We are a professional manufacturer in continuous casting iron profile and its relative products. With well-equipped testing facilities and strong technical background, we adopt German patented technologies and can supply various kinds of high quality nodular/gray iron bars with different sections and sundry machine parts made of it.
Comparing to sand casting, centrifugal casting or horizontal continuous casting has many advantages, such as high density, zero deficiency , close to final shape(tube) ,reduced scrap (30%-50%), and superb wear resistance etc. So our products could be widely used in mechanical industry fields, such as hydraulic pressure, railway vehicle, oil machine, compression engine, metallurgical equipment, engineering machine, textile machine, auto engine parts, machine tool and so on.
Zhucheng Honest Industry and Trade Co., Ltd. is professional in supplying efficient products of paper making machinery , egg tray plant machinery, food washing machinery, environmental protection equipment and iron casting pipe etc and high technical service. we hope will have a good cooperation with you soon!
