OEM Custom Aluminium Vacuum Casting Parts

OEM Custom Aluminium Alloy Vacuum Casting Parts with engineering services from ideas to markets.

The vacuum castings could be used at a wide range of industries. It can be used for single-piece small batch production as well as mass production, especially large and medium-sized castings and thin-walled castings are more suitable for vacuum casting. Therefore, the vacuum castings are mainly used for agricultural machineries, hydraulic systems, rail freight cars, cranes and shipbuilding industries.

▶ 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• The second flak is then placed on top of the sand, and a vacuum draws the sand so that the pattern can be tight and withdrawn.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.
