The diameter of the shaker’s armature is limited by the rating and design of the shaker. Many times, the dimensions of the test object exceeds the working area offered by an armature. In order to increase the working area of an armature, a head expander is used. We offer a varied range of head expanders to meet various testing requirement like accommodating large test articles or multiple test objects at one time. They are manufactured by welding magnesium alloy tool plates which are also used in making the coupling for Shaker to HST. They are available for any size armature with customised hole pattern as per customer requirement. Sdyn manufactures the following types of Head Expanders:   Circular Head Expander The top of the expander is circular. Any hole pattern can be provided as per customer requirement. Response is better than Square Head Expander as there are no sharp corners but the usable working area is less.   Square Head Expander The top of the expander is square. Any hole pattern can be provided as per customer requirement. Due to the four sharp corners of the square shape, the response is not as good as in the case of a Circular Head Expander but the usable working area is more. Square Head Expanders are manufactured on order basis as per customer requirement.
