It is understood that the Ludington pumped storage power plant is located on the east coast of Lake Michigan, Michigan, USA. It was completed in the 1970s and the power station installed 6 sets of pumped storage units with a capacity of 312,000 kilowatts. In January 2011, the Toshiba Group of Toshiba Corporation of Japan won the bid for the upgrade and upgrade of 6 sets of 312,000-kilowatt pumped-storage units of the power station at a U.S.-based subsidiary, Toshiba International America.
Among them, the project's core unit - the overall runner, by the Toshiba Hydropower Company. The wheel weighs 260 tons, up to 4.5 meters, a diameter of 8.4 meters, is the world's largest pump turbine runner. According to the plan, the first unit runner was delivered in June 2013 and completed in 2019.
It is reported that Japan Toshiba Group in the pumped storage power generation equipment manufacturing in the high-capacity, high head, high-speed unit technology development in the forefront. As of March 2013, Toshiba Group has provided 75 pump turbines (total capacity of 18,302MW) and 65 electric motors (total capacity of 16,278MVA) to users all over the world.
Toshiba Hydroelectric Co., Ltd., as the sole overseas design and manufacturing base of hydroelectric equipment for Toshiba Group overseas, successfully developed the runner of the large-scale drainage storage unit of Ludington and fully demonstrated the company's ability to develop large-scale unit and equipment, User's approval.
Our company's expertise in close tolerance injection plastic molding, as well as our extensive knowledge of micromolding materials, enables us to advance the envelope of polymer science. Micromolding is one of the most difficult injection molding processes. In essence, the polymers used have "macromolecules". Handling these molecules at the tiny sizes required for micromolding is tricky because they often behave differently than they would normally do in larger applications. And, while all injection molding processes require strict tolerances, this is especially true in micromolding; Even the tiniest size change can make a part of this size unusable. Due to the unique and specialized nature of micromolding processes, we have to design new micromolding solutions for almost every project we undertake. Micromolding of very small parts naturally requires very small molds and tools. Because some of the mold pins, tool parts, etc., are only a few thousandths of an inch in diameter, even the metals we use in the mold become very fragile. Our molds and tools are manufactured using special micro-mold sources to ensure high quality and durability.
