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.
