As a leading China foundry specializing in stainless steel components, we provide premium casting services utilizing the advanced Lost Wax Casting Process. Also known as investment casting, this method delivers exceptional dimensional accuracy, superior surface finishes, and complex geometries for critical applications across multiple industries. Our technical expertise ensures reliable performance in corrosive, high-temperature, and high-stress environments.
Premium Stainless Steel Materials
We work with a comprehensive range of stainless steel alloys to meet diverse operational requirements. Our standard offerings include:
304/304L Stainless Steel: Excellent all-purpose corrosion resistance and formability
316/316L Stainless Steel: Enhanced corrosion resistance with molybdenum addition
17-4PH Stainless Steel: Precipitation-hardening grade offering high strength and hardness
CF8M & CF8C: Casting-specific grades with optimized properties for foundry processing
Each alloy undergoes rigorous material certification to ensure compliance with ASTM, DIN, and other international standards, guaranteeing consistent chemical composition and mechanical properties.
Advanced Lost Wax Casting Technology
Our investment casting process combines traditional craftsmanship with modern technology:
Pattern Creation: Precision injection of wax patterns using temperature-controlled dies
Assembly & Coating: Mounting patterns onto trees and applying ceramic slurry coatings
Dewaxing & Firing: High-pressure autoclave dewaxing and high-temperature mold firing
Casting & Finishing: Controlled atmosphere pouring followed by shell removal and cut-off
This process achieves exceptional dimensional tolerances (ISO CT4-6), surface finishes to 3.2 μm Ra, and minimal draft angles, significantly reducing secondary machining requirements and material waste.
Superior Performance Characteristics
Components produced through our lost wax casting service deliver:
Corrosion Resistance: Excellent performance in acidic, alkaline, and saline environments
High-Temperature Strength: Maintains structural integrity at elevated temperatures
Pressure Tightness: Dense, homogeneous microstructure prevents leakage
Design Flexibility: Complex internal passages and thin walls (down to 3mm)
Cost Efficiency: Near-net-shape production reduces material waste and machining costs
Comprehensive Industry Applications
Our stainless steel castings serve demanding applications across multiple sectors:
Valves & Pumps: Impellers, valve bodies, and pump casings for chemical processing
Food & Pharmaceutical: Sanitary fittings, processing equipment, and mixer components
Marine & Offshore: Hardware, propeller components, and deck fittings
Architectural: Decorative elements, hardware, and structural components
Automotive: Turbocharger housings, engine components, and exhaust parts
With full-spectrum capabilities from design assistance to final inspection, we provide complete manufacturing solutions backed by comprehensive quality assurance including X-ray inspection, dye penetrant testing, and dimensional verification. Our China-based operation combines competitive pricing with international quality standards, delivering value without compromise for global clients seeking reliable stainless steel casting services.
