Neihuang Lida Olympic metal processing www.nhldga.com, is engaged in mining and processing custom trays, card cable, the board first processing professional processing factories. Lida Olympic Since its inception, has been committed to the establishment of custom processing, technology first for the purpose of the modern enterprise. We always adhere to the "quality of survival, integrity and development" business philosophy, with excellent quality products and quality service well received by customers. In an isotropic mine as tray, when there is a boundary surface, in addition to some expansion wave (P-wave) and shear waves (distorted wave, also known as shear), also produce Rayleigh elastic SAW. Rayleigh in 1887 conducted a study, he proved this CSR wave propagation velocity is less than the speed of the object inside the wave, but also with the strength of its waves deep into the mine tray and quickly reduced. As waves enter the sample tray increases mining depth, the amplitude fluctuation increases initially, at a depth of 0.076 times the wavelength at the maximum value, and then monotonically decreasing; at a depth of a wavelength, where the amplitude of the wave will be reduced to the surface of the small value of 0.19 times. The company organized structure, processing technology force, equipped with a number of large-scale hydraulic equipment, the annual production capacity of 6 million units. Perennial accept mine trays, card cable, plate head custom processing business, has become the industry benchmark in northern regions of the processing enterprises. We will continue to uphold the "integrity beyond" the purpose, and industry colleagues to create a cause of a better tomorrow. Welcome to our customers and industry colleagues around the country to our base to visit, study guide. Custom tray, the force of the IOC is your preferred manufacturers.
