• Other Alloy Steel as per ASTM, SAE, AISI, GOST, DIN, EN, ISO, and GB.
▶ What We Can Achieve by Investment Casting:
• Max Size of Investment Casting: 1,000 mm × 800 mm × 500 mm
• Weight Range: 0.5 kg - 100 kg
• Annual Capacity: 2,000 tons
• Binder Materials for Shell Building: Silica Sol, Water Glass and their mixtures.
• Tolerances: CT5 ~CT7 or on request.
▶ Steps of Lost Wax Casting:
• Patterns & Tooling Design → Metal Die Making → Wax Patterns Injection → Slurry Assembly → Shell Building → De-Waxing → Chemical Composition Analysis → Melting & Pouring → Cleaning, Grinding & Shot Blasting → Post Processing or Packing for Shipment
▶ What Measures We Take to Inspect the Investment Castings:
• Spectrographic and manual quantitative analysis
• Metallographic analysis
• Brinell, Rockwell and Vickers hardness inspection
• Mechanical property analysis
• Low and normal temperature impact testing
• Cleanliness inspection
• UT, MT and RT inspection
▶ What We Can Do after Investment Casting:
• Deburring & Cleaning
• Shot Blasting / Sand Peening
• Heat Treatment: Normalization, Quench, Tempering, Carburization, Nitriding
• Surface Treatment: Passivation, Anodizing, Electroplating, Hot Zinc Plating, Zinc Plating, Nickel Plating, Polishing, Electro-Polishing, Painting, GeoMet, Zintec.
• CNC Machining: Turning, Milling, Lathing, Drilling, Honing, Grinding.
▶ Advantages of Investment Casting Process:
• Excellent and smooth surface finish
• Tight dimensional tolerances.
• Complex and intricate shapes with design flexibility
• Capability to cast thin walls therefore a lighter casting component
• Wide selection of cast metals and alloys (ferrous and non-ferrous)
• Draft is not required in the molds design.
• Reduce the need for secondary machining.
• Low material waste.
