About China Die Casting

Modeling is based on making core casting process requirements in determining a good method of modeling, ready to shape the material basis. Casting the accuracy of all of the production process and the economic effects will depend mainly on this procedure. In many modern casting workshop, modeling-made batteries have achieved a mechanized or automated. Sand commonly used form core-making equipment is high, medium and low pressure molding machine and threw sand machine, without me radio pressure molding machine, radio-core, cold and hot-box machines.

Since the casting mold in cooling pouring out after a gate, riser and metal spikes Phi slit, sand casting of the casting also adhesion of the sand, it must be clean-up process. Such devices are the work of the Blasting machine, gate riser cutting machines. Sand-casting sand clean-up is a poor working conditions processes, in the choice of modeling methods, should be taken into account for as much as possible with sand to create convenient conditions for clean-up. Casting a result of some special requirements, but also by casting post-processing, such as heat treatment, plastic surgery, anti-rust treatment, such as rough.

Casting is more economic methods of rough shape, the shape of more complex components demonstrated its economy. aluminum die casting Such as car engine block and cylinder head, ship propellers and exquisite works of art, and so on. Cutting some of the difficult parts, such as the combustion turbine parts do not have to nickel-based alloys casting method can not be forming.

In addition, the die casting of parts of the size and weight to a wide range of metal types of almost unlimited; parts in a general mechanical properties, it is also a wear and corrosion-resistant, shock-absorbing properties, and so is the other metal forming methods such as forging , Rolling, welding, salt, and so can not. Therefore, in casting machine manufacturing methods used in the production of rough parts, and the number is still on the tonnage is the largest.

Casting often use a variety of metal materials, coke, wood, plastic, gas and liquid fuels, such as modeling materials. Have the necessary equipment used in various metal smelting furnace, a Mixer with the various Mixer, a shape-made batteries used in various molding machine, machine-made batteries, cleaning up the castings used for loading sand, Shot Blasting Machine And so on. Casting is also available for special machinery and equipment, and many transportation and material handling equipment.

Casting and other technology have different characteristics, mainly wide adaptability, needed materials and equipment, pollution of the environment. Casting will have dust and harmful gases and noise pollution to the environment, compared to other machinery manufacturing processes to become more serious, need to take measures to control.

Casting product development requirements of the trend is casting a better overall performance, higher accuracy and less headroom and clean the surface. In addition, the requirements of energy-saving society and restore the natural environment of the call also getting higher and higher. To meet these requirements, the new cast alloy will be developed, the new smelting technology and new equipment will be corresponding.

Casting the mechanized production continuously improve the degree of automation in the same time, to be more flexible production development, to expand the volume and variety of different production adaptability. Conserve energy and raw materials of new technologies will be giving priority to the development, have little or no pollution of the new equipment, new technology will be the first attention. Quality control technology in all stages of testing and nondestructive testing, stress determination, there will be a new development
