General introduction of PAIJIN Vacuum furnaces

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.

Processes
Paijn 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:
Annealing
Tempering
Brazing
Sintering
Hardening
In Vacuum and Atmosphere conditon.

By adding some fuction parts, it will realize or strengthen its ability in
Carburizing
Debinding
Nitriding
Oil hardening
Low 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.
 

Payment terms and ordering process:
We accept paymen by TT:
20% TT in advance, 50%TT after confirmation of drawings and 30% TT after PSI but before loading on board

or 100% LC at sight.
Ordering Process:
Confirm user's technical specification requirement----Quotation with specification---confirm specification and other terms---sign contract--first payment or Issurance LC----Drawing confirmation----Manufacturing---Preshipment inspection and training---Shipment----field service like installation and commission(optional)---after sales service


Produce time and delivery schedules
According to different model and requirements about the furnace, It need about 3-8 monthes for the produce of the furnace.
After the finish of the furnace, User's representatives are invited to visit our factory and inspect the furnace in our factory.Meanwhile,we can supply 1-2 weeks free training courses for them in our factory.
After the pre-shipment inspection and final payment, we will arrange the shipping within one week.



Quality Control:
Quality is the spirit of the products, is the key point decide a factory's future.Paijin take quality as the most priority issues in our daily work.To ensure the good quality of our products, we paid much attention on 3 aspects.

1. 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.
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.

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.
