Tolerance totally depends upon sin...Dear Christian,<br />Tolerance totally depends upon sintering profile and on materials. Here in soft ferrites, granules are made up of MnZn and NiZn. While making material powder, the dimensions of granules are not even that's why tolerance range is high. Even at final sintering the temperature is not constant, which also affects tolerance.Adminhttps://www.blogger.com/profile/12743833901137477565noreply@blogger.comtag:blogger.com,1999:blog-6408332436287516652.post-79727625068920194052021-05-19T23:52:44.630-07:002021-05-19T23:52:44.630-07:00Why do both diameters and height usually have rela...Why do both diameters and height usually have relatively high tolerances? <br />(e.g. outer diameter 42+/-0.8mm ; inner diameter 26.0 +/-0.5mm ; height 18.0 +/-0.5mm)<br />Sintered steel parts reach much lower tolerances. <br />What tolerances can be achieved within reasonable cost?

It's not possible before sintering i.e. at green core stage because at sintering process the core will shrink so, your core gap length will vary.Adminhttps://www.blogger.com/profile/12743833901137477565noreply@blogger.comtag:blogger.com,1999:blog-6408332436287516652.post-61776275735767448982020-05-29T03:00:18.321-07:002020-05-29T03:00:18.321-07:00Addition;

Is that tolerance feasible by sintering process, or shall the rings be machined anyway to obtain this level of detail?Anonymoushttps://www.blogger.com/profile/18399585999998769828noreply@blogger.comtag:blogger.com,1999:blog-6408332436287516652.post-51207368865468928672020-05-29T02:56:19.777-07:002020-05-29T02:56:19.777-07:00Great article, this helps me a lot!!
For my unde...Great article, this helps me a lot!! <br /><br />For my understanding; the milling step is applied to compensate for material shrinking? I am looking to manufacture round ferrite cores with a gap (in which I can place a hall sensor to measure current). As I understand from the article the gap should be added by means of machining after the sintering process? Am I correct?<br /><br />Thanks again!Anonymoushttps://www.blogger.com/profile/18399585999998769828noreply@blogger.comtag:blogger.com,1999:blog-6408332436287516652.post-31415535311110809042019-06-11T03:12:06.500-07:002019-06-11T03:12:06.500-07:00Thanks for comment.
