In the chain of industrial manufacturing, there is an invisible but crucial link – precision cleaning.
Many people don’t know that a qualified automobile transmission gear, aerospace engine part, or even mobile phone glass must go through a strict cleaning process before it can flow into the next link. The fully automatic ultrasonic cleaning machine is the core equipment that supports this link.
For manufacturing bosses, the pain points in the cleaning process are never trivial: batch workpieces cannot be washed clean and are rejected by downstream customers; manual cleaning efficiency is low and cannot keep up with production capacity; parts with sensitive materials are scratched after being washed out and are directly scrapped; environmental protection standards are not met and face production suspension and rectification.
Each of these problems can cause a company to suffer heavy losses, and even lose long-term large customers.
Today we will start with several real industrial scenarios to see how fully automatic ultrasonic cleaning machines can solve these pain points and become the invisible guardian behind manufacturing companies.
Invisible industrial cleanliness hides the bottom line of trust of downstream users
In the auto parts industry, cleanliness is directly related to the performance and safety of the entire vehicle.
For example, if the motor casing of a new energy vehicle is not thoroughly cleaned of oil stains and metal debris, it will cause increased wear and tear during operation of the motor, and even cause failure, ultimately affecting the reputation of the entire vehicle.
Many small and medium-sized auto parts factories initially used traditional spray cleaning machines or manual scrubbing. Not only was the efficiency low, the oil stains in the blind holes could not be washed out at all.
Downstream OEMs come for random inspections. Once they find that the cleanliness is not up to standard, the entire batch of goods will be returned directly and liquidated damages will be deducted. The one-time loss may be hundreds of thousands.
The advantage of the fully automatic ultrasonic cleaning machine is that it can use high-frequency ultrasonic vibration to completely peel off the oil dirt and debris in blind holes and gaps. Coupled with the integrated process of spraying, drying and filtration, it ensures that the cleanliness of each workpiece reaches the standard, avoiding the risk of returns and breach of contract at the root.
In the new energy auto parts workshop, the efficiency revolution of fully automatic ultrasonic cleaning
The biggest problem faced by a large new energy auto parts group in Jiangsu was that the production capacity could not keep up.
Their motor casings and battery casings are produced in batches, and tens of thousands of them are processed every day. Traditional cleaning equipment can wash up to 3,000 pieces a day, and the workers can’t catch up with the orders even if they work two shifts.
Later they chose an advanced fully automatic through-type ultrasonic cleaning line. This equipment uses mesh belt conveying, multi-tank ultrasonic + spray + drying + filtration integration, and is also equipped with 40KHz/80KHz dual-frequency ultrasonic.
After being put into production, the production capacity was directly increased by three times, and more than 9,000 pieces can be processed in a day, so there is no need to worry about catching up on orders.
More importantly, the yield rate has increased from 92% to 99.5%, and the hundreds of workpieces that had to be reworked every day have almost disappeared.
Based on the cost of 50 yuan per workpiece, nearly one million can be saved in rework costs alone in one year, not counting the revenue from additional orders received due to increased production capacity.
Note: Different workpieces have different materials, sizes, and cleaning requirements. The production capacity data is for reference only, and the actual situation needs to be determined according to the customized plan.
“Zero Damage” Cleaning Code for Aviation Precision Parts
Precision parts in the aerospace field, such as titanium alloy aircraft engine parts and aerospace sensors, have very strict cleaning requirements: they must achieve aviation-grade cleanliness without causing any scratches or damage to the parts, because even micron-level scratches may affect flight safety.
When selecting cleaning equipment, a company compared multiple manufacturers and finally selected a customized large-scale fully automatic ultrasonic cleaning machine.
This equipment is made of 316L stainless steel, equipped with 28/40/80KHz multi-frequency ultrasound, and also adds an intelligent filtration circulation system.
In actual use, this equipment can not only thoroughly clean the oil stains and metal debris on the surface and gaps of the parts, but also ensure that the titanium alloy parts are not damaged. It has successfully passed the relevant acceptance and has been supplied stably for many years without any quality problems.
For aerospace companies, the stability and reliability of equipment are more important than anything else. Once a failure occurs, it may affect the progress of the entire project. The equipment has a long average trouble-free operation time, which can fully meet the needs of such high-threshold customers.
