Precision Casting, Perfected: Your End-to-End Lost-Wax Solution

Key Steps in Investment Casting

Wax Pattern Creation
Prototyping: Precisely carve or 3D print a wax model (e.g., jewelry, gears) to replicate the final part geometry.
Mass Replication: Use silicone molds to produce multiple wax patterns efficiently.
Quality Control: Inspect wax patterns for surface smoothness and eliminate bubbles/defects.
Wax Tree Assembly
Gating System: Attach individual wax patterns to a central wax sprue (runner) to form a tree-like structure.
Layout Optimization: Arrange patterns to ensure uniform metal flow and minimize turbulence during pouring.
Refractory Coating
Slurry Dipping:
Primary Layer: Dip the wax tree into a fine ceramic slurry (e.g., zirconia or silica-based) to capture surface details.
Secondary Layers: Apply coarser refractory coatings (e.g., alumina) to build shell strength.
Drying: Cure each layer in a controlled environment (humidity/temperature) to harden the ceramic shell.
Dewaxing & Firing
Steam Autoclave: Use high-pressure steam to melt and remove wax from the ceramic shell, leaving a cavity.
High-Temperature Sintering: Fire the shell at 800–1000°C to eliminate residual wax and strengthen the mold.
Metal Pouring
Alloy Melting: Melt the desired metal (e.g., stainless steel, titanium, or precious alloys) in a vacuum or inert atmosphere to prevent oxidation.
Casting Methods: Pour molten metal via gravity, centrifugal force, or vacuum-assisted techniques to fill intricate cavities.
Shell Removal & Post-Processing
Decoring: Break away the ceramic shell using mechanical vibration, water jetting, or chemical dissolution.
Cutting & Finishing: Separate individual castings from the gating system. Perform machining, polishing, or electroplating to meet specifications.
