Technicast Continuous Cast Iron (Cci) Bars

Grey Cast Iron Bars are being produced through the continuous casting process at Technicast Engineers Ltd, Modi-nagar. Presently these Continuous Cast Iron (CCI) Bars are being produced in uniform cross sections of rounds, squares, rectangles, half rounds; in economically long lengths. These bars have excellent metallurgical superiority over the conventional sand cast iron. The casting takes place through a water cooled graphite die under metallic pressure. The withdrawal rate of the bar is controlled by a computerised machine. This advanced casting technology produces excellent, homogeneous metal with close grain structure and free from sand inclusions, blow holes, pin holes, etc. which are normally prevalent in the conventional sand casting practice. Favourable properties and economics in using CCI bars are the basis of the extensive use of this material all over the world. The fine grain structure and well dispersed graphite impart CCI bars excellent machinability. The machining speeds can be increased by 20%. The long bars are ideally suited for continuous feeding on automatic lathes to enhance the productivity of the lathe. This has also resulted in improved tool life and reduction in machining cost. The conventional castings may not be suitable for many of the applications because of non-consistence and homogeneity. In addition to these, they are prone to the usual defects of sand inclusions, blow holes, pin holes, shrinkage, etc. Because of these drawbacks, engineering industry particularly the hydraulic and pneumatic industry, often tend to specify higher grade material and therefore, costlier in goods than necessary. Due to the absence of these kind of defects in the Technicast Bars, they have become a more reliable and preferred material by many of the industries. Technicast Bars in various sections have found wide applications in the following industries: machine tool, textile machinery, hydraulic and pneumatic, glass bottle, printing machinery, and vacuum pump industry. The general engineering industry has numerous applications such as gears, bushes and pulleys, manufactured on a mass production basis. In the case of mechanical power transmission, some of the components produced are taper bushes, pulleys and gears. Generally Technicast Bars are available off the shelf in a large number of sizes starting from dia 30 up to dia 270 mm, square up to 115 mm and some sections of rectangles and half rounds.
