The Institute of Metal Physics has developed a technology for manufacturing of products with small-diameter holes (0.2-3.0 mm) and of a considerable length (up to 500 mm). To implement the process, equipment has been designed and deformation conditions have been determined to make quality products with preset dimensions. Manufacture of such products by drawing or rolling encounters great diffculties caused by the low stability of mandrels. Production of such parts by deep drilling is laborious and inefficient.

The technology ensures manufacturing of products with several small diameter holes, a three to five-fold increase in the output capacity as compared to that of deep drilling processes, and an automatic quality control of the metal used for the product under the fluid pressure deformation. The proposed technology opens up new opportunities for the development and manufacture of machine parts and instrument components, which otherwise cannot be produced or are difficult to be produced by known methods.
