The high-pressure multi-path valve block utilizes sand mold 3D printing technology and is cast in A356 aluminum alloy. It incorporates multiple internal high-pressure flow channels. By printing both the sand molds and cores, the internal sand cores form the interconnected flow passages of the valve block, including hollow channels that communicate with one another. The sand cores are printed integrally, enhancing both the overall precision of the castings and core assembly efficiency.
The casting process developed by Simons' technical team effectively improves sand core venting performance, reducing the formation of gas pores in the internal flow channels. As the sand cores are manufactured as single printed components without assembly requirements, the installation and operation of the system become more convenient and efficient, thereby better supporting industrial-scale production.
