Customer Cases & Successful Projects

This project features custom equipment manufactured by Qingdao Jinwo Machinery Manufacturing Co., Ltd. for China National Coal Energy Group Co., Ltd. It is a large hook-type shot blasting cleaning machine specially supporting mining machinery equipment and heavy steel structural components. Targeting the core demands of rust removal, scale elimination and surface strengthening for workpieces such as mining hydraulic supports, cylinder barrels and welded structural parts under the high-humidity and high-corrosion underground working conditions of the coal industry, the equipment addresses common industry pain points, including low efficiency of traditional manual grinding, inconsistent cleaning quality, insufficient coating adhesion, and short fatigue life of workpieces. It delivers standardized surface treatment solutions for anti-corrosion painting and performance enhancement of mining machinery equipment.

Qingdao Jinwo Machinery Manufacturing Co., Ltd. has customized a complete set of abrasive media recycling systems for the offshore engineering plant of China National Offshore Oil Corporation. Designed exclusively for coating and sandblasting workshops, the system serves the sandblasting and rust removal procedures of offshore platforms and various offshore steel structures, realizing automatic collection, screening, separation, and recycling of abrasives such as steel grit and steel shot. Integrated with pit conveying units, bucket elevators, air separators, vibrating screens, dust removal devices, and a centralized PLC control system, the complete system forms a fully closed-loop abrasive circulation circuit. It ensures continuous and stable operation of sandblasting processes while greatly cutting abrasive consumption and operation & maintenance costs. Strictly tailored to the environmental protection requirements of marine anti-corrosion construction, the equipment features fully enclosed dust control throughout the whole process, complying with the management standards for green production and compliant operation in offshore engineering plants.
