Vacuum heating - Import export

We use this vacuum degasser to clean all kinds of products before do the coating. This degas chamber is venting the gas,air and other impurities through putting in the heated N2. This vacuum degasser will greatly shorten the vacuum time, reduce the oxygen corrosion, protect the machine and prolong the life time of the equipment. It enhances the adhesion of the film in the products.

Introduction: 303 through  hardened screw, has better corrosion resistance  Tail annealing treatment, greatly improving the toughness of the screw CNC full grinding thread, tooth root top concentric and tooth bottom flatness high precision, can reduce the shear heat. Application: Low acid plastic + GF15 following, such as PMMA, PC and so on Temperature ≤400 ℃ Optical lenses, cosmetic packaging and so on Materials and Process: Material origin: Japan The main components: Cr, V, Mo and so on Heat treatment: vacuum quenching, hardness HRC48-52. (1020-1050 vacuum quenching, high temperature tempering 550-570 more than three times, the rear high temperature annealing softening treatment) Surface treatment: PVD coating (TiN, TiCN, TiAlTiN)

Boron nitride can be long-term used at 1800 degrees under vacuum atmosphere. With gas protection, Boron Nitride can be used at 2100°. Boron Nitride is with high thermal shock resistance, no cracks under extreme cold & high temperature. If you take out Boron Nitride from 1000 degree furnace and colding it within short minutes. It still won't break even repeat this test with 100 times. > Matching materials: BN-99, BN-AL > Advantages: high temperature resistance (2000℃), thermal shock resistance, high electrical breakdown strength (3 -4 times that of alumina), carbon atmosphere corrosion resistance is much stronger than alumina > Used for polysilicon ingot furnace, graphitization heat treatment furnace, vacuum sintering furnace, atmosphere furnace ect. Grades 5 grades of boron nitrides are involved in Boron Nitride product series. * BN99 ● CABN ● ALBN ● ZRBN ● ZABN ● SB
