Custom Stainless Steel Castings By Lost Wax Investment Casting
Ming Xiao Mfg outsourcing stainless steel castings for our customers,and sometimes our machined parts need casting rough parts,so we also outsourcing rough stainless steel castings then precision machining to final finished parts in our own factory.
Stainless steel casting usual technology is Lost wax casting(or call it investment casting),investment precision casting process refers to the use of wax to make a model, wrap multilayer clay, binder and other refractory materials on its surface, heat it to melt and flow out the wax, thereby obtaining an empty shell formed by the refractory material, and then melt the metal and pour it out.
After the metal is cooled, the refractory material is broken into the empty shell to obtain metal parts. This metal processing process is called investment casting, also known as investment casting or lost wax casting.
It’s can use different material to be the bond medium, such as sodium silicate sand casting & Silica sol casting.
The difference of Two technologies is:
1)sodium silicate sand casting suit to low precision(allow big tolerance, generally +/-0.3mm at least), surface rough,but cost is low, processes simple, production period shorter.
2)Silica sol casting can produce high precision parts, can control the tolerance in +/-0.15mm, surface is good, but processes are complicated,production period is long, cost is very high.
The technics & capabilities: Lost wax investment casting (Silica sol casting,sodium silicate sand casting
Materials: SS304 & SS316L.
Finish treating: Sand ripple, sandblasting, mirror polishing, color separation, and passivation.
Precision casting products are used in all industrial sectors, especially electronics, petroleum, chemical, energy, transportation, light industry, textiles, pharmaceuticals, medical equipment,architectural hardware, bathroom,furniture hardwares, pumps and valves.
If you like our service to custom stainless steel investment castings for your project, please don’t hesitate to contact with us.
Lead time for custom samples of stainless steel castings is 30days.
Lead time for mass production:generally a order is 45-60days, if machining process is too complicated or quantity is very high,the lead time will longer.
We can provide COC (material certificate), Test Report,Compositions analysis report ROHS / SGS.
