About New Energy Automobile Die Casting Parts

Sieg-Huao, a professional supplier of high pressure die casting and investment casting has developed die casting parts for new energy car from several years ago. It is a trend of development due to the requirements of automobile lightweight. Today we will share with you some technical common senses about the new energy cars die casting parts.

During the processing of new energy automobile die casting parts, the parting surface, cavity and top lever should be cleaned. The coating materials need to be changed and spraying technology need to be improved. And also the ability of locking mold and the pouring metal component shall be strengthened.

During the processing of new energy automobile die casting parts, it is necessary to adjust that parameter of the treatment technology, the projective power, the time of injection, the filling time of the mold, the opening time of the mold, the pouring temperature and the mold temperature.

The replacement principle of the new energy automobile die casting is to select the aluminum alloy ingot material with excellent quality, to improve the new principle and the converter principle and improve the smelting processing skills.

Now we will introduce the defect characteristics of new energy automobile die casting parts. All of these below defects can be seen by appearance inspection. On the surface of the casting, there are striations in line with the flow direction of metal liquid, and there are obviously non-directional veins which are different from the color of metal matrix and have no development trend. The surface of die casting pieces has the appearance of network hairline like protruding or concave marks, expanding and extending with the increase of die casting times. When the casting is placed in an alkaline solution, the crack appears as a dark gray metal matrix with a straight line or wave shape, narrow and long lines. Under the action of external forces, the crack tends to be penetrating and non-penetrating.

New energy automobile die casting products have been widely used in the field of automobile as the center due to their high precision in size, good casting aesthetics and excellent mass production performance. In order to manufacture more quality die casting products, more extensive products will be designed in the future, which requires advanced mould technology and casting technology, as well as high performance die casting machines.
