Manufacturing Process & Quality Commitment
As a long-term strategic supplier to Fortune 500 companies, we consistently deliver unmatched quality and reliability.
Manufacturability Analysis
Evaluate the part design against the characteristics of investment casting (e.g., minimum wall thickness, core formation limitations, hot spot locations). If the design may lead to casting defects (such as shrinkage or hot tearing), modification suggestions should be proposed at this stage.
3D Simulation of Gating Systems
Through computer simulation, the gating system design is validated, enabling high-precision prediction of the mold filling flow, solidification process, temperature field evolution, and defect formation of the molten metal within the cavity. The core goal is to eliminate or reduce internal defects such as shrinkage cavities, porosity, misruns, and gas entrapment, thereby improving the process yield.
Pattern Production
Create a metal die based on part drawings; inject molten wax under pressure to form a high-precision wax pattern, followed by trimming and deburring to ensure surface finish and dimensional accuracy.
Wax Pattern Injection
Molten wax or plastic is injected into the die and cooled to form a pattern identical to the final part.
Wax Pattern Repair
Manually remove flash and imperfections; conduct dimensional and visual inspection on wax patterns.
Wax Tree Assembly
Attach individual wax patterns to a central wax sprue to form a “wax tree,” enabling simultaneous casting of multiple parts and uniform metal flow.
Shell Building
Dip the wax tree into a refractory slurry (e.g., silica sol), followed by stuccoing with fine zircon or quartz sand; repeat 5–7 times to build a thick, high-strength ceramic shell.
Dewaxing
Heat the dried shell in a steam autoclave or furnace to melt and drain the wax, leaving a hollow cavity matching the original pattern.
Shell Firing
The dewaxed ceramic shell is fired in a kiln at very high temperatures (often exceeding 1000°C). This process burns off any residual wax, sinters the ceramic to achieve its final strength and permeability, and preheats the shell to an optimal temperature for casting.
Chemical Analysis
After the brass alloy is melted in the furnace, a sample of the molten metal is taken, cooled, and then analyzed using a spectrometer for chemical composition. The inspector issues a complete composition test report, which is compared against the customer’s specified composition requirements. If the comparison meets the requirements, the process proceeds to the next step—casting. If the comparison
does not meet the requirements, casting is stopped, and the melting process is repeated.
Pouring
Choose alloy (bronze, brass, silver, gold, aluminum, some steels). Each has distinct melting points and behavior. Melt in a crucible furnace appropriate for the alloy. Flux and skimming: remove dross and oxidized surface layer.
AI 3D Scanner Dimensional Inspection
Uses an AI-driven 3D scanner to take a complete 360-degree scan of the finished casting. Scanning: A high-precision 3D scanner quickly captures complete point cloud data of the casting's surface. Comparison: The actual 3D model obtained from the scan is automatically compared against the original design drawings (CAD model). Analysis: A color-mapped deviation report is generated, visually displaying the dimensional errors at every point, allowing for precise verification of whether critical tolerances are met.
