Beijing Sanwei Sporting Goods Co., Ltd.

Beijing Sanwei Sporting Goods Co., Ltd. is a professional manufacturer of table tennis balls, table tennis rackets, table tennis equipment.

We own a proprietary intellectual property of table tennis rackets with super-light carbon mat added in. The patent number is ZL-02246034.9. Super-light soft carbon of felt structure is a kind of thin carbon fiber mat wet processed, which is a new technology. Its fibers are multi-directionally inter-woven, with a smooth surface and strong adsorb ability. The carbon mat is 30g/square meter on average and the compressed thickness is 0.1 mm. Each layer of fiber mat is approximately 1g, so suppose a pure wooden blade is 80g. Then it will be 90g when 9 layers of fiber mats are added. Let us take the 10-layer wood and 9-layer carbon blade for example. It consists of 10 layers of thin wood and 9 layers of high-tech carbon mat. The wood has lost almost all its internal stress after having been planed many times and the 9 layers of carbon mats are added evenly between the 10 blade layers to achieve reinforcing effect like that of steel bars on a building. Carbon fiber has far more deformation and rebounding capability and much higher energy absorbing and releasing efficiency than natural wood fibers.

The carbon mats contain no ethoxyline resin, but they are blended with the spirit of carbon material, and other scientific fabricating techniques. Nanometer-level adhesives are also used. Soft carbon of felt structure, high quality wood and nanometer-level adhesives work together to achieve the standards of the first-class professional table tennis blades. It is a perfect experience on combination of speed and control and is fully competent to exceed any other table tennis blade both at home and abroad.
