Why 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.
