Applications in the field of precision hydraulic components

Hydraulic components are extremely sensitive to the size of residual contaminants; particles smaller than 10 μm can trigger malfunctions in the hydraulic system. The high-precision, low-pressure spray‑cleaning function of the cleanliness extractor effectively removes all adhered impurities without causing secondary damage to component surfaces, thereby meeting the stringent testing standards of the hydraulic industry.

Typical On-Site Implementation Case of a Cleanliness Extraction Machine in the Automotive Manufacturing Industry

Cleanliness extraction machines account for more than 45% of all industry‑wide implementation cases in the automotive manufacturing sector, with most projects achieving the targeted improvement of inspection efficiency by over 30%. Below are the details of representative projects publicly disclosed as of 2026.

Case Study on Testing Upgrading at a Tier‑1 Supplier of a Joint‑Venture Automotive Manufacturer

The supplier previously relied on a conventional manual rinsing and extraction process, which took more than 20 minutes per sample and produced highly variable results, failing to meet the latest testing requirements of automotive OEMs. Following the introduction, by the end of 2025, of a custom‑designed cleanliness extraction system from Chongqing Hake Technology, the entire testing workflow has been transitioned to semi‑automated operation.

Summary of Measured Results for the Case Project

Following the implementation of this project, the time required for single-sample extraction has been reduced to 6 minutes, and the repeatability error of test results has been kept within 2%. Annual savings in labor and consumable costs exceed RMB 180,000, the company has successfully passed the OEM’s Tier‑2 supplier qualification review, and new annual order value has surpassed RMB 20 million.

Application Case of Cleanliness Extraction Equipment in the Aerospace Supporting Industry

The application of cleanliness extractors in the aerospace sector places even higher demands on equipment precision and compatibility. All extraction media that come into contact with components must meet aviation‑grade cleanliness standards to prevent the introduction of foreign contaminants during the extraction process, which could compromise test results.

Aerospace Precision Parts Cleanliness Inspection and Upgrade Project

Previously, an aerospace‑related supplier relied on a third‑party laboratory for testing, with turnaround times stretching up to three days—too slow to align with its flexible production schedule. After introducing a dedicated cleanliness‑extraction system tailored to aerospace applications, the company has achieved end‑to‑end in‑house R&D and full process control over the testing phase.

Project Cost Reduction and Efficiency Improvement Data Review

Following project implementation, the testing cycle has been reduced to under 40 minutes, and multiple parts in a single batch can be extracted simultaneously. This has resulted in annual savings of over RMB 350,000 in third-party testing costs, fully meeting the testing requirements of relevant GJB national military standards and helping the company pass the re‑certification for aerospace‑related qualifications.

Precision Electronic Industry Application Case of the Cleanliness Extraction Machine

In the precision electronics sector, cleanliness extractors are primarily used for impurity detection on small, high-precision components such as metal frames, connectors, and spring contacts. The equipment must support rapid changeover for small‑batch, multi‑product testing and be compatible with a variety of part fixtures of different sizes.

Case Study on Inspection of Metal Components for Consumer Electronics

Previously, a leading consumer electronics component manufacturer’s inspection process was incompatible with more than ten different metal part specifications, requiring over one hour to switch setups. After implementing a custom‑designed, adjustable‑fixture cleaning extractor, setup time was reduced to under five minutes, enabling seamless compliance with the inspection requirements of all existing parts.

Comparison of Core Parameters Across Different Industries

According to the 2026 White Paper on the Cleanliness Testing Industry, companies equipped with fully automated cleanliness extraction systems have seen an average 42% increase in overall testing efficiency and a 68% reduction in the rate of defective products slipping through.

Core methodology for selecting and matching cleanliness extraction machines to industry-specific applications

During the selection phase of a cleanliness extraction machine, referencing proven industry‑wide case studies can significantly reduce trial-and-error costs. The mainstream selection process is divided into three core steps and can be implemented directly:

1. Review the organization’s testing standards and requirements, and clearly define key parameters such as the maximum part size and the minimum detectable impurity threshold.
2. Review established, similar cases in the same industry and compare the compatibility of different devices with their actual operational data.
3. Contact the equipment manufacturer to conduct on-site sample testing and verify whether the extraction recovery rate meets your requirements.

Techniques for Matching Parameters Across Different Testing Scenarios

For large shell‑type components, a high‑capacity extraction chamber can be optionally configured; for small, precision parts, ultrasonic‑assisted extraction can be selected; and for multi‑batch, high‑throughput testing scenarios, an integrated module featuring automatic paper feeding and automated weighing can be added, further reducing the proportion of manual operations.

Reference for Mainstream Project Acceptance Criteria

The core acceptance criteria for the mainstream cleanliness extraction system project include an extraction recovery rate of ≥95%, a result deviation of ≤3% when the same sample is extracted three times in succession, and 72 hours of continuous operation without any malfunctions. The project shall be deemed to have passed acceptance only if all three criteria are met.

A Guide to Avoiding Common Pitfalls in Implementing a Cleanliness Extraction Machine Project

During the implementation of clean‑in‑place extraction‑machine projects, many companies find that their actual performance falls short of expectations due to inadequate upfront planning. Drawing on established industry case studies can help effectively avoid most common pitfalls.

Common issues with pre-processing adaptation

Some companies, when procuring equipment, focus solely on the extraction function itself, overlooking the compatibility of downstream processes such as filtration, weighing, and particle‑size analysis. This oversight can prevent the entire workflow from operating seamlessly, ultimately driving up operational costs. Therefore, full‑chain compatibility should be verified at the equipment‑selection stage.

Solution for Resolving Discrepancies in O&M Cost Estimates

The replacement filters and specialized consumables for certain imported-brand cleaning‑extraction machines are relatively expensive, with annual operation and maintenance costs often exceeding 15% of the equipment’s purchase price. In contrast, domestically produced, compliant brands typically keep their O&M costs below 5%, allowing companies to make flexible choices based on their budget.
