PROCESS
1.WAX INJECTION:Wax design of the desired castings are produced by injection molding.These designs are called patterns.
2.ASSEMBLY:The patterns are attached to a central wax stick,called a sprue to form a casting cluster or assembly.
3.SHELL BUILDING:The shell is built by immersing the assembly in a liquid ceramic slurry and then into a bed of extremely fine sand.Up to eight layers may be applied in this manner.
4. DEMAX:Once the ceramic is dry,the wax is melted out,creating a negative impression of the assembly within the shell.
5.CONVENTIONAL CASTING:In the conventional process,the shell is filled with molten metal by gravity pouring.As the metal cools, the parts and gates,sprue and pouring cup become one solid casting.
6.KNOCKOUT:When the metal has cooled and solidified,the ceramic shell is broken off by vibration or knock-out machine.
7. CUT OFF: The parts are cut away from the central sprue using a high speed friction saw.
8.CLEANING AND GRINDING: When the formed casting parts are finished, they will be cleaned by hand work totally.After that, all the parts will be put in to the grinding machine for spot blasting. After these operations, the metal castings becomes identical to the original wax patterns.
9.HEATTREATMENT: Once the parts are finished by cleaning, they will be put in to heat treatment machine , in order to get a good harness and anti-wear,as well as good impact performance.
10.PAINTING: Sprat painting method is used to paint the parts with different colors. Then they will be given special time for dry, so that they can be kept as shining and smooth.
11.PACKAGE: Man-made wooden carton is used for package,which is no need for fumigation.
12.SHIPPMENT: When all these work is done, finished products is ready to ship to every corner of the world.
