Precision casting steps


Phase 1: Mold Engineering and Production


The mold is completed by Compass Hardware engineers and is the "negative film" of the final casting. Using casting molds, wax models can be sprayed with very precise dimensions and excellent contours. These wax models are glued together, glued to the so-called "tree wax", and then a casting funnel is installed. At the end of the process, the steel is poured into the hopper. Depending on the size of the series, the sand mold can be installed on a manual or automatic press.


Phase 2: Ceramics


After the wax models are glued together, the tree is provided with a fire-resistant ceramic shell. The shell is constructed by repeatedly submerging the tree (up to 7 or 9 times) in the slurry and sprinkling with ceramic sand. The ceramic layer is then hardened in a drying chamber and exposed to air.

After the layers are formed and dried, the wax is melted from the ceramic tree by using steam (120°C) in an autoclave. This is why it is called "lost wax casting". The molten wax can be regenerated and reused. The ceramic tree is then baked at a high temperature (1100°C), and the final strength is achieved through a sintering process. In this process, the remaining wax will be burned off.


Phase 3: Casting process


The required steel alloy is melted in a large furnace and reaches the casting temperature. At the same time, the ceramic tree is heated in the oven to prevent thermal shock during the casting process. Pour the steel in by anti-gravity. After casting the trees, they must be cooled in a cooling conveyor belt (with nitrogen). Then, use a fully automatic bionic hammer to break the tree, and remove the tree from the ceramic shell of the tree. This will remove most of the ceramics.


Stage 4: Finishing


The rest of the ceramic is removed in the finishing section by steel, sandblasting and/or water spraying. Then it involves sawing off the steel tree or vibrating the product. The remaining steel is classified by alloy and may melt again during the next casting mark. Finally, the casting is polished, and the product is machined, calibrated or heat treated if necessary. After passing the final inspection, the product is ready to be shipped to another satisfied Compass Hardware customer.
