Changshanchuangheng Technology Electronics Co.ltd

We are Changshan Chuangheng Technology Electronic Co., Ltd in China. We supply semiconductor crystal bar （the P and N doped Bismuth Telluride crystals）for thermoelectric coolers (modules) with good quality and low price. Chuangheng Technology Electronic Co., Ltd was set up in January 2005. Occupying in Chang shang county in Zhejiang province, the light traffic and beautiful place, it is the first corporation which specialises in semiconductor crystal bar (the N and P doped Bismuth Telluride) for thermoelectric coolers/modules(Peltier coolers/TECs) in China. As we all know that the most important to increase temperature difference of TECs is to improve the quality of semiconductor crystal bar. Because TECs are made up of the N and P doped Bismuth Telluride (semiconductor crystal bar). You may be confused of low quality. The reasons may be as follow: 1 the parameter of crystal bar does not meet your requirements. 2 low density、much crack and many big air holes. To resolve the problem, Chuangheng set up a expert team with Russian experts taking the head, at the meantime, we establish cooperation relationship with advanced foreign manufactures of special automatic. As a result, the products have been improved not only in parameter, but also in density and air hole. We occupy the market by high quality and perfect service. Chuangheng has been a modern corporation with high technology and scientific management. We are looking forward to your enquires and cooperation.
