Sand castings or permanent mold castings? Since we offer both casting processes here at Meteor Foundry, we often get posed this question. What is the difference between these two casting processes and which one is better suited for your application? Let’s clear up the casting confusion with a cursory overview.Sand Castings: A one-time sand mold is produced, which may contain one or more impression...

Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal. The most common process uses gravity to fill the mold, however gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush casting, produces hollow castings. Common casting metals are aluminium, magnesium, and copper alloys. Other ...

Corrosion Resistant - Stainless Steel Alloys Castings are classified as “corrosion resistant” if they are used in aqueous environments and vapours below 650°C. To perform well in a corrosive environment the carbon content should be low and usually below 0.20% and sometimes below 0.03%. Based on microstructure Corrosion resistant cast alloys are grouped as Martensitic, Austenitic, or Duplex.High St...

What is the benefits and advantages of Cast Irons in Engineering Applications？1.Available in a wide range of mechanical/physical properties, i.e. tensile strength from 20 KSI to over 200 KSI, hardness from 120 to about 300 Brinell in standard grades and up to about 600 Brinell in special abrasion resistant grades2.Good strength to weight ratio3.Typically lower cost than competing materials and r...

What is lost wax casting?Lost wax casting, also called precision or investment casting is a casting technique, in which an exact duplicate of the original wax sample is being created. This can be achieved by coating successive ceramic layers on the wax model until a strong shell envelops. After melting out the wax, molten metal will be poured into the ceramic mold, creating a perfect duplicate of ...

What are the factors affecting tolerance, dimensions and surface finish of precision casting?Maintaining close dimensional tolerance in an investment casting is affected by many factors. Most of these factors can be controlled by the foundry, although minor “lot to lot” variations will occur. The tolerance bands provided for investment castings are determined by these uncontrollable factors.

1.Pattern creation - The wax patterns are typically injection molded into a metal die and are formed as one piece. Cores may be used to form any internal features on the pattern. Several of these patterns are attached to a central wax gating system (sprue, runners, and risers), to form a tree-like assembly. The gating system forms the channels through which the molten metal will flow to the mold c...

What kind of surface treatment we can do?Polishing, painting, powder coating, plating, chroming, UV finish, water-based finish and so on.

What is the material of your product?All kinds of ferrous metal, stainless steel, carbon steel, alloy steel, nodular cast iron, gray cast iron and etc.
