Lost Wax Casting Process
Ancient technique perfected with modern precision
Pattern Making
Precision metal dies created from CAD designs for consistent wax pattern reproduction.
Wax Injection
Molten wax injected into dies under controlled pressure and temperature.
Tree Assembly
Individual wax patterns assembled onto a central wax sprue to form a 'tree'.
Shell Building
Wax tree dipped in ceramic slurry and coated with refractory sand, repeated multiple times.
Dewaxing
Wax melted out in autoclave, leaving a precise ceramic mold cavity.
Shell Firing
Ceramic shell fired at high temperature to burn out residual wax and strengthen the mold.
Metal Pouring
Molten alloy poured into preheated ceramic shell for optimal filling and solidification.
Finishing
Shell knockout, gate removal, heat treatment, machining, and final inspection.
Why Lost Wax Casting?
Complex Geometries
Intricate internal passages, undercuts, and complex shapes impossible with other methods.
Tight Tolerances
Dimensional accuracy of ±0.1mm achievable, reducing machining requirements.
Excellent Surface
Superior surface finish (Ra 3.2-6.3 µm) as-cast, minimal post-processing needed.
Design Freedom
Near-net-shape parts with thin walls, logos, and fine details in a single casting.
Any Alloy
Compatible with virtually any castable alloy including ferrous and non-ferrous metals.
Cost Effective
Reduced machining, minimal waste, and part consolidation lower overall costs.
