Präzisionsfertigung von integrierten Türgriffen aus Edelstahl
- Material Selection
The process begins with high-grade 304 or 316L stainless steel, chosen for its superior corrosion resistance, mechanical strength, and polished finish capabilities. The chromium-nickel composition ensures longevity in diverse environmental conditions. - Investment Casting Process
Wax pattern creation using CNC-machined molds
Ceramic shell building through multiple dipping cycles
High-temperature dewaxing (850-1000°C)
Controlled atmosphere melting and pouring at 1500-1600°C
Precision cooling in vibration-isolated chambers
- Post-Casting Treatment
Shot blasting for surface refinement
CNC machining for dimensional accuracy (±0.1mm tolerance)
Electrolytic polishing for mirror finishes
Passivation treatment to enhance corrosion resistance
- Quality Assurance
X-ray inspection for internal defects
Salt spray testing (500+ hours)
Load testing (minimum 500N cyclic force)
Surface roughness measurement (Ra ≤ 0.4μm)
- Technical Advantages
Seamless one-piece construction eliminates weak points
5-10 times stronger than conventional assembled handles
Maintains structural integrity from -40°C to 300°C
100% recyclable material with minimal environmental impact
Applications:
High-security facilities
Marine environments
Luxury residential projects
Commercial buildings requiring vandal-resistant hardware
