Vacuum brazing - Import export

NKCG engineering configures solution optimized for the specific heat treatment process using FEA/CFD and other advanced tools. NKCG systems are being used in various applications such as Carburizing | LPC | Sintering | PVD/CVD | Vacuum Brazing | Inert gas and vacuum atmospheres

The Controlled Atmosphere Brazing (CAB) and Vacuum Furnace Tracker Systems from Fluke Process Instruments feature the Datapaq TP6 data logger, a reflective or sealed for CAB thermal barrier, thermocouples and our intuitive Insight™ Software to create a complete solution. The CAB Furnace Tracker Systems featuring the TB4000 & TB4002 thermal barriers operate in environments up to 800°C (1472°F) and are designed for frequent use in the aggressive atmosphere present in this process. The Vacuum Brazing Furnace Tracker Systems, which include the VB1150 & VB1151 thermal barriers, make use of reflective plate technology to eliminate the need for insulation and ensure that out-gassing from the system is minimized so production is not disrupted when profiling. Both systems can be used to conduct temperature uniformity surveys (TUS) in compliance with CQI 29. Data Logger The Datapaq TP6 is the perfect solution for the most demanding high-temperature profiling applications

The Freek-MicroCoil 1.3 x 2.3 mm used in the "Brazed-Together" energy-saving nozzle heater is wound tightly onto a precision tube with good thermal conductivity and encapsulated and thermally insulated by means of an outer housing. For even more reliable heat transfer, the heater can optionally be vacuum brazed. The "Brazed Together" design combines many advantages: high accuracy, good heat conduction, high power density, mechanical stability and, last but not least, up to 20% higher energy efficiency. Freek is one of the technology leaders in the field of hot runner heating and supplies the who's who of the industry. Energy efficiency is one, if not the central innovation topic here. Manufacturers of high-cavity PET hotrunners and moulds in particular benefit from the BT nozzle heaters, and in several ways: because the less energy that is put into the system, the less energy has to be taken out on the cold side, the mould. This saves even more energy and shortens the cycle time.

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.
