The company of Shanghai He Mao, it was established at 2001, it has introduced some first level brand of printing products into China market. In 20 years of cultivate, the share in China high-end market for the world's first level brand printing material has been achieved about 70%. Due to the experiences which the company has been collected during 20 years, also the background of the owner (who was studying steel technology) we launched the independent innovation brand AD doctor blades as began in 2010, the main difference was that: 

1. Due to the development of China printing industry, the suppliers need to timely updating their matched materials to their customers.For instance, when printing Some special anti-counterfeiting printing ink, our AD doctor blades of coated not only used in Shanghai tobacco package printing co., LTD., especially for a package project which named Greater China (name of the cigarette) with blue anti-counterfeit printing ink，the test result showed speciality of the Doctor blade, but also adopted by the special anti-counterfeiting printing Science technology co., LTD in China.

2. We have our own metallographic analysis laboratory, It is not a simple copy doctor blades technology but it is on the basis of technological innovation to the development, our unique 1 ° bevel angle edge which solves the blades broken crack untimely problems at Gravure Cylinder of two-terminal, by using this technology, there is no need for manually to make 1 ° bevel angle on Gravure Cylinder two-terminal to solve the problem. The technology has been approval by the vast number of gravure and flexo customer (including Shanghai tobacco package printing co., LTD. Of the nine color gravure press also are using AD high carbon steel blade).

3. Our coated doctor blades technology obtained under the guidance of the international association of coating, therefor to reach independent innovation breakthrough, also the technology obtained two patents in China.

Our company has the specialized equipment which allowed us together with the users to adapt to the needs of the new printing process. We will regularly visit user or telephone contact, communicate with each other, learn from each other and to promote the international level of synchronization of new printing materials in printing industry and achieve a win-win situation.
