It boasts a powerful 45kW cooling fan and 300kW total power rating with internal circulation cooling for rapid temperature reduction. The system is supported by a fully automated electronic control unit with paperless recording, vacuum interlocks, safety systems (over-temp, water cut-off), and real-time diagnostics. Additional features include a stainless-steel water cooling system, air source treatment unit, nitrogen inflation and pressure control, and a manual loading trolley. Built for precision, durability, and energy efficiency, the VF1300-1288 is ideal for industries requiring high vacuum integrity and temperature accuracy. With a manufacturing lead time of 4.5 months and a 12-month warranty, the equipment includes installation, commissioning, operator training, full technical documentation, and lifelong support.
Main application areas of vacuum brazing furnace
Aerospace Industry
Vacuum brazing is a vital process in the aerospace industry, where precision, strength, and reliability are non-negotiable. It is extensively used in the production of turbine blades, heat exchangers, fuel system components, jet engine parts, and structural assemblies that must withstand extreme temperatures and mechanical stress. The process enables the joining of dissimilar metals and intricate assemblies without the use of flux, eliminating the risk of contamination and ensuring the highest levels of cleanliness. This is crucial in aerospace applications, where even microscopic impurities can compromise performance or safety.
Automobiles Industry
Vacuum brazing is essential in the manufacturing of a wide range of automobile components that demand strong, precise, and contamination-free joints. It is commonly used in parts such as oil coolers, heat exchangers, radiators, fuel system components, transmission parts, and EGR (Exhaust Gas Recirculation) coolers. Additionally, vacuum brazing is critical for joining aluminum cold plates, liquid cooling heat sink plates, carbide tipped gear hobs, laminated aluminum evaporators, high voltage DC relays, battery coolers, and aluminum alloy chassis.
Medical Industry
Vacuum brazing plays a crucial role in the manufacturing of various high-precision medical components. It is widely used in the production of surgical instruments, dental tools, orthopedic implants, and electronic medical devices such as pacemakers and defibrillators. The process allows for the joining of dissimilar metals and complex geometries without introducing impurities, making it ideal for components that require high structural integrity and cleanliness. It ensures strong, leak-tight joints in medical assemblies, which is essential for patient safety and device performance.
Semiconductor Industry
Vacuum brazing is essential in the semiconductor industry, where ultra-clean, high-precision bonding is required for the fabrication of advanced electronic components. It is widely used in the production of heat sinks, sensor housings, wafer processing tools, and vacuum chamber assemblies. The process enables the joining of dissimilar metals and complex structures without introducing flux or contaminants, making it ideal for maintaining the ultra-high vacuum and purity levels demanded in semiconductor environments. Vacuum brazing ensures superior thermal conductivity, structural integrity, and leak-tight sealing—critical for temperature-sensitive and high-performance semiconductor devices.
Tools and dies Industry
Vacuum brazing is widely applied in the tools and dies industry for manufacturing high-performance components such as cutting tools, grinding wheels, stamping dies, extrusion dies, and injection molds. It is especially valuable in the production of diamond tools, including diamond saw blades, grinding wheels, rollers, drill bits, engraving knives, beads, and grinding heads, used across woodworking, stone processing, glass cutting, and construction industries. These vacuum-brazed tools are crucial across sectors such as automotive, aerospace, electronics, metallurgy, geology, military, and infrastructure, where precision, strength, and durability are essential.
