About Correct Design – Bosses in plastic parts
Many part designers have studied mechanical engineering and used mainly metals in their design work. The necessary differentiation by designing a metal or plastic part is therefore a lot of times unknown. However, it is truly mandatory, as the correct design of the plastic part saves material, cycle time and therefore money. A plastic part design makes the cooling of the mold easier, because less hot spots will appear. Furthermore, the first trial will be more successful, because less defects will be visible at the part, which need to be corrected.
This course describes the design of bosses in plastic parts. Bosses can be found in almost every part. They are needed to realize screw or plug connections. Therefore, it is important to understand how to design bosses in the best way. With the help of injection molding simulation, the filling behaviour of the bosses is discussed first. Different wall thicknesses will be checked and evaluated. In the packing phase, sink marks and voids are discussed, as well as the volumetric shrinkage and the molten core. At the end of the course, a compromise between the found results is made to get the best wall thickness for the bosses.
The approaches with animation and pictures are easy to understand and well comprehensible explained.

CEO at IBN-Plast
I earned more than 15 years experience with injection molding simulation, warpage as well as structural analysis during my work in my engineering office (IBN-Plast).
11 years of experience build up in quality assurance (supplier management), Audits (e.g. VDA 6.3) at Bosch Automotive and Bosch Home Appliances. Since 6 years, I have been working with different 3D printers for prototyping and near-series production at IBN-Plast.
I have 5 years of experience in manufacturing and control of technical compounds, as well as their use. I was responsible for testing of plastic granulate and its technical use, as well as processing and developing solutions of customer service complains. (CP Polymertechnik). In addition to that, I have 6 years of experience working as service manager for different IT companies.
