The EV Group started to expand the production workshop at the Austrian headquarters last month. The new building is adjacent to the existing production facilities. The total area is more than double the company's existing plant floor area and is scheduled to be completed by the end of this year.
It is reported that while the EV Group is expanding, it will plan a new area specially set up for visitors. This area is a large glass dome with two sides. Customers and visitors can see the production area and a complicated access management through the glass. system.
In addition, the accompanying test room will facilitate the development and customization of the customer's personality, which is especially important for LED manufacturers with proprietary processes and differential automation levels.
While expanding, EV Group has further invested in expanding the capacity of its processing centers, developing new manufacturing technologies, and plans to further update existing production facilities. EV will recruit approximately 100 employees in the areas of manufacturing and technical support in the near future.
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.
