. 1. Feasibility of die casting. Strut housing on GT-R transfers 15 parts on strut and wheel...

The materials of die casting mold used for aluminum alloy should have good thermal conductivity and thermal fatigue resistance. The materials of die casting mold are not easily oxidized under high temperature, and can resist to adhesion of liquid metals, having lower coefficient of thermal expansion....

Pressure casting can cast complicated components having high precision, low surface roughness and good mechanical properties. Die casting mould should have the following performances. 1. High temperature strength and toughness Die casting mould may easily deform, even craze, when suffering from high...

Aluminum die casting has excellent mechanical and physical property. It has comprehensive property cooperating with different strength, hardness and toughness. It also has one or several particular performances, such as wearing resistance, high or low temperature resistance and corrosion resistance. ...

Using laser surface processing can improve the surface of low grade materials, combining low cost of components manufacturing and high performance of working surface, having considerable economic benefits and social benefits.  Laser hardening depends on heat conduction of material substrates realizing...

Requirements for die casting tendon design: Tendon is used to improve strength and rigidity of parts when reduce wall thickness in case of die casting shrinking and deforming. It also prevents work piece from deforming when the piece is ejected out from the mould. The tendon is also used to assist loop...
