SKY WIN Technology Co., Ltd. is a joint-stock enterprise which combines research, manufacture and sales of WPC (wood-plastic composites) machines and profiles.
SKY WIN was one of the earliest factories which manufactured WPC machines and now is the only which specially produces WPC machines in China.
In the past 10 years, many experts have concentrated on WPC machines (granulators, extruders, and auxiliaries, etc. ), and now the company has accumulated a lot of experience on WPC equipment, moulds, technical formula, and products.
SKY WIN Honor:
1. ISO9001: 2000 QULITY MANAGEMENT SYSTEM CERTIFICATE has been passed; CE certificate for WPC extrusion lines has been approved; SKY WIN machines are certified as "International Advanced" by China government; SKY WIN participated as the drafter of China National Standard on WPC floorings.
2. SKY WIN has cooperated with many universities and research institutes. Now it is "Practice and Internship Facility" of Northeast Forestry University and Nanjing Forestry University.
3. WPC One-step Machines(patent) are technology advanced and exceptional in China or even in the world. SKY WIN WPC equipment has got 4 patents, and now is brought within in China Advanced Products Catalogue.
SKY WIN Market: Now SKY WIN machines for WPC are sold all over China, as well as many foreign countries and regions, such as Singapore, Italy, Mexico, Thailand, Malaysia, Indonesia, Taiwan, etc...
SKY WIN Service: Turn Key project, including WPC project feasibility analysis, workshop and electric facilities design, machine installation and test, staff training, formulation, mould adjust and test, after-sale service, etc...
