MSI’s standard Uni-forms tolerance is ± .002″ (0.05mm). For those special applications where an extremely high degree of control is required, tolerances of ± .0005″ (0.013mm) can be achieved.
Although Uni-forms epoxy preforms are available in a variety of configurations, including rectangles, ellipses, and trapezoids, the most common shapes are rings and plugs.
