The hydrostatic extrusion is a new method of extrusion process. The most important advantage of this method is reduction of friction and close tolerance for the coating thickness. In this study, the hydrostatic extrusion simulation of bimetallic wires has performed using of finite element method. In the following the advantages of hydrostatic extrusion compared to the direct extrusion are prese...

The diameter of the threaded bottom hole determines whether extrusion can proceed smoothly and fullness tooth shape after extrusion. height rate is an important indicator strength connection. In order to establish relationship between extruded internal thread, this paper takes aluminum alloy M8×1.25 mm thread as example, uses a method combining numerical simulation process test. Obtained changi...

Background: Improvement of the mechanical and tribological properties due to extrusion can be attributed to the improved density and excellent bond strength due to high compressive stress. Methods: To avoid the product defects mathematically contoured cosine profiled die was used for the thermomechanical treatment. Improvement of mechanical characterization like density, hardness, compression t...

Carbon nanotubes (CNT) are attractive next generation materials due to their unique properties, which lead to high mechanical, electrical, and thermal performance (Iijima, 1991; Endo et al., 1976; Niyogi et al., 2002; Komarov & Mirnov, 2004). This unique nano order material can not only be utilized on its own in precision industrial fields but can also provide high performance functionality in ...

We developed a 3D-printing process based on thermoset biocomposites termed Delayed Extrusion of Cold Masterbatch (DECMA). DECMA is processing method, controlling the degree curing, that takes some responsibility 3D printing from materials and as such can be used to print otherwise unprintable materials. First, masterbatch was produced by mixing bio-based resin (bioepoxy) sawdust lignin. This pa...
