General investing casting processes containsfive steps,wax injection,shell moulding,casting,surface treatment, andinspection. Below are the detail step descriptions of the investment casting processes. Step 1,Wax injection Melting wax first, theninjecting wax into the patterns to get the wax models.
Jul 07, 2020· Investment castings involve an exact and strict casting process through theuse of the lost-wax process to create components in the metal cast alloys. This process is known to be very accurate, creating components with accurate dimensions and smooth surface finishes. With this process, the machining and finishing processes are reduced.

Though relatively straightforward, the investment casting processinvolves a number of detailed steps. To begin,manufacturers must create a master die or wax pattern. Though not always made of wax, this feature gives the process its alternate names of wax casting and lost wax casting. This form is an exact replica of the part to be produced.

Lost Wax Investment Casting Process. In lost wax investment casting, asacrificial detailed wax pattern of the desired finished part is created and mounted onto a wax "tree", whichincludes the metal delivery system (gates and risers). The tree is alternately dipped into a ceramic slurry and sprinkled with stucco material, and is allowed to dry.

Casting is the key step in the whole investment casting process. After dewax, we will first melt the steel ingots into liquid status, and pour the liquid metal into the sprue, then cool it under room temperature for a while. 6.Knock out Break the ceramic shell, and cut the individual investment castings from the sprue.
