Vacuum assisted casting technology, casting density ≥98% (X-ray testing ASTM E155)

2. Special post-treatment process

Electrolytic polishing (EP) : Surface roughness Ra≤0.8μm, improve corrosion resistance

Solid solution treatment (1050℃ water quenching) : optimize the crystal phase structure and eliminate the casting stress

3. Digital finishing

Five-axis CNC machining center, key dimensional tolerance ±0.02mm

Intelligent inspection: Coordinate measurement (±0.01mm) + industrial CT scan (internal defect detection)

4. Surface strengthening technology

Shot peening: increase fatigue life by more than 30%

PVD coating (optional) : enhanced wear resistance (friction coefficient ≤0.15)

Product introduction

Mechanical stainless steel castings are made of 304/316 stainless steel (ASTM A743 standard) by precision investment casting process, with excellent corrosion resistance (96-hour salt spray test) and mechanical strength (tensile strength ≥515MPa), widely used in pump valve housing, hydraulic parts and food machinery and other industrial equipment. The product adopts silica sol composite shell making (7-9 layers) and vacuum pouring technology to achieve 1.5mm thin-wall complex structure forming (accuracy ±0.15mm/100mm), and is enhanced by electrolytic polishing (Ra≤0.8μm) and solution treatment (water quenching at 1050℃), combined with five-axis CNC finishing (±0.02mm tolerance) and industrial CT detection. High reliability solutions for harsh industrial environments.
