In high-precision manufacturing fields such as superconducting materials, precision wires, and electronic wires, indium coating of superconducting wires is a core process ensuring the wire's conductivity, thermal conductivity, and bonding stability. Superconducting wires have intricate structures and require extremely high processing precision. Traditional manual indium coating and ordinary indium coating equipment suffer from numerous problems, including uneven coating, weak adhesion, unstable temperature control, and low operating efficiency, easily damaging the superconducting wire substrate and affecting the wire's superconducting performance and lifespan. Addressing these pain points in the industry's superconducting wire indium coating process, Shanghai Hanling has exclusively developed an ultrasonic superconducting wire indium coating machine. Utilizing mature ultrasonic physical coating technology and standardized, high-precision equipment parameters, it is specifically customized for superconducting wires, achieving non-destructive, uniform, firm, and efficient precision indium coating processing, providing a reliable process solution for mass production of superconducting wires.
The equipment is equipped with a 70W rated power, providing stable and balanced power output, perfectly suited to the precision indium coating conditions of superconducting wires. Compared to the drawbacks of low-power equipment (insufficient power and poor coating adhesion) and high-power equipment (potential damage to delicate wires), 70W power is the optimal power configuration for indium coating of superconducting wires. The power output is ample yet gentle, meeting the power requirements for full melting and uniform spreading of the indium material, ensuring a tight bond between the coating and the wire substrate, while avoiding deformation and damage to the superconducting wires due to power overload. It is suitable for routine precision indium coating operations on various specifications of superconducting wires, balancing processing quality and workpiece integrity.
The equipment adopts the industry-standard 28kHz operating frequency for precision coating, ensuring stable vibration and high operational precision. This frequency has been adapted through extensive industrial testing to suit the material characteristics of superconducting wires and the indium coating process requirements. The stable high-frequency ultrasonic vibration drives the molten indium material to penetrate and spread uniformly, eliminating coating buildup and thickness variations that occur in traditional processes. Stable high-frequency vibration allows indium molecules to fully fuse with the wire surface, significantly improving coating adhesion and uniformity, fundamentally ensuring the stability of the conductivity and superconductivity of the superconducting wires, and effectively avoiding product performance failures caused by indium coating defects. The equipment is equipped with a wide-range, precise temperature control system (150-400℃) to adapt to different indium melting requirements and superconducting wire processing standards. The temperature control range covers multiple process modes, including low-temperature slow indium melting and high-temperature rapid coating. The heating rate is uniform with minimal temperature error, and the temperature can be freely adjusted according to the wire material and indium layer thickness requirements. The low-temperature mode is suitable for fine, thin-walled superconducting wires, avoiding high-temperature damage to the substrate performance; the high-temperature mode is suitable for thick-layer indium coating and high-adhesion processing requirements. The temperature is controllable and adjustable throughout the process, eliminating problems such as localized overheating and wire burn-out, and insufficient temperature leading to weak coating adhesion, adapting to diverse superconducting wire processing scenarios.
Regarding core coating precision, the equipment supports 3-20μm micrometer-level working amplitude adjustment, precisely controlling the indium coating accuracy and coating effect. Small amplitude enables ultra-thin, fine precision coating, meeting the thin-layer indium coating requirements of micro-superconducting wires and high-precision superconducting components; large amplitude enhances the indium spreading effect and improves coating adhesion density, adapting to industrial-grade heavy-duty superconducting wire processing. Micron-level amplitude control ensures uniform and smooth coating with every operation, eliminating ripples, blind spots, and the risk of peeling, perfectly meeting the ultra-high precision production standards of superconducting wires.
The equipment adopts a standard industrial power supply configuration of 220V±10%, 40/60Hz, and 4A, compatible with the conventional power supply environment of domestic factories and workshops. No circuit modifications or dedicated power supply equipment are required, making installation convenient and plug-and-play, effectively reducing equipment deployment costs and maintenance difficulties for enterprises. The equipment also features freely switchable intermittent and continuous working modes, offering extremely high functional adaptability. The continuous mode is suitable for large-scale standardized superconducting wire mass production, ensuring stable and continuous operation and significantly increasing capacity; the intermittent mode is suitable for new product prototyping, small-batch customization, and precision sample processing, flexibly adapting to the entire process of R&D, pilot production, and mass production, meeting the diverse production needs of enterprises.
Overall, the Shanghai Hanling Ultrasonic Superconducting Wire Indium Coating Machine boasts scientifically precise parameter configurations and stable and reliable performance, specifically addressing industry pain points such as low indium coating precision, fragile materials, poor adhesion, and weak adaptability in superconducting wires. Leveraging its advantages of stable power, standard high frequency, precise temperature control, micron-level amplitude, and dual operating modes, the equipment achieves a standardized, precise, and efficient upgrade of the indium coating process for superconducting wires. It is widely used in the fields of superconducting material research and development, precision electronic wires, and high-end conductive wire manufacturing, making it the preferred professional equipment for precision indium coating processing of superconducting wires.
