With over a decade of expertise, CRRC QISHUYAN has been a pioneer in the cutting industry. Our machines do more than just cut; they drill holes, create countersinks, threads, and mill openings. Transform your production line with our multifunctional cutting machines that double as comprehensive production centers.
We take immense pride that our innovative ideas and ambitious visions have garnered industry-wide acclaim, positioning automated bevel cutting at the forefront of advanced manufacturing processes.
Our technology excels not only in plasma cutting but also in laser applications. Over the past five years, more than 50% of our machines have been equipped with state-of-the-art bevel cutting technologies.
Precision is crucial when producing pressure vessels, especially in the cutting of dished ends. By automatingthis process to an exceptional degree,we ensure high-precision resultswith flawless contours, eliminating the need forany additional surface finishing,thus providing manufacturerswith a significant advantage and savinga considerable amount of valuable time.
Our mission is to deliver machines that seamlessly integrate into the production workflow. By sharing information, predicting breakdowns, and automating material flow, our machines optimize the entire production cycle. Forthis reason, we are advancing ourdigital environment to unprecedented heights. Our next-generation control system epitomizes digitalization, offering tools and applications that ensure aharmonious integration into Smart Factory solutions.This seamless integration of our machinery into Smart Factory solutions highlights our commitment to advancing manufacturing efficiency and innovation.
We boast world-class manufacturing capabilities, offering comprehensive in-house processes such as casting, forging, welding, heat treatment, machining, and gearing, ensuring unmatched quality and precision.
CRRC QSYRI pioneers in casting process research and material technology development. We specialize in producing a vast array of castings, including cast steel, cast iron, nonferrous metals, high-temperature alloys, stainless steel, and cobalt-base alloys. Our advanced casting technologies, such as high-phosphorous brake shoe, Grade B, Grade B+, Grade C, and Grade E steel, have been widely adopted in the railway industry. We excel in various casting methods including low-pressure casting, centrifugal casting, metal mold casting, green sand casting, resin sand casting, pre-coated sand casting, sodium silicate sand casting, precision investment casting, and bimetal liner preparation, all enhanced with MAGMA software for solidification simulation.
We invest heavily in the R&D of precision forging, heat treatment, and product development. Our high-quality forgings, such as those for large-capacity dampers, ND5 major-minor connecting rods, 2000mm axles, brake discs, and gears, are extensively used in the railway industry. Notably, our high-temperature alloy turbine blades serve gas turbines in warships and our valve body forgings support the petroleum industry. We operate an internationally acclaimed electric screw press with a maximum pressure of 22,000 t .
We also utilize advanced technologies like Forging CAD/CAE.
Our expertise in controlled atmosphere heat treatment and precision forging covers nonferrous and ferrous metals, stainless steel, high-temperature alloys, and titanium alloys.
Our R&D extends to an array of heat treatment processes and quenching mediums, including cemented quenching, carbon-nitriding, induction quenching, and tufftriding. We lead the nation with our advanced pit-type and box-type carburizing furnace lines, and state-of-the-art quenching press and induction quenching machine lines imported from Germany. Our gear heat treatment technologies remain at the forefront, encompassing controlled atmosphere carburization, salt bath tuffnitriding, fast and deep ion nitriding, medium & high-frequency quenching, and equipment design, ensuring precise heat treatment deformation control.
We are committed to the R&D of advanced welding processes and equipment for stainless steel, aluminum alloy, and alloy steel. Our facilities feature top-notch welding and cutting equipment, including longitudinal sheet welding machines, NC air plasma cutters, Miller aluminum alloy welding machines, LVD NC sheet shearing and bending machines, and large-sized vacuum brazing furnaces. Our portfolio includes the development and manufacture of aluminum air reservoirs, water tanks, battery boxes, and water-cooled radiators.
Our dedication extends to the R&D of surface repairing and hardening technologies for large components. We employ flame-spraying, plasma spraying, and electrobrush-plating techniques. Our Miller plasma spraying system is capable of producing superior transferred coatings of metals, alloys, and ceramics.
We specialize in various advanced surface treatment methods including flame spraying, arc spraying, plasma spraying, electroplating, chemical plating, and electro brush plating. Our chemical surface treatments encompass anodizing, chemical oxidizing, passivating, phosphating, and coloring, ensuring top-notch surface integrity and performance.
