Welding process: When the manifold is composed of multiple components, welding is a critical process. For example, some large and complex industrial manifolds may first be processed into several small components, and then connected into a complete manifold by welding. To ensure that the sealing and strength of the welds meet the use standards, advanced welding technologies such as argon arc welding and laser welding are often used to ensure welding quality.

Plasma cutting (plasma arc cutting): Plasma cutting plays an important role in manifold manufacturing. It can quickly and accurately cut metal materials, whether stainless steel or aluminum alloy. Through plasma cutting, parts that meet the design shape of the manifold can be obtained, providing a high-quality parts foundation for subsequent welding and assembly processes, and improving overall production efficiency.

Casting process: If the manifold is manufactured by casting, such as sand casting, the corresponding sand mold will be made according to the designed model, and the molten metal liquid (such as aluminum alloy liquid) will be poured into the sand mold. After cooling and solidification, the blank will be taken out, and then the preliminary manifold product will be obtained through cleaning, polishing and other processes. For some manifolds with complex shapes and many irregular flow channels inside, casting is a more suitable process, which can better form the required shape.
