Vacuum sintering furnaces - Import export

Single-stage rotary vane pumps from Pfeiffer Vacuum have long been some of the most widely used products for processes in the low and medium vacuum range. Their long life and pumping speed, irrespective of the gas used, are the outstanding properties of this pump. Typical applications are found in widely ranging sectors: — Analytics (mass spectrometry, electron microscopy) — Coating technology (surface protection, decorative films, display units, monitor screens) — Vacuum metallurgy (vacuum soldering, vacuum sintering, vacuum alloys, furnace construction) — Leak detection technology (vacuum systems, automotive tanks, airbag cartridges, packaging) — Lighting industry (light bulb manufacture) — Drying industry (vacuum drying, transformer drying)

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

The SSH is a standardized vacuum-pressure sintering furnace for economic production of hardmetal (cemented carbide) parts. It combines the universal application of dewaxing (debinding), vacuum-sintering and isostatic pressing up to 60 bar overpressure in one process. Based on PVA TePla's leadership in production of Sinter HIP furnaces for hardmetal applications, the SSH furnace gives you a most affordable and economic access to this leading technology. Applications: Dewaxing (Debinding), vacuum-sintering, isostatic pressing Customer Benefits: • High product quality by excellent temperature homogeneity • Elaborated safety system for reliable and full-automatic operation • Short dewaxing and cooling times • Short installation and ramp-up times, all pre-tests and qualifications done at PVA site • Proven design and performance • Short delivery time due to pre-production • High cost effectiveness • High energy efficiency • Low gas consumption

In the WTH 200.2, the following materials can be reliably brazed with active materials in a high vacuum. PCD (polycrystalline diamond) MKD (monocrystalline diamond) CVD diamond (chemical vapour deposition) PCBN (cubic boron nitride) and Hard metals as well Ceramics In the high-vacuum furnace WTH 200.2, our customers manufacture indexable inserts, dressing wheels, rotating tools and turning tools with blades made of natural diamond or MKD for polish turning. The vacuum brazing is flux-free. In the so-called active brazing process, titanium allows wetting of the surfaces. While cemented hard metals can also be inductively brazed, diamonds, CVD and ceramics must be actively brazed in a vacuum. When brazing PCD and PCBN, not only the hard metal substrate but also the PCD or PCBN layers are wetted.
