Chengdu Duolin Electric Co., Ltd

In 1994，the first High Frequency Induction Heating Equipment was developed by Chengdu Duolin Electric’ founder, Mr. Zengxiaolin. Now Duolin has about 200 employees, 12, 000 square meters modernized factory, the annual yield is 5, 000 sets.
As a professional induction heating supplier, Duolin designs and produces induction generators in 70 models, which power output ranging from 2kw to 1500kw at frequencies ranging from 0.5 kHz to 1.2 MHz. With 13 national patents, Duolin induction system for industrial induction heating can be applied to any heating process, e. g. forging & forming, brazing, heat treatment, shrinking, bending or hot extrusion.
In 2007, Duolin starts to develop oversea market. Our induction machines sold more than 30 countries such as Canada, USA, Brazil, Argentina, UK, Germany, Poland, Russia, Australian, Singapore, Indonesia, Saudi Arabia, Iran, Kuwait, South Africa mor etc. The number is still increasing….
