undercut Explanation: I'm not a technician that I would be able to explain it technically. However, as I am working in the plastics industry where this term is often used I am sure that this term is the right one. I had a technician once explain it to me. |

Draft angles for ejection MIM green parts exhibit less strength and less shrinkage than usual polymers. Thus they need large size ejectors and large draft angles. Draft angle > 1° Ejectors: 4-6 times larger compared to plastic injection moulding -------------------------------- the process is also called "demoulding" - see the KudoZ link above. Therefore, one can also find "demoulding (draft) angle" - see links below, but way less internet hits and not US or UK: examples: http://www.4m-net.org/node/2170 Abstract Demoulding micro structured surfaces and micro parts is an important issue in replication of micro technology based components. In this paper a state of the art on ways to improve demoulding of microstructured parts both in polymer moudling and metal injection moulding is presented. The approach is described and simulation methods are shown in relation to previously existing studies. The approach chosen is the investigation of the influence of the demoulding angle on the demouldability of polymer mouldings. http://www.mess-regeltechnik.at/LICO/Grilamed_prospekt_4007_... mold release draft angle/draft angle Grilamid TR gives a very accurate reproduction of the mould surface. In order to obtain moulded parts with glossy surfaces the mould surfaces must be finely polished. Rough surfaces may cause problems with mould release. Structured surfaces require a mould release draft angle corresponding to the depth of the structuring. |
