Why Choose COOWIN

HIGH LEVEL OF QUALITY

Every kind of product has an extraordinary soul, and every kind of process contains the spirit of craftsmanship.

The story of COOWIN began in a small factory 19 years ago. As one of the earliest wood-plastic factories in northern China, the founder, Mr. Leo, invested a lot of money and energy in introducing formulas and technologies from the US. Then, this small factory has grown step by step to become one of the most well-known wood-plastic enterprises in China.

At present, COOWIN’s self-developed formula has obtained national patents, and each raw material has strict physical and chemical indicators; the production equipment specially designed for COOWIN has been put into use.
