About Solenoid Valve
Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design.
Generally, a complete solenoid valve consists of several components, including: valve body/housing, valve cover, coils, diaphram, plunger, fixing nuts, etc. Among them, some of critical components are designed and made in metal, especially stainless steel. For those stainless steel solenoid valve body and cover, they are usually produced by stainless steel investment casting.
Why Stainless Steel Casting for Solenoid Valve Components?
Stainless steel casting is a centuries-old investment casting process that centers around lost-wax casting. It involves coating a wax mold with a liquid material. As the wax heats up, it begins to melt off. Molten metal is then poured into the mold’s cavity, essentially replacing the cavity’s wax with metal. Finally, the metal is allowed to cool, after which it’s separated and removed from the mold.
It’s called “stainless steel investment casting” because the mold pattern used in this casting process becomes “invested” with the liquid refractory material. While other casting processes simply involve pouring liquid material into the mold’s cavity, stainless steel casting goes one step further by surrounding the mold with the liquid material. During this initial step, the mold becomes “invested” with the liquid refractory material.
Stainless steel casting for solenoid valve components offers several noteworthy benefits. Because it involves coating the mold with a liquid refractory material, it’s able to create solenoid valve components with an excellent surface finish. Additionally, with stainless steel casting, it can prevent solenoid valve components from rusting and corrosion. Stainless steel casting is considered a highly efficient process, as it creates minimal waste when compared to other metal forming processes.
