▶ Vacuum Casting Materials:
    • Carbon Steel: Low Carbon Steel, Medium Carbon Steel and High Carbon Steel from AISI 1020 to AISI 1060. 
    • Cast Steel Alloys: ZG20SiMn, ZG30SiMn, ZG30CrMo, ZG35CrMo, ZG35SiMn, ZG35CrMnSi, ZG40Mn, ZG40Cr, ZG42Cr, ZG42CrMo...etc on request.
    • Stainless Steel: AISI 304, AISI 304L, AISI 316, AISI 316L and other stainless steel grade.
    • Brass & Copper.
    • Other Materials and Standards on request

▶ V Process Casting Capacities: 
    • Max Size: 1,000 mm × 800 mm × 500 mm
    • Weight Range: 0.5 kg - 100 kg
    • Annual Capacity: 2,000 tons
    • Tolerances: On Request. 

▶ Inspecting V-Process Casting Components: 
    • 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

▶ Vacuum Casting Procedures: 
    • The pattern is covered tightly by a thin sheet of plastic.
    • A flask is placed over the coated pattern and is filled with dry sand without bind.
    • The second flak is then placed on top of the sand, and a vacuum draws the sand so that the pattern can be tight and withdrawn. Both halves of the mold are made and assembled in this way.
    • During pouring, the mold remains under a vacuum but the casting cavity does not.
    • When the metal has solidified, the vacuum is turned off and the sand falls away, releasing the casting.
    • Vacuum molding produces casting with high-quality detail and dimensional accuracy.
    • It is especially well suited for large, relatively flat castings.

▶ Post-Casting Process
    • Deburring & Cleaning
    • Shot Blasting / Sand Peening
    • Heat Treatment: Normalization, Quench, Tempering, Carburization, Nitriding
    • Surface Treatment: Passivation, Andonizing, Electroplating, Hot Zinc Plating, Zinc Plating, Nickel Plating, Polishing, Electro-Polishing, Painting, GeoMet, Zintec. 
    • Machining: Turning, Milling, Lathing, Drilling, Honing, Grinding.

▶ Why You Choose RMC for V (Vacuum) Process Casting Components?
    • Easy recovery of the sand because the binders are not used
    • Sand does not require mechanical reconditioning.
    • Good air permeability because there is no water is mixed with sand, therefore less casting defects.
    • More suitable for large scale castings
    • Cost effective, especially for large castings.

▶ General Commerial Terms
    • Main workflow: Inquiry & Quotation → Confirming Details / Cost Reduction Proposals → Tooling Development → Trial Casting → Samples Approval → Trial Order → Mass Production → Continuous Order Proceeding
    • Leadtime: Estimatedly 15-25 days for tooling development and estimatedly 20 days for mass production.
    • Payment Terms: To be negotiated.
    • Payment methods: T/T, L/C, West Union, Paypal.
