In V-casting, the molten metal needs to gradually fill the entire V-shaped mold starting from the injection port. The flow and filling process of the molten metal involves physical phenomena such as fluid mechanics and heat conduction. It is necessary to optimize the flow properties through simulation and experimental research to ensure the filling quality of the casting. V-casting is a complex process involving the control of multiple parameters and variables.

The vacuum joint 13 can be used in conjunction with the robot arm 12 to achieve automated box vacuuming operations. This can reduce manual intervention and improve production efficiency. The use of the vacuum joint 13 can quickly and efficiently extract the air in the box, saving the time and labor costs of manual operation. The vacuum joint 13 can adjust the vacuuming force and time as needed to achieve precise control of the air pressure inside the box. This is very important for some processes or products that have high requirements for air pressure.
