Course detail
Plastics in Mechanical Engineering
FSI-FPA Acad. year: 2025/2026 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.
