Extended Head Flats Increase Dwell Time

The extended head flat is a punch modification that can improve the compression of difficult formulations by increasing the diameter of the flat area on top of the punch head. This modification offers benefits such as a longer dwell time, which can better compact poorly compressible products and potentially reduce the force needed for a specific tablet hardness. However, it may not be the ideal solution for all products. The design of the extended head flat only slightly differs from a TSM domed head or an EU head, and it can be customized to achieve a specific dwell time on a given press. Discover why consulting with knowledgeable tool vendors like Natoli Engineering to understand the role of dwell time and head flats could be the right choice for you.
