Hot forging is a metalworking process in which metals are plastically deformed above their recrystallization temperature, allowing the material to retain its shape as it cools. In today's industry, performance of tools used during hot has always been subject interest. Although known that, tool life affects 10% design costs total budget, 80% production determined stages. For this reason, minimiz...
V-Band Clamps are manufactured using a cold roll forming process consisting of six passes which plastically deform an initially flat strip by bending to produce the band’s V-section. In this paper a new method of validating numerically predicted plastic deformation in a cold formed metal strip is presented. Tensile testing of samples of the band’s material was used to obtain a direct link betwe...
Abstract—The plastic industry plays very important role in the economy of any country. It is generally among the leading share of the economy of the country. Since metals and their alloys are very rarely available on the earth. Therefore, to produce plastic products and components, which finds application in many industrial as well as household consumer products is beneficial. Since 50% plastic...
electromagnetic forming is a high energy rate forming process in which an electromagnetic lorentz body force is used for deformation of products. in this article, electromagnetic forming process was simulated for the assembly of parts as an innovative method. the effect of important process parameters such as discharge energy, radius and width of rectangular groove on the strength of the asse...
Properties and Practical Results of Tungsten Carbide Coating Produced by Low Temperature Cvd Process
In forming tungsten carbide layer by low temperature and vacuum CVD, uniformity of film thickness, adhesion and gloss achieved when the effective zone of coating set is increased to 4450 x 1,100mm is described. Characteristics of tungsten carbide layer are evaluated and compared with other materials. Some practical applications to the mechanical parts of plastic injection molding machines are i...
Tool steels are a widely used material for construction of tools designated for shaping and forming of metal, plastic and other elements in mass production. These elements include extruding dies, pressure casting dies, moulds, punches and various other elements for plastic shaping of other materials preheated to temperatures in the range of 250-700 °C (Fig. 1). Since shape stability constitutes...
