Metal / plastic interface cracking
Can anyone tell me how I can avoid this?
I want to design a part using the same kind of metal - to - plastic interface as on the Krups 203-70 coffee bean grinders but I want to avoid the cracks in the corners. If it gets posted it will be: http://www.metalworking.com/dropbox/KrupsKrack.jpg http://www.metalworking.com/dropbox/KrupsKrack.txt Will this require say, a compliant adhesive gasket between my metal surface and the inside of the plastic reservoir or is this flaw primarily caused by a different problem, say a mixing issue that causes the plastic to be really brittle? Thanks! --Winston |
