Key Challenges in Sanitary Component Casting
Casting sanitary components from high-temperature alloys presents specific challenges:
Corrosion and Chemical Resistance: Ensuring stable microstructures and uniform alloy composition to resist aggressive media exposure.
Dimensional Accuracy: Meeting tight dimensional tolerances (±0.1 mm) crucial for sanitary fittings and sealing.
Surface Quality: Maintaining smooth, defect-free finishes (Ra 0.8–3.2 µm) for optimal hygiene and reduced microbial growth.
High-Temperature Stability: Achieving consistent performance and integrity at elevated temperatures (up to 1200°C).
Detailed Casting Process for High-Temperature Sanitary Components
Wax Pattern Preparation
Highly accurate wax patterns produced within ±0.05 mm dimensional precision, enabling consistent and repeatable component geometries.
Ceramic Shell Formation
Robust ceramic molds created via multiple slurry-dipping layers, forming shells typically 8–12 mm thick, suitable for molten alloy temperatures above 1300°C.
Vacuum Melting and Precision Casting
Vacuum induction melting performed at ultra-low pressures (<0.1 Pa) to ensure exceptional alloy purity and minimal oxidation.
Controlled casting ensures defect-free components with uniform grain structures and excellent corrosion-resistant properties.
Finishing and Inspection
Ceramic shells removed carefully via chemical dissolution and mechanical methods.
Precision CNC machining refines final dimensions (±0.1 mm) and surface finishes (Ra 0.8–3.2 µm).
Rigorous inspection, including NDT, guarantees compliance with stringent hygienic and industry standards.
