Company Introduction:
Dongguan Ming Rui Ceramic Technology Co., LTD., a professional manufacturer of machined ceramic parts, has 10 senior engineers and lots of technicians. We produce strengthened structure zirconia ceramic bar, ceramic tube, ceramic shaft, ceramic plate, ceramic sleeve, ceramic valve, ceramic plunger and ceramic arm. The products are applicable to instruments, medical instruments, clocks and electronic products, mills, energy and power, machine and metals, autocar and military and some other high-end areas.
In cooperation with Tsinghua University, we've achieved great successes in particular requirements. With our professional knowledge and business experience in machined ceramic parts, low-budget and high-performance new ceramic products are made of high–quality raw materials. The value of our ceramic products is greatly increased due to the composite technology and precise processing.
Our high efficiency machined ceramic parts, perfect service and good reputation roots in our professional machined ceramic technology, continuous innovation, great sincerity and our pursuit for sustainable development. We have a unique technnology called “mirror polishing” that has improved the brightness, color, smoothness of our ceramic parts.
