Tiivistelmä
Electrostatic charges of injection moulded test rods have been studied experimentally. Charges were generated during the injection moulding process and were measured using a Faraday pail. Several process parameters such as feeding barrel and mould temperatures, cooling time, injection speed and holding pressure were varied. Effect of these parameters on the charge were assessed using a Taguchi matrix. Electric field measurements showed that the plastic components were uniformly charged. Charge decay measurements were performed to monitor the charge dissipation. Physical dimensions were measured to ensure the usability of the products. Samples were also characterized by differential scanning calorimetry. Results prove that a significant reduction in the static charge was achieved by optimizing the process parameters using the Taguchi matrix.
