Focusing on Cleanliness Measurement | Zhanlin Instruments Debuts at Cleanliness Technology Summit

Focus on cleanliness measurement

Zhanlin Instrument made its debut at the 8th edition

Automotive Parts Cleanliness Technology Summit

In the hot land of southern Jiangsu, Changzhou, a city that never gives up on hard work, is integrating sports spirit and industrial strength as a new force. Whether it's the passionate competition on the green field or the rising cluster of automotive parts leaders, they are converging into a powerful trend.

Although the recent performance of Changzhou in the "Su Chao" league has not been satisfactory, their perseverance of "fighting until the last minute" and remaining strong throughout the game has sparked a deep emotional response from nearly 40000 spectators and netizens across the country.

At the same time, Changzhou is making every effort to promote the development of new energy vehicles and components, with a target output value of 500 billion yuan and over a thousand large-scale enterprises by 2025. Wujin District has even surpassed a production value of 200 billion yuan, becoming a "double billion level" industrial highland in the city. Vehicle giants represented by BYD and Ideal have landed in the High tech Zone and Wujin, not only forging a strong chain effect, but also giving birth to a group of close suppliers, achieving an ecological resonance of "one enterprise leading one chain".

It is in this context that a technological event on the "cleanliness" control of automotive components is currently underway. As a key part of quality control in automobile manufacturing, cleanliness testing is shifting from being an "optional" to a "mandatory requirement".

Zhanlin Instrument, which is deeply involved in the application of cleanliness measurement, is participating in the event held in Changzhou today and tomorrowThe 8th Automotive Parts Cleanliness Control Technology Summit 2025To bring more efficient, intelligent, and environmentally friendly detection solutions to the industry. Our key promotional display plan includes——

·German SITA fluorescence surface cleanliness measuring instrument (CleanoSpector)

·German SITA dynamic surface tension tester (Science Line T100)

·Q-Lab Salt Spray Corrosion Test Chamber (Q-FOG CRH) in the United States

At the same time, we are working closely with industry experts and business representatives to explore cleanliness indicators and precision testing, as well as process optimization and intelligent cleaning.

In the current trend of increasingly precision and environmentally friendly automotive parts manufacturing, cleanliness control has become a core link in ensuring product performance and reliability.

Zhan Lin Instrument showcased a variety of professional testing equipment, includingGerman SITA surface cleanliness measuring instrument, SITA liquid dynamic surface tension meter, and American Q-Lab salt spray cyclic corrosion test chamberIt is an effective solution to meet this demand.

Principle:Based on fluorescence measurement, quickly determine whether there are trace residual pollutants (such as oil stains) on the surface.

The highlight exhibited at this summit is the well-known field of automotive cleanliness measurementGerman SITA surface cleanliness tester CleanoSpectorThe SITA surface cleanliness tester can accurately detect organic pollutants on the surface of automotive parts, including grease, lubricants, coolants, wax, and fingerprints, through the fluorescence measurement method of solitary characteristics.

Application value:

·Suitable for rapid qualification assessment of cleaned surfaces of engine casings, hydraulic components, brake systems, etc

·No need to destroy samples or use reagents, measurement results can be quantified digitally and recorded for traceability

·Can be used as a "release standard" for cleaning process terminals to avoid unqualified acceptance by the host factory

Principle: Using the maximum bubble pressure method, dynamically measure the surface tension of cleaning or coating solutions at different residence times.

Another professional equipment recommended by Zhanlin Instrument in this summit isGerman SITA Science Line t100 Liquid Dynamic Surface Tensioner.

Compared to the CleanoSpector, which directly detects the cleanliness of component surfaces, this liquid dynamic surface tension instrument focuses onPerformance evaluation of industrial liquids themselvesBy using the maximum bubble pressure method to monitor the surface tension changes of cleaning solutions, lubricants, or coating solutions in real time at different time scales, t100 can help enterprises optimize cleaning agent formulations and usage parameters, improve cleaning efficiency and consistency.

Application value:

·Evaluate the cleaning ability and adaptability of industrial cleaning agents

·Compare the performance fluctuations of cleaning solutions from different suppliers or batches, and optimize the cleaning process

·Combined with CleanoSpector, it can form a closed-loop cleanliness management plan

·Extended use: It can also be used for quality control of cutting fluids and emulsions, and is the "outpost" of cleaning/coolant management

Principle: Using controlled humidity cyclic salt spray (CRH) to simulate the corrosive environment under harsh working conditions, accelerate the testing of the performance of anti rust coatings and metal protective layers.

Although the actual machine was not exhibited, Q-LAB in the United StatesQ-Fog CRH Salt Spray Cycle Test ChamberIt has also attracted many automotive industry experts for consultation. It is used to simulate the corrosion resistance of automotive components under harsh conditions, evaluating their corrosion resistance and coating durability by exposing them to salt spray environments.

The Q-FOG circulating salt spray box can cycle between four conditions: salt spray, dry, 100% humidity (CCT type only), and static. For relatively complex automotive component testing methods, humidity or condensation can be combined with multi-step cycles accompanied by salt spray and drying.

Application value:

·Verify the stability of surface coatings (such as rust proof oil, electrophoretic layer, spray coating) on components in humid corrosive environments

·Satisfy OEM host manufacturers (such asPV1210, GMW14872, etc）Regarding the testing standards for salt spray and wet heat cycle

·Supports multiple cycle modes: salt spray+dry+humid heat, reproducing complex working conditions

·Q-FOG CRH cycle salt spray box is very suitable forChassis connectors, bolts and nuts, motor casingDevelopment and quality monitoring of corrosion protection performance for components

Cleanliness control runs through the entire quality chain, from component design and process development to on-site cleaning and final inspection. And efficient detection methods are the key to whether this chain can be "closed-loop managed".

Zhanlin Instrument always pays attention to the cutting-edge trends of cleanliness measurement technology, bringing accurate and efficient testing equipment and application support that meets international standards to the automotive industry. At the Changzhou Summit, we had in-depth exchanges with representatives from multiple host manufacturers and first tier suppliers, injecting new testing ideas and solutions for industry upgrading.

The 8th Cleanliness Technology Summit is still ongoing. If you have any questions about the application of automotive parts cleanliness testing or any related product inquiries, please feel free to consult Zhanlin Instrument at any time!
