Why do stainless steel food machinery accessories use precision casting technology

Stainless steel precision casting generally contains small amounts of silicon, manganese, sulfur, and phosphorus in addition to carbon. Carbon steel can be divided into three types according to its purpose: carbon structural steel, carbon tool steel, and free cutting structural steel. Carbon structural steel is further divided into two types: building structural steel and machine manufacturing structural steel. The mold used for stamping is called a stamping die, abbreviated as a punching die. Stamping die is a specialized tool that processes materials (metal or non-metal) in bulk into the required stamping parts. Stamping dies are crucial in stamping, and without qualified dies, mass stamping production becomes difficult. Without advanced stamping dies, advanced stamping processes cannot be achieved. Today, we will talk about why precision casting is commonly used in stainless steel casting.

Advantages of stainless steel investment casting:

1.Due to the high dimensional accuracy and surface smoothness of investment casting, mechanical processing work can be reduced. Only a small amount of machining allowance can be left in the parts with higher requirements. Some castings only have grinding and polishing allowance and can be used without mechanical processing. It can be seen from this that using investment casting method can greatly save machine equipment and processing time, and greatly save metal raw materials.

2.Investment casting can cast complex castings of various alloys, especially high-temperature alloy castings. For example, stainless steel food machinery accessories, their streamlined outer profile and cooling inner cavity are almost impossible to form using mechanical processing technology. Production using investment casting technology can not only achieve mass production, ensuring the consistency of castings, but also avoid stress concentration caused by residual tool lines after mechanical processing.
