TYPE OF STAINLESS STEEL CASTING

Type of stainless steel casting methods in Vietnam

There are many stainless casting methods currently being applied on the market. The general principle of stainless steel casting methods is to create a mold cavity to pour molten metal into and then cool to create products. Each method has its own applications:

Stainless steel casting by Sand casting method 

The method that the casting houses currently apply is the method of casting glass-water-sand with carbon dioxide (CO2). Glass water, also known as sodium silicate solution, is mixed with sand and then made into a mold cavity. The mold cavity after being shaped is sprayed with CO2 gas to solidify the mold. It is due to the chemical reaction between sodium silicate and CO2 gas and water (reaction between alkali and acid). The advantage of sand mold is that it can cast products of large sizes but the surface quality is not good and requires a large amount of processing residue.

Stainless steel casting by shell mold casting method 

This is a sand-casting method with high automation capabilities. Sand is covered with a layer of plastic. The metal mold is heated and then filled with plastic sand. Molten plastic sand sticks together to form a thin mold cavity. Combining the two halves of the mold cavity and the core (if necessary) will create a complete mold cavity ready for liquid metal pouring.

Stainless steel casting by lost wax casting method 

The casting is wax made from aluminum molds or rubber molds. The wax sample is then attached to the pouring system forming the sample beam. This sample beam is dipped in ceramic sauce (ceramic slurry) and then sprinkled on it so that the sand sticks to it. Repeat this process to create the mold coat. The sample beam is then dried and then melted with wax to form a cavity ready for liquid metal pouring.

Stainless steel casting by lost foam casting method 

The molded sample is made from foam. The molded sample is formed into a beam similar to a melt casting, but instead of embedding it to form a thin shell mold, the sample beam is placed in a mold box and compacted with sand-like sand casting. When pouring liquid metal into the foam sample beam. This sample beam will burn and the liquid metal will fill and the burned sample beam will form the casting. The fire casting method is more accurate than sand casting because it does not have to remove the sample from the mold cavity.

INTRODUCTION OF STAINLESS CASTING BY HESEM

We are proactive in consulting, designing, and manufacturing stainless steel molds. We have reliable sand casting and lost wax casting partners. They have accompanied HESEM to carry out many successful projects. We unite to form a strong collective and understand each other. The sample product after the molding process is checked by our engineer against the requirements to modify the mold if necessary. After that, we process and send it outside for finishing stages: anodize, dip paint, plating… Products are then returned to the HESEM warehouse for final inspection by engineers before packing and delivery. for customers.
