Metal casting is the technology of making products by pouring the material in liquid form onto the mold to create a molded product in which the material is metal.


Metal casting is the technology of making products by pouring the material in liquid form onto the mold to create a molded product in which the material is metal.

Advantages and disadvantages of metal casting

- Advantages Casting Metal:

Casting method can produce products from different materials: ferrous metal (cast iron, steel, .. metal eye: aluminum, bronze, non-metallic casting: cast the statue from gypsum, xi bamboo shoots)

Castings can range from several grams to several tons such as hammers, machine platforms.

Molds have complex shapes and shapes such as machine tool body, engine cover, etc., which other methods are difficult to process or can not be fabricated.

It is possible to cast different layers of metal in a cast

The cost of making cheap castings is low due to the low investment capital and the high production capacity. Ability to mechanize and automate.

Castings are also used in the manufacture of artistic products, decorative: feet of the pillars, church bells, monument molding.

- Disadvantages of metal casting

Accuracy of shape and size is not high

Metal for pouring, peanut, bean

The metal is made of thicker castings than forged or welded.

Easy to cause defects such as deficiencies, porosity, suck, sacred, sand fire

Hard working conditions. Molded in sand molds are often not very productive.

Current metal molding technologies

- Casting in metal molds:

Casting in a metal mold is the term for a method of producing castings by pouring liquid metal into a metal mold. Castings freeze under the effect of gravity without any other impact. This is a very common method now because it has the following characteristics:

Mold used many times;
Cleanliness and accuracy are greatly enhanced. This will reduce the amount of mechanical machining;
Enhance the mechanical strength of the castings, especially the durability in the surface layer adjacent to the metal mold.
Increase annual yields by reducing the size of the shrimps and castings.
Improve labor productivity.
It saves the area of ​​the workshop as it does not require the manufacture of molds and molds.
Reduce product cost.
Ease of mechanization and automation, good hygiene conditions.
- Casting technology:

In dry molding technology, if the fresh mold is dried in the oven about 5 hours before pouring, it is also called a dry mold.

- Casting metal molding technology:

We need to make that product in polyesteron, then put it in the mold and pour the dry sand, combined with the vacuum, the mold will harden. When poured into the mold, Polyesteron will burn and the liquid metal will fill the mold

- Sand molding technology:

Sand molding can be said to be a traditional casting method. With materials mainly sand, the accompanying additives can create a unique name for each specific method. Here are the sand molding methods

- Furan metal molding technology:

This is a technology line that Japanese companies prefer because the sand is mixed with Furan resin and acid, the mold will cure very well, the product is glossy surface, but the difficulty is the pollution of the environment. Worked for the smell of Furan resin very poisonous

Application of metal casting

Metal casting is widely applied in practice to

- Produce consumer goods: casserole, pan, spoon

- Manufacture of machine parts: steam hammer body, lathe machine, gear box, cylinder, gear

- Manufacturing fine art goods.

Kim Thinh - Kim Thinh Corp. - specialist in metal casting: is one of 10 companies specialized in metal casting industry. We believe that will meet all needs of customers, whether the most difficult customers at home and abroad

Kim Thinh Corp was established and developed since 1992. In the first stage, the company has gone into the field of metallurgy, researching and producing all kinds of heat-resistant, abrasion-resistant, acid-resistant and impact resistant steel grades. ... The maturity of the enterprise started with the field of materials, we have provided a range of industrial products for the cement factories in the country, replacing imported goods, cost only 50 - 60% of imported goods

In parallel with the production of detail and detail assemblies, in 2000 Kim Thinh Corp focused on the field of lifting equipment. We standardized and localized the crane parts. Successfully manufactured crane equipment with load: from 5 tons to 50 tons ... serving for Chemical Plant, Cement ...

In 2004, we successfully designed and manufactured the 80 ton crane for the Vietnam Shipbuilding industry. Next is the successful production of lifting equipment with a large load from 100 .... 1200 tons for the ash industry
