The company has a registered capital of 360 million RMB and owns three major industries and more than 20 subsidiaries. The company has successively won numerous honors and titles, including the National Quality Award, China Famous Brand, China Well-Known Trademark, China Export Famous Brand, China Excellent Enterprise, National Key High-Tech Enterprise, National Contract-Abiding and Creditworthy Enterprise, Top 500 Chinese Machinery Industry Enterprises, and Top 100 Taxpaying Enterprises in Zhejiang Province. On December 9, 2018, Sanhua Holding Group Co., Ltd.'s "New Energy Vehicle Thermal Management System Project" won the Commendation Award of the 5th China Industrial Award. On September 1, 2019, the 2019 China Manufacturing Enterprises Top 500 list was released, and Sanhua Holding Group Co., Ltd. ranked 289th. On September 16, 2020, it was selected into the 16th list of China's Top 100 Machinery Industry Enterprises, hosted by the China Machinery Industry Federation and the China Association of Automobile Manufacturers, ranking 16th.

Yingfeiluo provides Sanhua Group with a one-stop cleanliness testing solution, including cleanliness extraction equipment, cleanliness analysis systems, and dry particle suction systems, supporting their new energy vehicle thermal management system project.

1. Cleanliness Extraction Equipment

Suitable for parts requiring overall surface spraying, local surface rinsing, overall ultrasonic cleaning, and internal cavity pressure jet cleaning, and requiring product cleanliness testing using methods such as pressure cleaning and ultrasonic cleaning. For example: cleanliness testing of engine cylinder blocks, cylinder heads, crankshafts, connecting rods, camshafts, valves, pistons, rocker arms, transmission shafts, oil pumps, water pumps, turbochargers, and other parts and assemblies.

2. Cleanliness Analysis System

>This system is a precisely designed automated optical analysis system, a new generation of intelligent cleanliness particle analysis system. It detects residual microparticles on the filter membrane, automatically identifies metal, non-metal, and fiber particles, and performs statistical analysis of the particles according to standards. It can reliably and reproducibly evaluate the cleanliness of workpieces.

> This system adopts a brand-new analysis model, redefining cleanliness particle analysis; it uses world-class hardware configuration, achieving a revolutionary leap in detection speed; the analysis process is fully automated;

> The software uses intelligent algorithms for superior image stitching, achieving more accurate particle identification, and increasing the metal particle recognition rate by 20-30%;

> Strictly adheres to international cleanliness analysis standards such as ISO16232/VDA19.1;

> This system maximizes the restoration of the original color of particulate contaminants and the accuracy of particle data measurement;

> The software is superior in performance, easy to use, and offers free lifetime upgrades;

3. Dry Particle Suction System

> The dry particle extraction system uses high-vacuum suction to collect contaminant particles. It is a new dynamic non-destructive method for particle extraction, making technical cleanliness testing of large, high-surface-area parts and on-site working environments more efficient, economical, accurate, and industry-specific, especially for lithium battery component testing.

> The equipment's suction-based collection method for contaminant particles has been tested and certified using the exponential decay method, fully complying with the relevant regulations and requirements for particle collection steps in VDA 19.1 or ISO 16232. Therefore, it meets the requirements of VDA 19.1 for reproducible comparison of subsequent microscopic analysis results.

Compared to the so-called "wet" rinsing method for particulate matter extraction (such as the liquid medium extraction method described in VDA 19.1 or ISO 16232), the dry particulate matter extraction method offers unique and irreplaceable advantages in various application fields.
