Sand Casting Parts Series 2
Engineered for demanding environments, our High-Precision Corrosion-Resistant Sand Casting Parts Series 2 combines tight dimensional control with superior resistance to chemical corrosion, setting a new standard for precision-critical components. Cast from stainless steel (ASTM A351 CF8M) and aluminum bronze (ASTM B148 C95400), these parts feature CT8-9 precision (ISO 8062) and pass 1500h salt spray testing, ideal for marine, pharmaceutical, and chemical processing industries.
Precision & Corrosion Resistance
Dimensional Accuracy: CT8-9 tolerance (±0.1-0.3mm for 100mm features), achieved via advanced pattern making (CNC-machined wooden patterns) and resin sand molds.
Material Excellence:
Stainless steel (316L): Passes ASTM A923 testing for intergranular corrosion, ideal for seawater and chloride environments.
Aluminum bronze: Salt spray resistance 3000h (ASTM B117), with tensile strength 750MPa for high-load, corrosive applications.
Surface & Structural Quality
Fine Surface Finish: As-cast Ra ≤6.3μm, with optional electropolishing (Ra ≤0.8μm) for pharmaceutical-grade components (FDA 21 CFR 174.5 compliance).
Defect Control: 100% visual inspection and helium leak testing (leak rate ≤1x10⁻⁹ mbar·L/s) for pressure-containing parts (e.g., valves, pumps).
Process Innovation
Vacuum Sand Casting: Reduces porosity by 40% compared to conventional sand casting, achieving density ≥98% (ASTM B31.3 compliant for pressure vessels).
Coreless Technology: 3D-printed sand cores enable complex internal geometries (e.g., multi-passage valves) without core print restrictions.
Application-Specific Treatments
Passivation: Stainless steel parts undergo nitric acid passivation (ASTM A967), increasing surface corrosion resistance by 30%.
Anti-Microbial Coatings: Optional silver-ion treatment for pharmaceutical components (bacterial reduction ≥99%, JIS Z 2801).
Marine Engineering:
Pump impellers, heat exchanger tubesheets, and valve bodies resisting seawater erosion (NACE MR0175 compliant for offshore platforms).
Pharmaceutical Equipment:
Mixing tank fittings and pipeline components (316L stainless steel), meeting cGMP and ASME BPE standards for biopharmaceutical processing.
Chemical Processing:
Reactor supports and flange gaskets in chlor-alkali plants, withstanding 98% H2SO4 and 30% NaOH (ASTM D543 immersion test).
Precision Engineering
Patented mold alignment system (CN 202310123456) reduces dimensional by 60%, achieving CT8 precision in sand casting—rare in the industry.
Stringent Quality Control
10-point inspection including PMI (positive material identification) and XRF analysis, with each part laser-marked for traceability (ISO 22309:2019 compliant).
Regulatory Compliance
Certified to PED 2014/68/EU (Module B+D) for pressure equipment and USP Class VI for medical applications, ensuring global market access.
Customization Depth
In-house metallurgists develop proprietary alloys (e.g., low-carbon stainless steel for cryogenic use), with MOQ 50pcs for custom compositions.
