Yesterday, the reporter learned from Shunde Inspection and Quarantine Bureau that in the future, Shunde will implement three-level hierarchical supervision on lighting export enterprises, and new products that are included in the third category of enterprises must be exported after obtaining relevant reports.
The Shunde Inspection and Quarantine Bureau has conducted a comprehensive survey on exporting lamps and lanterns enterprises, and found that the state of the enterprises in this industry is mixed. Some export products produced by some enterprises have potential safety hazards.
To this end, the bureau will implement three levels of stratification supervision for all lighting companies in the jurisdiction. The relevant person in charge of the bureau said that enterprises with high credibility evaluation, ISO9000 system certification, and stable quality of export products will be included in the management of Class I or Class II enterprises, and others will be included in the third category of enterprises for supervision.
Export companies that are included in Category 1 and 2 will receive more preferential policies. In the annual review of the type test confirmation, the operation of the system, the quality of the exported products and the export integrity record may be postponed for one to two years, while the third type of enterprise may not be postponed. In the daily supervision, the new products of the first-class enterprises and the second-class enterprises can be temporarily checked and exported after passing the inspection of the industrial products laboratory, and the new products of the third-class enterprises must be allowed to be exported after obtaining the type test qualification report.

Piezoelectric Ceramic are a ferroelectric compound. This means, that the electro-mechanical conversion process for producing a motion is related a kind of self-enhancement process based on an internal reorganization of the material's structure. This self-enhancement process results in the higher piezoelectrical efficiency of PZT when compared to natural materials like quartz.
Piezoelectric ceramic are generally manufactured from PZT (Pb - lead, Zr - zirconium, Ti - titanium). The PZT- formulation can be varied with a variety of dopants allowing for a broad spectrum of material properties optimized for different application profiles.
Yuhai Company is able to manufacture piezoelectric ceramic elements in a wide range of shapes and sizes. piezoelectric discs, piezo rings, piezo plates, and piezo tubes (cylinders) is the main shapes Yuhai Company most frequently manufactures, we also have a great deal of experience manufacturing hemispheres, trapezoids and other customized shapes.
If the listed shapes and sizes was not the elements you are looking for, please contact us for more information. We can work with you to create the correct shape and size for you.Piezoelectric Elements,Piezo Ceramic Disc,Piezoelectric Ceramic Discs,Pzt Element
