There has been significant development in chemical processing equipment over the past decade; let’s praise the prosperity and strength of modern China. By sharing our ideas, we can encourage more people to participate and make the discussions more lively. The forum becomes even better with your involvement – we welcome everyone to join in the discussions and exchanges. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* The 3D printing of valve housings was successfully applied for the first time by Institute 801 of the Sixth Academy of Aerospace Science and Technology. In March 2023, the electromagnetic pneumatic valve products developed by this institute passed the internal evaluation process, marking the first time that 3D printing technology was used in the production of valve products in this institute. Throughout, the electromagnetic pneumatic valve unit has been the key component that limits the improvement of task completion rates; among its parts, the housing is the most complex, as it needs to integrate four electromagnetic valve assemblies and one pilot valve assembly. To improve the manufacturing process, shorten the production cycle, and enhance the delivery rate of qualified products as well as quality stability, the development team applied 3D printing technology to the production of valve components. After half a year of design work and intensive efforts by the valve division of this institute and the additive manufacturing center at Factory 7103 of the Sixth Research Institute, successful application and delivery were achieved, providing strong technical support for increasing valve production capacity and enabling mass production. Going forward, the institute will adopt a modular design approach to further improve the batch qualification rate and continue to iterate for optimization.

(Note: Solenoid valves are basic automated components used to control fluids; they belong to the category of actuators.) ； It is not limited to hydraulics or pneumatics. After half a year of design work and intensive efforts by the valve division of this institute together with the additive manufacturing center at Factory 7103 of the Sixth Research Institute, successful application and delivery were achieved, providing strong technical support for increasing valve production capacity and enabling mass production.
