The heat tube is the main mobile phone accessories in general, in the production process of copper cooling tube, will use a central rod , in recent years, the application of zirconia ceramic center rod more and more widely, is gradually replacing the stainless steel center rod. the main reason lies in the following points:
1. zirconia ceramics have good heat insulation performance. In the process of production, the heating rate is very slow, so the quality of the product is better.
2. zirconia ceramics have better performance than stainless steel at high temperature and low temperature condition, and the service life is usually several times as high as that of the stainless steel center rod.
Dongguan Mingrui Ceramic Technology Co.,LTD is a professional manufacturer of machined ceramic parts, has 10 senior engineers and lots of technicians. We produce strengthened structure zirconia ceramic bar,Zirconia Ceramic Shaft, Ceramic Tube, 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, 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.
