Wood powder polypropylene composites (WPC) have been produced with 40wt% of a soft or a hard wood as filler. The die drawing process developed at the University of Leeds [1] has been used to produce oriented composites. Aspect ratios (Ar) for both wood powders were calculated by using a Sysmex image analyser. Prediction of the Young’s modulus of the oriented WCP was calculated using the Cox-Kre...

In general, deep drawing products have various cross-section shapes such as cylindrical, rectangular and nonaxisymmetric shapes. The application of the surface area calculation to non-axisymmetric deep drawing process has not been published yet. In this research, a surface area calculation for non-axisymmetric deep drawing products with elliptical shape was constructed for a design of blank sha...

In conventional wire drawing the diameter of a wire or rod-like workpiece is reduced by drawing it through a conical die. Dieless drawing of a wire or a rod is realized by a localized heating of the work piece. As heat source for example an induction coil can be used. Immediately after having passed the heating zone the work piece is cooled to restrict the heat input on very small region. By ap...
