11 Months of Reliable Protection: GIS Earns Customer Trust with Quality and Service

Recently, Jiangxi GIS Engineering Technology Co., Ltd. (hereinafter referred to as “GIS”), a subsidiary of Nanchang Mineral Systems (NMS), once again won high praise from customers for its outstanding product quality and professional after-sales service.

At the production site of a large iron ore project in Sichuan Province, a set of liners supplied by GIS was installed on a gyratory crusher from a well-known international brand. After 11 months of continuous operation, the liners remained in serviceable condition, demonstrating excellent durability. When the scheduled maintenance cycle arrived, the client proactively requested a liner replacement. The GIS service team responded immediately and efficiently completed the replacement of both liners and other spare parts, ensuring the stable operation of the client’s production line.

These liner products were specially developed by GIS to withstand the harsh working conditions of mining operations. Through the adoption of innovative material formulas and precision manufacturing, the liners demonstrated industry-leading wear resistance, impact strength, and extended service life. According to client feedback, under a consistent throughput of 2,400–2,600 tons per hour, the liners performed stably throughout the 11-month operation period. Compared with the previously used high manganese steel liners, the GIS liners achieved a 10% to 37.5% increase in service life, significantly reducing downtime and maintenance costs—providing strong support for efficient production. These results not only highlight GIS’s R&D capabilities, but also reflect its customer-centric design philosophy.

In addition to the mantles and concaves, GIS also supplied other key spare parts for the crusher, including the spider bushing, main shaft sleeve, and eccentric bushing. While ensuring high-quality domestic replacement parts, GIS also demonstrated its robust technical service capabilities. Previously, the company had helped the client upgrade the crusher’s protection and control systems. The next step will be to assist in chamber optimization, with the goal of increasing throughput and enhancing economic returns.

Once the client requested the replacement, the GIS team activated its rapid response mechanism. Equipped with professional tools, engineers were quickly dispatched to the site. Upon arrival, they immediately assessed the wear condition of the removed liners and other components, while also conducting a comprehensive inspection of the crusher’s operating status. Once the new parts arrived on site, GIS service engineers provided on-site technical guidance to ensure correct installation and successful commissioning. The entire service process was efficient and well-coordinated, minimizing downtime. The equipment maintenance cycle was significantly reduced from the original 20 days to just 15 days. During the visit, GIS engineers also offered optimization advice and conducted on-site training for project technicians, enhancing the client’s maintenance capabilities.

A project representative commented: “We trust GIS for the quality of their products, but we’re even more impressed by their service. From pre-sales technical support to post-sales maintenance, every step was professional and thorough. The 11-month performance of the liners exceeded our expectations, and the fast, efficient replacement process showed GIS’s true commitment to customer satisfaction.”

This case is a vivid demonstration of GIS’s commitment to high-end quality and professional service. As a core subsidiary of a leading mining equipment manufacturer, GIS always prioritizes customer needs. Through a global service network, 24/7 emergency response, and customized spare parts programs, GIS has helped NMS build a full-lifecycle service system, covering everything from product delivery to after-market support.

Looking ahead, GIS will continue to drive innovation, focus on customer-centric solutions, and expand its integrated product-service offerings, helping clients reduce costs, increase efficiency, and achieve sustainable development. GIS is committed to supporting the global mining industry’s journey toward high-quality growth.
