STWS Material TECH Group was established in 1998, it is mainly engaged in three major businesses of packaging material, High precision aluminum foil and functional film. In February 2010, the company was listed on the Shenzhen Stock Exchange.
High-precision Aluminum Foil Business
Subsidiary JSZJ Aluminum Foil Technology Company, established in 2004, is a high-tech enterprise focusing on high-precision aluminum foil, and is a large-scale professional manufacturer of double zero aluminum foil in Asia.
The production capacity of high-precision aluminum foil reaches 70,000 tons; the marketing and service network covers the Americas, Europe, Asia and other global regions.
High-precision aluminum foil is a composite material that is laminated with foil paper and foil film after cold-rolling and rolling. The company has mastered the production technology of ultra-thin wide-width capacitor aluminum foil (thickness 0.005MM, width greater than 1M), to achieve uniform aluminum foil thickness, no joints, and fewer pinholes. All indicators have reached the standards of the United States General Electric and ABB; independent research and development 8079D alloy aluminum foil greatly reduces the air permeability and oxygen permeability of the product, and can be widely used in the field of liquid-grade aluminum foil for food and medicine, effectively improving the shelf life of food and medicine.
The company's aluminum foil rolling mill comes from the world-class rolling mill manufacturer: Achenbach Buschhütten GmbH & Co. KG's rough, medium and finishing rolling mills, and is equipped with VC rolls, plate shape gauges, thickness gauges and other high precision equipment. New rolling equipment, optimized rolling process and energy saving and environmental protection technology, coupled with a group of trained operating experts, make the aluminum foil surface quality control, shape control, thickness control and other indicators can meet multiple purposes The requirements of aluminum foil products make low energy consumption, stable quality and high yield of medium-based aluminum foil products.
Optical and Electrical Films Section
The Optoelectronic Film Branch has developed into a high-tech enterprise integrating R & D, production, and sales of ITO conductive films and special films, and has independently developed core patented technologies. The company's conductive film has various performance indicators such as transmittance, haze, chromaticity index, and surface resistance value, which have been widely praised by users. It has become an upstream supplier for Lenovo, Coolpad and other brand manufacturers. .
The main products of Photoelectric Film Section
Functional thin films such as capacitive ITO conductive film,
Highly transparent ITO conductive film,
Resistive ITO conductive film
Product Quality:
The ITO conductive film produced by the company has been tested by the SGS testing agency, and its test results meet the limit requirements of the EU RoHS Directive 2002/95 / EC Reordering Directive 2011/65 / EU Appendix.
Our core competitiveness:
● High quality R2R sputtering system
● High quality production environment (class 1000, parts are class 500 ↓)
● Excellent R2R sputtering experience and Optical films simulation technology
● Complete production width ranges and Large capacity
● Customer orientation development & service
Window Film Section
The company target at the high-end and mid-end window film market. Window film is a thin film / laminate retrofit coating upgrade, which can be installed to the interior of glass surfaces to address problems inherent to glazing, including heat retention, thermal insulation, energy saving, UV filtration, decoration, safety and privacy. The use of window film can be roughly divided into two categories based on intended end use, automotive and architectural.
In the field of functional film, the company has gained rich experience of vacuum coating, sputtering, lamination and coating technology, enabling our excellent product performance. We have an experimental technician team, some of which are from overseas, and have built up advanced management system.
The market demand of automotive window film boosts with the increasing amount of automobiles. For architectural use, 95% of the domestic architectures are high energy consuming, which is 2 to 3 times of the western countries. The demand for architectural window film is also boosting as a result of the increasing awareness of environmental protection. Wanshun's window film meets the green development trend of environmental protection and energy saving, which will lead to a broad market prospect.
