What are the differences between using in-board gasketing and on-board gasketing?
Typically, in-board gasketing is used by customers are making dedicated fixtures for long term, repeat job applications. The advantages of using an in-board gasketing in applications like these are that by recessing the gasketing (usually a 3 parts in to a 1 part above the fixture ratio), the gasketing will have an extended life time. It is only compressing to the level of the fixture, rather than fully compressing each time. The tolerance of the Z-axis will also be much tighter as there is a solid reference point to use. Also, one can program the channels to bring the gasketing to the very edge of the part, maximizing the vacuum area for the part and therefore improving holding power. However it does take some extra time to construct a dedicated spoilboard using in-board gasketing. The on-board gasketing advantages are for individuals who want to quickly set of a fizture, hold their part, and move on to the next job/program/application. The gasketing is applied directly to the surface
