• +1. Equipment overview This equipment is a vertical lifting vacuum atmosphere integrated furnace, integrating two processes of low-temperature degreasing and high-temperature sintering, without transferring workpieces, and completing the entire process of ceramic billet from removing binder to compact sintering in a single unit. It is specially designed for HTCC, MLCC, ceramic metallization, and MIM metal parts, supporting vacuum, nitrogen, dry/wet hydrogen multivariate atmosphere, and taking into account laboratory small-scale trials and enterprise mass production. Second, the core technical parameters temperature system is 1750 ℃ higher, long-term use ≤ 1650 ℃; molybdenum-lanthanum alloy wire surround heating, temperature control accuracy ± 1 ℃, furnace temperature field uniformity ≤ ± 3 ℃; multi-segment PID programmable curve, low-temperature slow glue discharge, high-temperature sintering segmentation process can be accurately set. Vacuum and atmosphere cold limit vacuum < 50Pa; rotary inlet, support nitrogen, hydrogen, wet hydrogen automatic switching; closed-loop pressure control, furnace pressure ≤ 40KPa, fluctuation ≤ ± 1KPa; furnace oxygen content ≤ 0.1PPM, dew point - 60 ~ 60 ℃ automatic control. Furnace body specifications Two standard furnaces: Φ200 × 300mm and 500 × 500mm; the whole machine power is divided into 28KW and 120KW, and three-phase 380V power supply. The organic volatiles produced by the eco-friendly tail gas treatment and glue discharge can be condensed and collected or ignited and burned without exhaust gas pollution. 3. Structure characteristics of the whole machine Hydraulic/screw lifting furnace table with vertical lifting sealing structure,
• +Convenient loading and unloading; double-layer air-cooled sealed furnace shell, low temperature of the shell, long service life of the seal; high-purity alumina hollow ball brick furnace, high temperature resistance, no powder, high thermal efficiency. The five-sided uniform heat field (low-temperature type matching) box type is heated by the front, rear, left and right bottom five-sided resistance wires, with a four-angle preheating air supply system, the air flow in the furnace at the low-temperature glue discharge stage is fully circulated, and there is no residue in the decomposition of the binder. Integrated process design (core advantages) The same furnace is first low-temperature and slowly discharged, and then directly heated and sintered at high temperatures. There is no need to transfer from the furnace to avoid bumping, oxidation, and secondary pollution of the workpiece, which greatly improves the yield of the finished product. Automatic PLC touch screen control system: complete set of glue removal, heating, heat preservation, atmosphere switching, cooling program one-click operation; automatic recording of temperature, vacuum, pressure, dew point data, support curve export and archiving; equipped with remote monitoring function. Full link interlock over-temperature, broken coupling, insufficient water pressure, over-pressure, hydrogen leakage, fault shutdown sound and light alarm; over-pressure automatic pressure relief, explosion-proof structure for combustible atmosphere. 4. The advantage yield of the core products greatly improves the airtight atmosphere throughout the whole process, the workpiece does not contact with air, there is no residual carbon in the glue discharge, no oxidation in the sintering, and no cracking, pores, and black spots. An energy-saving and space-saving device replaces the separate rubber discharge furnace + sintering furnace, eliminating the energy consumption of workpiece transfer and secondary heating, and reducing the floor area of the workshop. The atmosphere is precisely controlled, dry and wet hydrogen is automatically switched, low oxygen sealed environment,
• +Suitable for ceramic metallization, superalloy, cemented carbide and other demanding processes. The environmentally friendly and standard-compliant condensing/combustion dual-mode tail gas treatment ensures harmless emission of organic waste gas and meets the environmental protection standards of the factory. Simple operation can copy multiple process curve storage calls, newbies can also repeat production stably, and the data can be traced back to the whole process. V. Applicable industries and processes Electronic ceramics: HTCC high temperature co-firing, MLCC, LTCC, piezoelectric ceramics, ceramic filter degumming sintering; powder metallurgy: MIM metal injection molding, carbide degreasing sintering; new materials: zirconia, aluminum oxide, aluminum nitride, 3D printing ceramic billet integrated heat treatment; scientific research and experiments: all kinds of ceramics, metal powder atmosphere reduction, degreasing, dense sintering. 6. Supporting and after-sales factory equipped with a full set of pipelines, seals, operating instructions, and certificates of conformity; the whole machine is guaranteed for one year, except for consumables such as molybdenum wires, thermocouples, and seals; fast response to faults, and free upgrades of accessories and software for life.
