Product Introduction
This series of vacuum diffusion welding equipment is specifically designed for the high-molecular diffusion welding process of metal electronic products and structural components such as aluminum, red copper, and stainless steel. The equipment applies precise and controllable pressure and temperature to the workpiece in a high vacuum environment, allowing diffusion and mutual dissolution between atoms at the contact interface to achieve reliable solid-state connection without solder or intermediate layers. This equipment features high vacuum, no volatile pollution, uniform temperature field, arbitrarily adjustable pressure, and a fully automatic control system. It is particularly suitable for enterprises' needs for batch and high-consistency diffusion welding production, making it a preferred equipment in the field of precision metal connection.
Technical Features
High vacuum environment: High ultimate vacuum effectively removes interface oxide films and gases, promotes atomic diffusion, and achieves a pure and dense weld joint.
No volatile pollution: No solder, flux, or harmful gases or residues are produced throughout the process, ensuring workpiece cleanliness and complying with environmental requirements.
Excellent temperature field uniformity: Optimized heater layout and multi-zone temperature control ensure uniform temperature distribution within the furnace, guaranteeing consistent welding quality for large-sized or multiple workpieces.
Pressure arbitrarily adjustable: Adopts servo or hydraulic pressurization system, with continuously adjustable pressure and high control accuracy, adapting to welding needs of different materials and areas, avoiding crushing or poor contact.
Fully Automatic Control System: Programmable setting of process parameters such as temperature, pressure, vacuum, and time, one-key operation, real-time curve recording, reducing manual intervention, and improving batch stability.
Safety interlock protection: Integrated multiple protections such as over-temperature, over-pressure, abnormal water pressure, and vacuum pump interlock ensure safe and reliable equipment operation.
Application Fields
Diffusion welding of electronic products made of aluminum and aluminum alloys: such as diffusion welding of aluminum shell battery covers, power module heat dissipation substrates, waveguide components, etc.
Red Copper/Oxygen-free copper components: Used for high-reliability connections of vacuum electronic devices, vacuum tubes, water-cooled copper electrodes, superconducting cavities, etc.
Precision stainless steel components: Such as sensor diaphragms, micro bellows, instrument casings, and chemically resistant structural components.
Dissimilar Metal Combination: Aluminum-Copper, Aluminum-Stainless steel, titanium-Diffusion welding of dissimilar material transition joints and composite components such as stainless steel.
Powder metallurgy and multi-layer structure: Diffusion and densification of pre-formed metal powder compacts, or overall forming of microchannel plates and multi-layer fin structures.
Product Advantages
Excellent welding quality: The joint has no cast structure, pores, or inclusions, with strength close to the base material, and the surface is bright and free of oxidation during vacuum welding.
Suitable for batch production: Large-volume furnace chamber combined with multi-station pressurization tooling allows for welding multiple sets of workpieces at once; fully automatic program operation effectively reduces the cost per piece.
Wide process window: Pressure, temperature, and holding time are independently adjustable, allowing the same equipment to cover diffusion welding processes for various materials from soft aluminum to stainless steel.
Clean and environmentally friendly workpiece: No solder or cleaning process required, avoiding chemical pollution; sealed vacuum system with no emissions, meeting clean workshop and green manufacturing standards.
High equipment reliability: Designed for continuous production, with redundant configuration of key components and simple maintenance; user-friendly interface with a low operation threshold.
