During injection molding of highly filled polymers it is necessary to avoid any inhomogeneities arising from high shear rates/stresses created in molded parts, because they lead to uneven shrinkage after molding, dimensional instabilities and even cracks and voids in the final parts. The testing mold design to intercept so called powder-binder separation has been upgraded to a 3D cube-like model and constructed. Investigation of a tendency to phase separation is however strongly affected by a material and a surface structure of a processing tool. Therefore, flowability of various filled materials in the flow channels designed from different construction materials were tested and compared within this contribution.

Controlling the heat during cutting operations are an important factor in improving the quality of the product and performance of the machining. For controlling the heat, there are a lot of methods. One of this is Vortex Tube Cooling System. In this study, the Vortex tube cooling system was used to control heat during the turning operation. In the design of experiment, cutting speed, cooling temperature, feed rate, and cutting tool corner radius were selected as input parameters. Surface roughness and cutting force was selected as output parameters. The input and output parameters were modeled by using Artificial Neural Network, the results of experiment were optimized.
