Die casting (English: die casting) is a kind of metal casting process, its characteristic is to use the mold cavity of melting metal under pressure. Moulds are usually with higher strength alloy processing, this some similar molding process. Most die castings are not iron, such as zinc, copper, aluminum, magnesium, lead, tin and lead tin alloy and their alloys. According to different types of die casting, need to use the cold chamber die casting machine and hot chamber die casting machine.
Casting equipment and die of expensive, so the die casting technology in general will only be used for batch manufacturing of products. Make the parts of the die casting is relatively easy, this generally need only four main steps, single cost increment is very low. Die casting is especially suitable for manufacturing a large number of small and medium sized castings, so die casting is the most widely used in all kinds of casting process. Compared with other casting technology, the surface of the die casting is more smooth, consistent with a higher size.
On the basis of the traditional die casting technology was born several kinds of advanced technology, including reducing the casting defect elimination pores without hole die casting technology. Mainly used for processing zinc, can reduce waste to increase yield of direct injection technology. General dynamics and invented by semi-solid die casting die casting technology and fine speed and so on the new die casting technology.
Die casting machine of the significance of the reform of energy saving is not only to reduce power consumption, more advanced control system can help small businesses to save labor costs, improve product quality and process, so as to improve enterprise competitiveness. In energy-saving "green wind" prevailed in the era background, the enterprise should be "zero tolerance" for high energy consumption.
China has many such enterprises, the annual revenue is less than 3 million yuan, production workers in about 20 people, because these miniature enterprise profit space is not large and often is considered not suitable for energy saving transformation. That was not the case, not long ago, cheng dhi Qingdao machinery co., LTD., through a series of energy-saving reform measures, more than ten thousand yuan, the annual savings artificial cost integrated save more than ten thousand yuan a year. Prove to be small miniature enterprise applies to energy conservation and emissions reduction, and even enterprise transformation of the necessary measures.
At the same time, in environmental protection "the strongest method", still there are a lot of similar enterprises faced with pressure energy saving.
Servo energy-saving system into the optimal choice
Servo energy-saving technology in recent years, with the mature application of servo motor and its drive system is widely used and a sharp fall in prices. Servo system generally includes servo motor, servo drive and high-performance pump parts. Different from the traditional motor, servo motor has quick response speed, high precision, strong stability, etc, with servo drives, can accurately implement motor stop soon turn fast, save a lot of energy loss.
According to the original, said an official with the energy saving technology of energy-saving reconstruct a complete servo can realize the energy saving of 45% to 85%, and the production efficiency increased by 5%. Not only that, after the energy conservation transformation, energy conservation enterprise can also obtain appropriate subsidies from the country, compared with other optimization measures, servo energy-saving reform has become many enterprises the best choice.
