Relative information
Technical advantages:
- 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.
- 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.
- Advanced Voltage control technology, lower current in same power to avoid the melting of cables, and raise safety level.
ProcessesPaijn vacuum furnaces are basically composed by Furnace body, heating system, vacuum system, gas recharge system and control&measure systems.A standard vacuum furnace would able to used for the basic processes like:AnnealingTemperingBrazingSinteringHardeningIn Vacuum and Atmosphere conditon.By adding some fuction parts, it will realize or strengthen its ability in CarburizingDebinding NitridingOil hardeningLow temperature difference brazing (≤±3ºC)Hot zone materials:
Graphite Hot Zones
Graphite hot zones are long-lasting and can deliver excellent ROI. They are robust, economical to repair and incorporate hearth designs with high creep strength.
All-Metal Molybdenum Hot Zones
If your process is susceptible to graphite contamination, a molybdenum hot zone can meet your needs. Our moly hot zone elements feature a "double-U" profile which makes them easy to install and replace.
Custom Constructions
We offer custom hot zone construction such as graphite insulation with moly heating elements, for applications with unique requirements.
- Most important: Human. Human is the most important point in every work. We have complete training courses for every new worker, and we have rating system to rate every worker to a level (junior, middle, high), different level workers are apponted to different jobs with different salary. 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.
- 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.
- 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.
After sale service:
a. Quality Guarantee
We supply a guarantee period of 12 months reckoning from the date of commissioning of the furnace against all defects or failures due to faulty design, material, or workmanship. But within 18 monthes after the furnace is deliveried from our factory.
b. Backup support for provisioning of spares for 15 x years.
c. Technical Support:We supply 15 years free online technology support for our furnaces.
