This is the first step of stainless steel investment casting. Based on the product needed, we design it or get design drawings from clients.
After the mold is ready, inject wax into the mold cavity. Then take out the wax model from the mold after cooling. Inspect and Repair some appearance defects of wax models, such as slot, wax injection nozzle, flow pattern, etc. tree.
After inspection of wax models, weld them to the casting system one by one to form an assembly. It looks like a tree, So this step is also called Tree Assembly
The shell building is a whole silica sol process. It will repeat and dry and harden. Firstly, dip the assembly into a good colloidal silica coating. Then sprinkle with fire-resistant sand. Until to dry and harden. To form dense refractory coating surface outside the surface of wax models. Then repeat the step 5-6 times. Finally to get a certain strength and refractoriness of silica sol shell.
Put the shelling into the high-temperature oven. The wax inside the shell is melted by heating. Then drain out. Finally, we get a cavity that can be poured into the mold. This process is called Dewaxing.
The stainless steel ingots melt into liquid status under high temperatures. Then pour the liquid into the shell and cool at room temperature.
Cut the stainless steel casting blanks. Remove the sprue gate by grinding machine
Smooth the surface by various surface finishes, such as shot blasting, sandblasting, electropolishing, mirror polishing, etc.
If the product needs further processing, we need machining again.
After finishing production, Do an inspection.
The inspection process is also an indispensable process before delivery. The inspection of stainless steel castings includes dimensional inspection, defects inspection, and material inspection. Only qualified products can be shipped to customers.
