Relative information

Hi,my friend, thanks for checking Paijin Vacuum furnaces. I will show you why our products are  your best choose.

Technical advantages:

1. Energy saving: By using our self-owned registered patented technology of energy saving, our furnaces saves 20%-40% energy than other brands in heating. Reduces muh cost.
2. High Intelligent Control system:All our furnaces are equiped with our high intelligent control system, it can realize one button operation by the recorded data and record the processs in Computer.
3. Advanced Voltage control technology, lower current in same power to avoid the melting of cables, and raise safety level.

In this rating system, it's not only the skills, but also rate in responsibility and error rate, executive power etc. By this way, workers in our factory are willing to do the best in his work.And strictly follows the quality management rules.
2. Best materials and components: We only purchase the best materials on market, we know that saves 1 dollar in material would cost 1000 dollars in final. The key parts like electric components and pumps are all brand products like Siemens, Omron,Eurotherm, Schneider etc. For the other parts made in China, we choose the best factory in industry and signed product quality guranntee contract with them,to ensure every component every parts we use in the furnace is the best quality products.
3. Strict Quality management: We have 8 quality check points in the processes of furnace producing, Examination in each check point is carried by 2 workers and 1 factory manager is responsible for it. In these check points, materials and components, and every aspects of the furnace are double checked to ensure its quality. At last, before the furnace leaves factory, it should be final checked with heat treatment experiments.

Packages and Shipping:

We have much experience in the packages and shipping, our furnaces are usually shipped by rail or by sea. Sometimes small parts my shipped by air. The main body will be fixed in the container by steel ropes and other parts will be packaged in wooden cases.
