Investment Casting (Lost-Wax Casting)
Investment casting, also known as lost-wax casting, is an ancient yet advanced metal forming process centered around precision wax patterns. The process involves: creating a meltable wax pattern via CNC machining or 3D printing → coating the pattern with multiple layers of silica sol and zircon sand to form a ceramic shell → steam dewaxing to create a cavity → pouring molten alloys (such as stainless steel, titanium alloys, or superalloys) → breaking the shell to retrieve the finished component.
Key Features:
- Exceptional mold precision: The ceramic shell achieves ultra-high accuracy with cavity replication errors ≤0.05mm, enabling the formation of highly intricate hollow structures, curved surfaces, and fine textures (minimum aperture of 0.3mm).
Core Advantages:
- Ultra-Precision Tolerances: Achieves dimensional tolerances of ±0.1mm and mirror-like surface finishes (Ra 1.6-6.3μm), reducing machining allowances by up to 90%.
- Wide Material Compatibility: Supports a broad range of materials, from carbon steel and aluminum alloys to nickel-based superalloys, with casting temperatures exceeding 1600℃.
- Flexible Production Volumes: Economically viable for batches ranging from single units to thousands, making it ideal for customized, high-end components.
- Seamless Design Integrity: The monolithic ceramic shell eliminates parting lines, preventing misalignment and enhancing structural integrity.
With its core capabilities of “precision without limits and universal material adaptability,” investment casting serves as an indispensable solution for high-end, complex metal components. It is widely applied in industries such as aerospace, medical devices, jewelry, energy, and defense. Especially in the context of new material innovations and miniaturization trends, investment casting continues to lead precision manufacturing into the future.

Precision Casting Capability at a Glance
Precision casting, investment casting and lost wax casting all describe the same route: a wax pattern, a ceramic shell, and a near-net part that needs far less machining than one cut from solid. We run the silica sol version of the process, which holds finer surfaces and tighter cavities than cheaper water-glass shells — the difference shows up on valve seats, impeller passages and any surface you would rather not machine twice.
Process Capability
- Silica sol ceramic shell, cavity replication error within 0.05 mm
- Minimum aperture down to 0.3 mm for fine internal detail
- Thin walls and undercuts without extra machining allowance
- Steam dewaxing and controlled shell firing
- Full process walkthrough, step by step
