<abstract xmlns="http://www.w3.org/1999/xhtml">The present paper is an experimental study on the squeeze pin effect on the high pressure die cast aluminium parts, as a way of improvement of material homogenity on various and big wall thickness castings. Squeeze is used in high pressure die casting technology for optimizing homogenity of big wall thicknesses of die cast parts working as structural, mechanical and hydraulic components, made of different aluminium alloys such AlSi alloys. The objective of this research is to highlight the primary and secondary effects of squeezing on the structural homogenity of high pressure die cast aluminium parts, as well as the dependence of the effects on the squeeze pin dimensions and the operating parameters.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The elastic couplings are frequently used in mechanical transmissions design, to take over the radial, axial and angular misalignments and also to take over the shocks and the overloads that could appear. In this paper is presenting some aspects about the construction of couplings with bolts using non-metallic elements, e.g. rubber, having different hardness, the elements involved in torque transmission, in this case elastic elements, having also different dimensions or forms, in the way to have a good elasticity and capacity of vibration absorbtion, determining theoretical static rigidity and experimental static rigidity of a new elastic coupling with cylindrical bolts and nonmetallic elements and compare of results for these values.</abstract>
