Case show

Recently, the cleanliness inspection equipment was successfully delivered to Leikefus Spring (Changzhou) Technology Co., Ltd., completing the full service package that encompassed equipment delivery, installation and commissioning, and operator training. The equipment has now been officially put into operation, establishing a robust core safeguard for product quality control at Leikefus Spring, supporting the company’s deep engagement in the precision spring sector and enhancing its core competitiveness, while underscoring the quality-control capabilities of this foreign-invested enterprise.

Lakefors Springs (Changzhou) Technology Co., Ltd. was established in March 2005 as a wholly Swedish-owned enterprise and is part of the century-old Swedish Lakefors Group (Lesjofors AB). The company specializes in the R&D, manufacturing, and technical services of springs, innovative electromechanical components, and tooling and molds, with its products serving a wide range of high-end industries, including telecommunications, industrial applications, nuclear power, shipbuilding, defense, and automotive.

As a critical foundational component in a wide range of electromechanical equipment, automobiles, and defense products, the cleanliness of springs directly determines their elastic performance, service life, and operational safety. Residual iron filings, abrasives, dust, and other contaminants left over during manufacturing can readily lead to spring fatigue fracture, loss of elasticity, and jamming—issues that not only damage product reputation but may also result in failures of end-use equipment, warranty claims, and failure to pass customer audits. The cleanliness-testing equipment delivered this time is rigorously compliant with industry standards such as ISO 16232 and GB/T 38216, precisely tailored to meet the inspection needs for precision springs and new-generation electromechanical components that are Lekfors Springs’ core offerings. It enables the extraction, filtration, analysis, and quantitative measurement of residual particulates on spring surfaces and in crevices, allowing rapid screening for contaminants such as iron filings, sand grains, and fibers, accurate determination of cleanliness grades, and effective mitigation of contamination risks at the source—thus fully aligning with enterprises’ quality-control requirements for high-end products.

During the delivery period, our technical team maintained a full-time on-site presence, seamlessly integrating Lekfors Springs’ international manufacturing standards and precision machining requirements. We rigorously followed standardized procedures to perform equipment commissioning, installation, and debugging, ensuring stable operation, accurate test data, and compliance with international testing standards. In parallel, we conducted one-on-one operational training covering all aspects of equipment use, parameter adjustment, routine maintenance, fault diagnosis, and report generation, thereby enabling relevant personnel to master the skills required for effective equipment utilization. This ensured the efficient implementation of the testing process and its seamless integration with the enterprise’s existing quality management system.

This equipment delivery not only addresses Lakefos Springs’ capability gap in precision cleanliness inspection, thereby enhancing the company’s end-to-end quality control system from production to shipment, but also enables the company to meet the cleanliness audit requirements of international customers and high-end markets, improve product pass rates, reduce after-sales costs, and provide robust support for expanding into global markets and solidifying its position as a leading spring manufacturer in Europe.

Going forward, we will continue to provide comprehensive technical support and after-sales service, conduct regular equipment inspections, maintenance, and upgrades, and promptly respond to Lekfors Spring’s testing requirements. Together, we will deepen our expertise in precision spring quality control, leveraging state-of-the-art equipment and attentive service to help Lekfors Spring (Changzhou) Technology Co., Ltd. consistently deliver high-quality precision spring products. Backed by the century-old Group’s deep technological heritage, we will achieve high-quality development and once again set new industry benchmarks!
