Most of our activities are related to heat exchange.My own major in university is Material Science and Engineering at Central South University, mainly non-ferrous metal processing, and engaged for 10 years in flat-rolled aluminium clad material for automotive and industrial applications in Granges Shanghai(ever known as Sapa Shanghai).After that, we extend business along the non-ferrous metal and heat exchanging into metal brazing technology and heat exchanging related products. To better understand metal brazing, we study superalloy/high-temperature alloys, and non-ferrous metals in Additive Manufacturing(AM), Advanced Material as well as Advanced Manufacturing, especially by means of Wire Arc Additive Manufacturing(WAAM) raw material and Powder Metal in both AM and brazing.As applications of heat exchanging, we engage in products relating to heat exchanging in the past 2 decades:- All kinds of heat exchangers in automotive and industrial, like AC, new energy battery thermal management systems (BTMS), - Tube shell heat exchangers and Bundle Puller(Extractor) - Brazing material itself and its raw material in powder and wire for metal-to-metal, metal-to-ceramic brazing technologies- Application of all kinds of high-performance materials like Titanium, Nickle, Beryllium/Tellurium Copper, Al/Cu clad material, etc.- A further expansion is the cold chain products where the best heat exchanging process is utilized and more reaching to consuming markets like supermarkets, convenience stores, hotels, restaurants, etc.Thanks to the fast development of industries in China in the past 30 years, we have integrated a lot of resources pertaining to heat exchangers for our customers over the world. More important is that, with a new demand, we got to know how to find the right person/organization to the point.We are ready for cooperating with friends/customers working in these fields.
