The foundry practice has with the other craft different characteristic, is mainly the compatibility broad, needs the material and the equipment are many, pollution of the environment. The foundry practice can produce the dust, the noxious gas and the noise to the environment pollution, compares other machine manufacture craft to come to be more serious, needs to take the measure to carry on the control.

The casting product development's tendency is requests the casting to have a better overall performance, higher precision, less remainders and brighter and cleaner surface. In addition, the energy conservation request and the society to restore the natural environment the call to be also getting higher and higher. In order to adapt these requests, the new casting alloy will obtain the development, will smelt the new craft and the new equipment will appear correspondingly.

Foundry practice's mechanization automaticity while is enhancing unceasingly, more will develop to the flexible production aspect, expands to the different batch and the multi-variety production compatibility.

Will save the energy and the raw material new technology will obtain gives priority to development, little will produce or does not produce the pollution new craft new equipment first to receive takes seriously. The quality control technology in each working procedure's examination and the lossless crack detection, the stress determination aspect, will have the recent development.
