25kg Powder Magnetron Sputtering Coater

I. Equipment Introduction

The 25kg powder magnetron sputtering coating instrument is a large-capacity vacuum PVD coating equipment specially designed for powder particles. It is developed for a single loading capacity of 25kg powder materials. Based on the physical vapor deposition principle of magnetron sputtering, it is equipped with a rotating chamber and powder tumbling vibration mechanism to keep powder particles continuously rolling without dead angles. Dense nano-films of metals, alloys, ceramics and oxides can be uniformly deposited on the surface of each powder particle.

The whole process is carried out in a fully sealed high-vacuum environment, featuring dense films, controllable thickness, uniform coating and no agglomeration. It is suitable for small-batch pilot tests and modification preparation of new materials. Developed and manufactured by Zhengzhou CY Scientific Instruments, it meets the demands of laboratory research and small-batch trial production simultaneously.
