The industrial design of plastic products is a complex of several professional activities. Not only the appearance of a plastic part is solved but at the same time its functional properties, technological possibilities of manufacturing, and also the economics of part and tool production.
The process of designing a plastic part is based on the client’s idea and usually begins with the production of several sketches, from which the most appropriate assignment is then selected. The chosen shape is then processed on the computer into the final form. Modeling software also allows, among other things, to simulate the final design of a plastic part, including the color, define the weight and test the mechanical properties or verify the position and functionality of moving parts.
This is followed by the production of a real model, most often in the form of 3D prints. The finished model can be viewed and tested for mechanical properties or interaction in the assembly. It is possible to make corrections and adjustments repeatedly until the final form of the part is decided. After the completion of the final form of the part, the economics of production, the preliminary price of the tool, and the plastic product itself will be specified.
The product design is completed at this stage, including verification of the economy and basic functions. The finished digital model is ready in electronic form for further processing – mold design and production.
