In the manufacturing process of Faraday rotating magnetic sheets, the use of precise optical ultrasonic cleaning machines for cleaning is a very common and crucial step.

The cleaning of Faraday rotating magnetic discs is carried out at the stage when they are still independent raw materials or semi-finished products, with the aim of achieving extremely high surface cleanliness to ensure the performance of the final product.

Why can optical ultrasonic cleaning machines be used with confidence in production for cleaning

Faraday gyromagnetic sheets, as the core components of optical communication devices such as isolators and circulators, their performance directly depends on the flawless optical surface. Any tiny contaminants (such as dust, polishing residues, fingerprints) can cause light scattering, energy loss (increased insertion loss), and even device damage.

The precise optical ultrasonic cleaning machine is currently the most effective method to meet such demanding cleaning requirements.

The application of Vigot VGT-809FH optical ultrasonic cleaning machine in cleaning high-value optical components such as "Faraday spin discs" :

The core requirements for cleaning Faraday rotating magnetic discs are:

Ultra-high cleanliness, zero damage, and no water stains.

As a device for the high-end optical field, the VGT-809FH optical ultrasonic cleaning machine from Weigute has the following technical advantages:

1. Multi-band composite ultrasonic technology：

Low frequency (such as 28KHZ) : It has strong cavitation energy and is used for initial rough cleaning, effectively removing polishing powder and particles that are firmly adhered.

High frequencies (such as 68KHZ/132KHZ) : The cavitation bubbles are denser, the energy is milder, and the penetrating power is stronger. It can effectively remove sub-micron-sized tiny particles and greatly reduce the risk of "cavitation corrosion" on precision optical surfaces caused by cavitation effects. This is the key to ensuring the long-term reliability of the rotary magnetic sheet at high power.

2. Precision temperature control and heating system:

A stable temperature can ensure that the cleaning agent (such as professional optical cleaning solution) is always in the best active state, improving the cleaning efficiency and consistency. It is crucial for removing certain organic grease dirt.

3. High-quality materials and structural design：

High-grade stainless steel is corrosion-resistant, preventing the equipment itself from becoming a source of pollution, ensuring the cleanliness of the process cavity, and meeting the long-term reliability requirements for the production of optical communication devices.

Advantages of the VGT-809FH optical ultrasonic cleaning machine system from Weigute：

1.Integrated drying system：

For Faraday rotating magnetic sheets, drying without water stains is a hard requirement. This equipment integrates efficient air drying, heating drying or more precise slow pulling dehydration functions.

System value: Integrating multiple processes such as cleaning, rinsing, and drying into a single device or a compact workstation reduces the transfer of workpieces between processes, significantly lowers the risk of secondary pollution, and enhances overall production efficiency.

2. Process Optimization and Consistency：

Through the preset program, the operator only needs to press one button to complete the entire cleaning and drying process, reducing the reliance on personnel experience, lowering the risk of human operational errors, and ensuring product yield.

3. Data Traceability and Quality Management：

This is very helpful for meeting the quality traceability requirements of the optical communication industry. You can trace the cleaning history data of each batch of Faraday rotating magnetic sheets.

Core structural advantages of VGT-809FH optical ultrasonic cleaner：

1. Optimized ultrasonic oscillator layout and tank design：

The vibrators (ultrasonic transducers) are not simply pasted but are precisely calculated and arranged in a uniform layout, and may even be installed in a side-encircling manner.

Form a uniform and seamless sound field in the cleaning tank. This means that no matter where the Faraday rotating magnetic sheet is placed in the tank, it can be subjected to ultrasonic waves of consistent intensity, eliminating the phenomenon of uneven cleaning.

2. Full circulation filtration and liquid level management system:

It is equipped with an efficient built-in circulating pump and a precision filter (such as a pore size of 0.2-1μm) to continuously filter the cleaning solution.

It can remove the contaminant particles that fall off during the cleaning process in real time, preventing the workpiece from being "re-contaminated" during the cleaning. This is crucial for Faraday rotating magnetic sheets that require "zero particles".

3. Professional workpiece load-bearing design：

We offer specially designed workpiece/cleaning baskets, typically made of inert materials such as PTFE (polytetrafluoroethylene) or PFA.

Material compatibility: PTFE does not react with other chemicals and will not contaminate cleaning solutions or work.

Physical protection: The precise slot design can firmly fix each Faraday rotating magnetic plate, preventing them from colliding and rubbing against each other in the intense ultrasonic environment, thus avoiding scratches.

4. Rigorous sealing and corrosion-resistant structure:

The entire liquid path system (pipes, valves) and components in contact with water vapor are all made of high-standard corrosion-resistant materials. The slot cover is equipped with a sealing strip, effectively preventing the evaporation of water vapor and solvents.

Long service life and high reliability: Resistant to the erosion of various chemical cleaning agents, ensuring the long-term stable operation of the equipment in harsh environments.

Environmental protection and safety: Prevent the leakage of harmful gases, protect the health of operators and the production environment.
