The impeller is the part of the mixer that imparts fluidity. Mixing impellers, also known as agitator blades, are designed to transfer motor-driven energy to the contents of the tank as quickly and efficiently as possible. There are four main types of mixing impellers, each type of mixing impeller converts the energy given to it in a different way

Stainless steel stirring impeller castings
Stainless steel alloys are widely used as materials for stirring impellers and have excellent corrosion resistance, thus minimizing contamination of the material being processed. The focus on purity in the food, dairy, beverage and pharmaceutical industries is reflected in the need for smooth surfaces, especially those in contact with the fluids used.

So how is the stainless steel stirring impeller made? From the types of stirring impellers, it can be seen that there are many different shapes, each of which has a different structure. To meet the various needs of stirring impellers, stainless steel lost wax casting, also known as stainless steel investment casting, is often used to manufacture stirring impellers.

 Stirring impeller stainless steel casting is a lost wax precision casting process in which the liquid metal is poured into the shell after the wax in the shell is melted. Through investment casting, our customers can obtain net shape stirring impellers with good surface finish, reducing or saving secondary machining. In addition, in order to obtain bright or more surface effects, the surface of the stirring impeller after casting of stainless steel can be mechanically or chemically treated or electropolished. Surface scale and discoloration that occurs after heat treatment can be removed by chemical treatment. For high purity requirements, electropolishing not only has the advantage of being versatile, but also provides a very smooth surface that is easy to passivate.
