Pengenalan kepada Tuangan Ketepatan Sol Silika
Silica sol precision casting is a process that uses silica sol as a mold material to solidify in a mold to form a precision casting by injecting molten metal or alloy.
Silica sol has the characteristics of high temperature stability, low thermal expansion coefficient, high-precision forming ability and excellent surface quality, and is suitable for preparing castings with complex shapes and high-precision requirements. Compared with traditional casting methods, silica sol investment casting can achieve higher dimensional accuracy, better surface finish and more complex internal structure.
The main steps of silica sol precision casting include mold preparation, mold baking, grouting, drying and sintering. First, according to the shape and size requirements of the casting, a silica sol mold is prepared, usually by coating the silica sol on the surface of the mold to form a film. Then, the mold is baked to solidify the sol to form a silicon mold. Next, molten metal or alloy is injected into the mold, filling the entire cavity. Then, through processes such as drying and sintering, the metal or alloy is solidified and separated from the silica sol, and finally the precision casting is obtained.
Silica sol precision castings are widely used in aerospace, automotive, electronics, medical equipment and other fields, and have the advantages of light weight, complex structure, high precision and superior performance.