Watermark-free clean protection of electronic optical components
Workpieces in the electronic semiconductor and optical industries, such as PCB boards, optical lenses, and mobile phone glass, not only require high cleanliness, but also must not have any watermarks or scratches, otherwise the products will be scrapped directly.
The cleaning equipment used by a large factory in the Yangtze River Delta often left watermarks after cleaning, and the yield rate has never been improved.
Later they introduced advanced through-type ultrasonic cleaning lines and drum-type ultrasonic cleaning machines. This equipment uses mesh belt conveying, multi-stage ultrasonic + spray + hot air drying, and is also equipped with an RO water filtration system.
After being put into production, the production capacity reached 5,000 pieces/hour, the yield rate increased directly to 99.8%, and there was no watermark problem again.
For electronic optics companies, every 0.1% increase in yield can save hundreds of thousands of costs a year.
This equipment can not only improve the yield rate, but also achieve 24-hour continuous and stable operation, fully meeting the needs of mass production.
The hardware bearing factory’s 24-hour continuous operation confidence
A large local bearing manufacturing group in Zhangjiagang produces deep groove ball bearings and roller bearings that are supplied in batches to major domestic machinery companies, processing tens of thousands of bearing rings every day.
The cleaning equipment used before often broke down. Once it stopped, the entire production line had to stop, causing huge losses.
They chose a special through-type ultrasonic cleaning machine for bearings. This equipment adopts the design of upper and lower dual ultrasonics, high-pressure spray, and hot air drying. It can not only thoroughly clean the oil stains on the inner and outer rings of the bearings, but also achieve 24-hour continuous and stable operation.
After it was put into production, the production capacity increased by 2 times, and the defective rate dropped to less than 0.3%. Moreover, this equipment has been in service for more than 10 years with almost no major failures.
For hardware bearing factories, the durability and stability of equipment are directly related to production efficiency, and this equipment can fully meet such high-intensity production needs.
13 years of technological accumulation of a certain company: from single machine to complete line customization
A certain company has been deeply involved in the field of industrial ultrasonic cleaning equipment for 13 years. It is a national high-tech enterprise with ISO9001 quality management system certification, as well as formal industrial production qualifications and environmental impact assessment compliance certificates.
Their core products include not only fully automatic ultrasonic cleaning machines (single tank/multi tank/gantry type/robot type), but also through-type ultrasonic cleaning lines, hydrocarbon vacuum cleaning machines, high-pressure spray cleaning integrated machines, and special cleaning equipment for auto parts, hardware, electronics, optics and other industries.
More importantly, they have strong non-standard customization capabilities and can quickly design complete line solutions based on the customer’s workpiece size, production capacity, and process requirements.
Whether it is large-volume new energy auto parts or material-sensitive aviation precision parts, they can provide exclusive cleaning solutions.
Full-process service: Let customers not worry about cleaning, operation and maintenance
When purchasing cleaning equipment, many manufacturing companies are not only concerned about the performance of the equipment, but also worry about subsequent operation and maintenance issues.
The company provides full-process services from solution consultation, process samples, equipment installation, debugging and training to after-sales maintenance, with 24-hour local response and remote + on-site dual-line support.
For example, a company in Zhejiang was not familiar with the cleaning process at the beginning. The company’s technical staff came to do process samples and determined the best cleaning plan. They were then responsible for installation and commissioning, and also trained the workers.
Later, the customer repurchased three production lines because he trusted their services.
For enterprises, with such a full-process service, they no longer have to worry about problems with equipment installation and debugging, or that no one will repair later failures, and can focus more on production.
Compliance qualifications: Building a solid defense line for the safety and quality of industrial equipment
Under the current environmental protection policies, the compliance of industrial equipment is becoming more and more important.
The company’s equipment not only complies with ISO9001 quality management system standards, but also passes environmental assessment compliance, which can help companies meet environmental protection requirements and avoid the risk of production suspension and rectification.
For example, a well-known auto parts precision manufacturing company in Shanghai was previously rectified due to environmental issues. Later, it chose the company’s multi-tank fully automatic ultrasonic cleaning machine + hydrocarbon vacuum cleaning machine. This equipment achieved zero emissions and low VOCs, successfully passed the environmental acceptance, and no environmental problems have ever occurred again.
In addition, the company has participated in government and large-scale enterprise bidding projects three times, and its product performance and services have been officially recognized, which also provides reliable guarantee for customers’ choices.
