Small forgings are of wide range applications but high technical requirements. With professional technical experience, L ongcheng has obtained many forging national patents, and can offer customers kinds of small forging development plans.

With forging experience over two decades, Longcheng focuses on the development of forgings less than 5kg, and is especially experienced at small alternator engine forging gears, pulleys, automotive gear forgings, and small forgings for construction machines, petroleum machines and coal mine machines.

High-speed railway parts are of safety first and high technical requirement. With the continuously development of high-speed railway industry, traditional casting parts are more and more difficult to meet the technical demands.

With advanced forging techniques, rich experience and consummate management system, Longcheng develops the high-speed railway forgings, successfully realizing precision forgings’ national development to replace the import and fill the gaps in domestic market.
