The main body adopts high temperature resistant material, which satisfies the carbonation heating process of thin and medium and thick granule WC powder and composite material.4.Adopt the combination mode of temperature control.5.Graphite heat shield, graphite heating element,360-degree surround radiant heating.6.A variety of condensation trapping methods to reduce unit pollution7.Nitrogen purging system has better insulation and degreasing.8.Patented insulation technology to ensure the long-term use of heating body9.Exhaust gas combustion and filtration system meets emission standardStandards:DIN 17052 - 1 "Heat treatment furnaces - Part 1: Requirements for temperature uniformity"EN 60519 -2 "Safety in electroheat installations - Part 2: Particular requirements for resistanceheating equipment"AMD2750D "AEROSPACE MATERIAL SPECIFICATION"NFPA86D "Standard for Ovens and Furnaces"GB/T 16876 "Vacuum test standard for double wall equipment"GB/T 10066.1 " Test methods for electroheating and electromagnetic processing installations"GB/T 9452 "Testing Method For Working Zone Of Heat Treatment Furnace"Product ParametersStandard model specification and parametersModelPJ-SJ336PJ-SJ447PJ-SJ449PJ-SJ4411PJ-SJ5518Effective Hot Zone LWH (mm)300*300*600400*400*700400*400*900400*400*1100500*500*1800Load Weight(kg)120200300400800Maximum Temperature(oC)2800Temperature control accuracy(oC)±1Furnace temperature uniformity(oC)±5-20Work Vacuum Degree(Pa)4.0 * E -1Pressure raise rate (Pa/H)≤ 0.5Debinding rate>97.5%Debinding methodN2 in negative pressure,H2 in atmosphereInput gasN2,ArCooling SpeedadjustableCooling methodVacuum cooling,Pressure cooling,Forced pressure coolingSintering methodVacuum sintering,partial pressure sintering,pressureless sinteringFurnace structureHorizontal, single chamberFurnace door opening methodHinge typeHeating elementsGraphit heating elementsHeating chamberComposition structure of Graphit hard felt and soft feltThermocoupleC TypePLC & Electric elementsSiemensTemperature controllerEUROTHERMVacuum pumpMechanical pump and roots pumpCustomized optional ranges Maximum temperature1300-2800 oCMaximum temperature degree6.7 * E -3 PaFurnace structureHorizontal,Vertical, single chamberDoor opening methodHinge type, Lifting type,Flat typeHeating elementsGraphit heating elements, Mo heating elementsHeating chamberComposed Graphit felt, All metal reflecting screenVacuum pumpsMechanical pump and roots pump; Mechanical, roots and diffusion pumpsPLC & Electric elementsSiemens;Omron;Mitsubishi;SiemensTemperature controllerEUROTHERM;SHIMADENRelative informationGeneral introduction of PAIJIN Vacuum furnacesHi,my friend, thanks for checking Paijin Vacuum furnaces. I will show you why our products are your best choose.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 ZonesGraphite 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 ZonesIf 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 ConstructionsWe 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 boardor 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 serviceProduce time and delivery schedulesAccording 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.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 GuaranteeWe 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. Company Profile
