Die casting is a Aluminium or Zinc metal casting process that is characterized by forcing nolten metal under high pressure into a die mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mould during the process. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.
The casting equipment and the metal dies represent large capital costs and this tends to limit the process to high-volume production. Manufacture of parts using die casting is relatively simple, involving only four main steps, which keeps the incremental cost per item low. It is especially suited for a large quantity of small- to medium-sized castings, which is why die casting produces more castings than any other casting process. Die castings are characterized by a very good surface finish (by casting standards) and dimensional consistency.

Beijing, October 22, 2014 – ABB, the world’s leading power and automation technology group, unveiled at the 15th International Power Equipment and Technology Exhibition today, demonstrating its comprehensive range of smart technologies and a full range of power generation, transmission and distribution. The overall power solution demonstrates ABB’s leadership in power technology.
Among the various technologies demonstrated, ABB's microgrid solutions have become a highlight. A microgrid is a small-scale power distribution system that is a collection of distributed power sources, energy storage devices, energy conversion devices, associated loads, and monitoring and protection devices. It can be operated in isolation or in conjunction with an external power grid. Become an important development direction of modern smart grid. The ABB microgrid solution demonstrated this time is made up of its micro grid system Microgrid Plus and Power Store.
ABB's Microgrid Plus microgrid system can make full use of clean energy such as photovoltaics, wind power and hydropower to help reduce carbon emissions and protect the environment. At the same time, the system can be installed on the power generation side according to the power consumption of the customer's end. The controller controls and automatically adjusts the power of the power generation system to achieve “load-based power generation†and 100% utilization of power generation, effectively avoiding the situation of insufficient power generation or excessive power generation and waste. The microgrid system has been applied in many projects around the world. For example, in the Azores in Portugal recently, the system has helped local wind power access and use, equivalent to saving 3.5 million liters of fuel per year.
The intermittent nature of renewable energy and dramatic changes in customer-side load are important challenges for microgrids. ABB's Power Store energy storage system stores electrical energy through flywheels and batteries, and releases the stored electrical energy quickly (within 5 milliseconds) when needed, which effectively protects the microgrid's stability and satisfies terminal power consumption. The system has been used for many years in the Zhangbei Scenery Storage and Transportation Project in China and has recently provided energy storage technology support for the Jinfeng Science and Technology Yizhuang Micronet pilot project.
At present, China is increasing support for distributed generation and will vigorously promote the integration of new energy distributed power sources such as photovoltaic and natural gas. The microgrids and energy storage systems provided by ABB provide innovative and effective solutions for grid-connected renewable energy, which can increase grid reliability and energy efficiency, maximise the use of renewable energy for power generation, and bring fossil fuels to the forefront. The environmental impact is minimized. ABB microgrid technology can improve the reliability of electricity and meet the needs of distributed generation in the Chinese market.
Zhang Jinquan, head of ABB’s China Power System Business Unit, said: "ABB is committed to providing reliable, intelligent and green power products and solutions for the Chinese market. We will continue to focus on the needs of the Chinese market and expand the product line for China's power supply. Building contribution."
The annual international power equipment and technology exhibition is the largest power exhibition in the domestic power industry, and has attracted much attention from domestic and foreign power industries. The 15th International Exhibition on Electric Power Equipment and Technology brought together more than 800 major suppliers from 16 countries and regions. The theme of this year's exhibition is "Smart, Energy Saving, New Opportunities", which is also the key word for China's power industry.
ABB is a global leader in power and automation technology. ABB is committed to helping customers in the power, industrial, transportation and infrastructure sectors to improve their performance while reducing their impact on the environment. ABB Group operates in more than 100 countries and employs 145,000 people. ABB has a full range of business activities including R&D, manufacturing, sales and engineering services in China. It employs 19,000 people and has 37 local companies and sales and service networks in 109 cities across the country.
