Metal casting is a technology to manufacture products by pouring liquid materials into molds to create products shaped in the form of metal materials.

Advantages and disadvantages of metal casting

- Advantages:

Casting methods can make products from different materials: ferrous metals (cast iron, steel, metal ..: aluminum, copper, cast non-metallic materials: casting statues from plaster, cement bamboo shoots)

Castings can range from a few grams to several tons such as hammer bodies, platforms, etc.

Castings with complex shapes and structures such as machine tool bodies, engine covers, etc., which other methods are difficult to manufacture or cannot be manufactured

It is possible to cast various layers of metal in a casting

Costs of making castings are cheap because of low investment capital, flexible production properties and relatively high productivity. Ability to mechanize and automate.

Castings are also used in the manufacture of artistic and decorative products: foot of electric pole, church bell, monument casting.

- Defect:

The accuracy of size and shadow shapes is not high

Metal cost for pouring, bean filling, steam bean system

Metal cost due to the greater thickness of castings compared to forging or welding.

It is easy to cause defects such as deficiency, pitting, tearing, astronomical, sand burning

Heavy working conditions. When casting in sand molds often have low productivity.

Current metal casting technologies

- Casting in metal molds:

Casting in metal molds is the term for a method of manufacturing castings by pouring liquid metal into metal molds. The cast is solid under the effect of gravity without any other effect. This is a very popular method today because it has the following characteristics:

Molds are used many times;

The cleanliness and accuracy are significantly improved. This will reduce the volume of mechanical processing;

Improve the mechanical strength of castings, especially the durability of the surface adjacent to the metal mold.

Increase annual output by reducing the size of beans and cast waste.

Improve labor productivity.

Save workshop area because there is no need to make mold mix and mold making process.

Reduce product costs.

Easy to mechanize and automate, good sanitary conditions.

- Metal casting technology by dry mold:

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

- Metal die casting technology:

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

- Metal casting technology by sand mold:

Casting sand molds can be said to be a traditional casting method. With materials mainly sand, the additive can create a unique name for each individual method. The following are sand casting methods

- Furan metal casting technology:

This is the technology line that Japanese companies favor because sand will be mixed with Furan resin and acid, the mold will harden very well, the product has smooth surface but difficult problem is environmental pollution. work because furan plastic smell is very toxic

Application of metal casting

Metal casting is quite widely used in practice

- Producing consumer goods: casserole, pan, spoon ..

- Manufacturing machine parts: such as steam hammer body, deep lathe, reducer box, cylinder, gear

  • Quang Trung Mechanical Enterprise - metal casting specialist

    Quang Trung Mechanical Enterprise was established and developed since 1992. In the first stage, the unit went into metallurgy, researched and produced heat-resistant, abrasion-resistant, acid-resistant grades. impact resistant ... The growth of the Enterprise started from the material field, we have provided a wide range of industrial products for cement plants throughout the country, replacing imported goods, the prices are only 50 - 60% of imported goods

    In parallel with the detailed production and detailed assemblies, in 2000 Quang Trung Mechanical Enterprise focused on researching the field of lifting equipment, we have standardized and localized the details of the need. Crane and successfully fabricated crane equipment with loading capacity: from 5 tons to 50 tons ... for chemical plants, cement ...

    In 2004, we successfully designed 80-ton base crane for Vietnam's shipbuilding industry; Next is the successful production of lifting equipment with large loads from 100 .... 1200 tons to serve industries in the country.

    With modern facilities and equipment, investment is synchronous and in-depth; together with a team of engineers, skilled technical workers, Quang Trung Mechanical Enterprise commits to satisfy all partners with the motto:

    "Prestige - Quality - Competitive price - dedicated service - Sustainable trust".
