Course detail

Plastics in Mechanical Engineering

FSI-FPA Acad. year: 2026/2027 Summer semester

Classification of plastics based on physical, mechanical, and other properties, fundamental processing methods, injection moulding, and the influence of processing parameters on the final properties of plastic products. Plastic processing machinery, manufacturability of plastic products, and mould design, especially injection moulds. Extrusion and other processes such as compression, forming, welding, and bonding of plastics. Moldflow analysis for optimizing plastic product design, mould development, and determining technological parameters.
