Zhejiang Wang Year Knitting Co., Ltd. was established in 1993, the address is located in Yiwu Beiyuan Industrial Park Road No. 115 Chun Han. The total production workshop of the company is about 16,000 square meters, with more than 100 sets of the most advanced seamless knitting machines in Italy (including all models from 12 inches to 17 inches) and hundreds of industrial sewing sewing machines in Japan. Talent allocation with the company: with more than 30 professional and technical personnel, more than 400 ordinary employees, technical and management staff of more than 95% of the college, the technical force is very strong. So far, the company's total assets have exceeded 200 million yuan.

The company mainly produces seamless knitting products, including general underwear series, body lingerie series, sports series, fashion series, the products are exported to major cities in China and the United States, Canada, Australia, South America and many other countries and regions, And many well-known international brands have had good cooperation, including GUESS, SEARS, TARGET, KHOLE'S, ZARA, FOREVER21 and so on. The company adopts the high standard of modern enterprise management, fully implements the ISO9000 series standard certification and establishes the quality certification system, so as to comprehensively improve the management quality, product quality and service quality of the enterprise. It has been awarded the quality management system, occupational health and safety management system, Standardized good behavior and environmental management system and other aspects of the certificate.

The company has been rated as innovation and excellence of advanced enterprises, green advanced enterprises, outstanding integrity of private enterprises, industrial growth enterprises in Yiwu and credit AAA level, Shou contract re-credit units, Jinhua famous brand, Yiwu brand-name products. Now "Year of the Man" is a new spirit of climbing the highest peak of seamless underwear industry. We warmly welcome distributors all over the world to cooperate sincerely with us on the basis of mutual benefit.

Piezoelectric Material

Yuhai piezo materials include : hard piezo material, soft piezo

material and lead free piezo material 

Soft piezo

material exhibits: larger piezoelectric constants, higher permittivity, larger

dielectric constants, higher dielectric losses, larger electromechanical

coupling factors, low mechanical quality factors, a lower coercive field, poor

linearity, and is easier to depolarize. The ideal application of soft piezo materials is sensing needs. Yuhai soft

pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51.  

Hard piezo

material exhibits: smaller piezoelectric constants, lower permittivity, smaller

dielectric constants, lower dielectric losses, smaller electromechanical

coupling factors, high mechanical quality factors, a higher coercive field,

better linearity, and is harder to depolarize. The ideal application of hard piezo materials is high power transducer needs. Yuhai  hard pizeo materials are PZT-4, PZT-8, PCrN-4 and PBaS-4.  

Yuhai company developped lead free piezo material BaTiO3 and apply for the Chinese Patent in 2011, to meet the needs of environmental protection in today's society.
