Material Jointing

Sometimes we are asked to make parts wider than available stock widths or lengths. In some cases, in an effort to meet customers’ needs, we will joint materials. Most commonly jointed materials are silicones (solids, sponges or foams). Parts are generally section cut into “sub-pieces” then jointed; an alternate method is to join the materials then cut to size (if it will fit on the cutting bed). All joints are handcrafted, thus production volumes are limited. We recommend that materials and joints be tested prior to production. Below are illustrations of two types of joints.
