As the world's largest supplier of turbocharged investment castings, Sinopei Digital Energy Powertrain Division is one of the main businesses of Sinopei Digital Energy at present and one of the main core business segments in the future
Process introduction
The investment casting process is capable of producing a wide range of complex workpieces and is suitable for almost all metal materials.
Its main features are as follows:
1. The dimensional accuracy of the casting is high and the surface roughness is small. The dimensional tolerance zone can meet the national standard CT4-CT6 class, or can meet the VDG-P690 standard D1-D3 class. The surface roughness can generally meet the requirements of Ra3.2-Ra6.3, and can be used directly without subsequent machining or only a small number of parts can be used to meet the use of
2. It can be applied to complex structural parts, or structures that are difficult to achieve or difficult to process by other processes, and the product weight is especially suitable for mass production castings
from a few g to a few kg 3. There are almost no restrictions on casting materials, especially for various high-melting alloys (various stainless steels, heat-resistant steels, high-temperature alloys, etc.) or various structures that are not easy to forge, weld or process

Process

Equipment capabilities
The reason why investment casting can become one of the near-net shape processes is inseparable from high-precision equipment, constant temperature and humidity workpiece environmental control, as well as engineers' mold design and manufacturing capabilities and gating system design capabilities. Our engineers ensure the high precision of the workpiece through high-quality equipment and strict process parameter control of each process
