Zhou Ming Technology: The first quarter net profit pre-drop 77.11% -94.28%

Zhou Ming Technology announced the first quarter of 2012 performance forecast on the evening of March 30th. The company expects net profit attributable to shareholders of listed companies from January to March 2012 to be between 500,000 yuan and 2 million yuan, a decrease of 77.11%-94.28% over the same period of the previous year.

The announcement said that the company's operating performance declined in the first quarter of 2012, mainly due to the impact of the European debt crisis in 2011, and the intensification of domestic LED application product competition, the company's export sales and domestic sales have decreased compared to the same period last year; Shenzhen in 2012 The minimum wage for full-time employed laborers in the city has been raised to 1,500 yuan/month from February 1. The company's labor costs have risen during the reporting period, which has caused the company's product gross margins to have a certain impact; in order to improve the company's competitiveness, the company The increase in R&D, sales, and key post management personnel has resulted in a certain increase in management expenses sales expenses.

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.
