Investment casting is a casting technique. It involves injecting liquid wax into a metal mold to create a wax pattern that is identical to the desired casting. Subsequently, multiple layers of refractory ceramic materials, such as clay, are applied to the exterior of the wax pattern. Upon heating, the wax melts and flows out, resulting in a hardened ceramic shell. This ceramic shell is then fired to remove any residual wax and to strengthen the shell. Molten metal is poured into the ceramic mold, and after the metal cools and solidifies, the ceramic shell is broken away to reveal the finished metal casting.
Lost foam casting is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax.
This casting process is advantageous for very complex castings that would regularly require cores. It is also dimensionally accurate, maintains an excellent surface finish, requires no draft, and has no parting lines so no flash is formed.
SHENGRONG provides lost foam castings range from 1 kg to 1,000 kg, Maximum size of the flask is 1100 x 1100 x 1000 and produces casting volumes from prototype to 20,000 tons per year.
No-brake resin sand molding is a sand molding process where synthetic liquid resin is mixed with the sand, and the mixture hardens and cools at room temperature. The casting is formed by pouring liquid metal into the resulting mold cavity after the sand mixture is fully cured and the mold halves are assembled together. This process takes place in a normal atmosphere without adding heat to the mold prior to the pour.
