Prediction of residual stresses in injection moulded parts
For automotive plastic parts, mostly used for interior assemblies, there is a clear demand of an increased accuracy of the simulation model. One crucial input for the simulation model is the correct material data. Based on test data, it is known that the dynamic material properties of a plastic part can differ significantly from the material data given in the data sheet (which is based on a spe...
متن کاملStudy on residual stresses of thin-walled injection molding
The residual stresses of the thin-walled injection molding are investigated in this study. It was realized that the behavior of residual stresses in injection molding parts was affected by different process conditions such as melt temperature, mold temperature, packing pressure and filling time. The layer removal method was used to measure the residual stresses at a thin-walled test sample by a...
متن کاملLCA as eco-design tool to support the development of injection moulded products
The use of recycled materials reduces the need for primary materials and it also minimizes the amount of waste in the production process. Therefore, by using recycled materials, the total material flow necessary for the production of a product can be reduced. Moreover, the total consumption of resources for the production of recycled material is, usually, remarkably inferior that in the product...
متن کاملCALCULATION OF RESIDUAL VOLUME BY SPIROMETRIC DATA
ABSTRACT Background: The current practice to measure RV is either by BPG or helium dilution methods which may not be available in all clinics due to their cost. Methods: This paper outlines a method for both direct and indirect calculation of RV via PFT with acceptable sensitivity (81 %, 60% ), specificity (71 %, 94%) and validity (76%, 78%) for obstructive and restrictive lung disease respect...
متن کاملMiniaturised free flow isotachophoresis of bacteria using an injection moulded separation device.
A new design of miniaturised free flow electrophoresis device has been produced. The design contains a separation chamber that is 45 mm long by 31.7 mm wide with a depth of 50 μm and has nine inlet and nine outlet holes to allow for fraction collection. The devices were formed of polystyrene with carbon fibre loaded polystyrene drive electrodes and produced using injection moulding. This means ...
