Liaoyang Petrochemical Co., Ltd. has been working on the research of cross-linked polyethylene since 2007. In 2008, it undertook the cross-linked polyethylene resin development project. After more than one year of research and development, small-scale test, pilot test and applied research, it finally achieved industrial production. And passed the national standard test. The test results show that the hydrostatic resistance and thermal stability of pipe products produced from this raw material have reached the level of South Korea's LG Chemicals, Samsung Chemicals and other equivalent products, and has significant advantages in terms of molecular weight distribution and particle size, which can replace imported similar products.
It is understood that crosslinked polyethylene special resin is the main raw material for floor heating plastic pipe production. At present, domestic demand for plastic pipe production enterprises for domestic heating reaches 60,000 tons/year.
Deep drawing is one of the most popular metal forming process of forming blank sheets of metal into a desired shape. Equipped with deep draw presses range in tonnage capacity from 5 to 350 tons, MSG` deep drawn presses are capable of deep drawing various metal types with material thicknesses from 0.2mm - 6mm, part diameters from 2mm - 900mm, and lengths up to 1000mm.
Deep drawing process provides better strength properties, seamless structure, consistency on the finished parts, and it is especially beneficial when producing high volumes. The process is also recommended for product geometries that are unachievable through other manufacturing methods. Deep drawn products are of all shapes and sizes, such as assembly housings, kettles, cans, cookware, and kitchen sinks. MSG`s engineers prepare metal blanks in advance of the deep drawing process to ensure that the finished parts are free from tears and imperfections.
