investment casting for stainless steel

Advantages of Investment casting

Compared to traditional casting methods, Investment casting has several significant advantages, mainly including the following aspects:

Better surface quality of castings: Investment casting uses fine silica sol particles to form dense and smooth molds, making the surface 

of castings smoother and smoother, greatly reducing the need for subsequent processing and improving product quality.

High dimensional accuracy: Silica sol molds have better dimensional stability and lower shrinkage, which can maintain good shape 

stability under high temperature conditions, thereby achieving higher dimensional accuracy in castings. This makes the silica sol 

process particularly suitable for manufacturing complex parts with high precision and high requirements.

Stronger environmental friendliness: The binders, clays, and chemical additives used in traditional casting processes 

are prone to decomposition at high temperatures, releasing harmful gases or dust to the environment. And silica sol 

belongs to inorganic materials, which generate less waste during the casting process and significantly reduce environmental pollution.

Process flexibility: Silica sol casting can meet the production needs of complex parts and is suitable for casting parts with 

complex shapes and fine structures. Due to its ability to achieve high precision, silica sol molds are suitable for precision 

casting of various metal materials, such as stainless steel, carbon steel, alloy steel, etc.

can produce some complex structure parts and think parts,though the casting cost is higher than precision casting,

the process from modeling, 

develop the casting mold and tooling,wax injection,shell making,baking the shell,lost wax,and pouring,remove the shell,

in order to holding the tolerance,we usually need to adjust the pouring gating and riser,

like the picture, some features that get from the investment casting, we can use them directly, no need machining,

also we can provide the precision cnc machining for some iimportant feature,
