Metal casting is a technology to manufacture products by pouring metal materials (stainless steel, cast iron, alloy steel, aluminum alloy, copper alloy, alloy …) in a molten state into the mold cavity to create the product has a molded shape, after the metal solidifies in the mold, the molded product will be taken out.

Metal casting is a technology with very high flexibility and can produce mechanical parts with complex shapes, regardless of the mechanical properties of metal hardness, only depending on the melting temperature of the metaltype.

It can be said that any metal that can be melted can be cast.

Today, metal casting is used to create thousands of different parts, widely used in all industrial fields such as machine building, transportation, petroleum, marine, cement

Advantages and disadvantages of metal casting

  • The casting method can make products from different materials: ferrous metal (cast iron, steel, .. grinding metal: aluminum, copper, casting non-metallic materials: casting statues from plaster, cement, etc.) bamboo shoots)
  • Castings can range from a few grams to several tons, such as hammer bodies, machine platforms, etc.
  • Castings have complex shapes and structures such as machine tool bodies, engine housings, etc. that are difficult to process or impossible to fabricate by other methods.
  • Multiple layers of metal can be cast in one casting
  • The manufacturing cost of castings is cheap because of low investment capital, flexible production properties, and relatively high productivity. Capable of mechanization and automation.
  • Casting is also used in the manufacture of artistic and decorative products: electric pole legs, church bells, monument casting.

Disadvantages of metal casting

  • The accuracy of shape, size and silhouette is not high
  • Consumes metal for pouring system, hot beans, steam beans
  • Metal cost due to greater wall thickness of casting than forging or welding.
  • It is easy to cause defects such as deficiency, porosity, suffocation, miscalculation, sand burning
  • Harsh working conditions. When casting in sand molds, the productivity is often not high.

Self-adhesive resin cements may be used for all packages with zirconia and alumina middle ceramics, solid steel, PFM, and for cementation of solid put up and cores and prefabricated steel and fiber posts.

These cements are dual-treatment and permit a clean clean-up at a gel phase. Many of the cements on this category are to be had in dual-tube automixing configurations or in a few instances in preloaded drugs which can be jumbled together with a high-velocity triturator.

Fresh sand molding technology

Fresh sand molds were first used in sand casting technology. The material for making the mold is water clay. Fresh sand mold has the characteristics of easy to use, will give the surface of the casting a glossy if the sand grain is fine.

However, in the mold making process, the sample must be shaken to escape, so the molded product will have a large processing redundancy.

Dry sand molding technology

In dry mold technology, if the fresh mold is dried in an oven for about 5 hours before pouring, it is also called a dry mold. Here, I would like to introduce to you the technology of carbon dioxide-cured glass-water sand mold.

Glass water, also known as sodium silicate solution, is mixed with sand and then pounded into the mold. After the mold has finished pounding, spray carbon dioxide to solidify the mold.

It is due to the chemical reaction between sodium silicate and carbon dioxide and water (reaction between alkali and acid) .

Glass water sand mold technology is easy to make, easy to use, the product has less processing redundancy, and the mold is solid has been widely applied in most foundries nationwide.

Only downside is the problem of sand regeneration that must be taken into account.

Fire mold casting technology

This is a newer technology than the traditional method. To mold a product, we need to make that product with polyester, then put it in the mold and pour dry sand in, combined with vacuum suction, the mold will be solid.

When metal is poured into the mold, the Polyester sample burns and the liquid metal fills the mold. In addition, with the technology of making dry cores and sintering made on automatic machines for high productivity and efficiency.

Plastic sand molding technology

This is a new technology with sand that has been treated by the factory and covered with a plastic layer.

When manufacturing, mix sand with formaldehyde acid, it will be cold-cured by a plastic sand mold, or heated sand mold will be hot-cured by a plastic sand mold.

Furan casting technology

This is a technology line favored by Japanese companies because the sand will be mixed with Furan resin and acid, the mold will harden very well, the product has a smooth surface, but the problem is environmental pollution work because the smell of Furan resin is very toxic.
