A line of one-piece removable tunnel gates manufactured by Exaflow GmbH in Germany is now offered here by Superior Die Set Corp., Oak Creek, Wis. The tunnel gates allow for parts to be gated in a non-visible location, providing a blemish-free part surface. Designed for small to medium-sized parts, the gates come in diameters from 0.1 to 2.4 mm, in rectangular or round cross-section, and miniflow or contoured-flow types. The gate is produced in a metal-injection molding process as a finished one-piece part that is ground on all sides. The moldmaker would machine the top and possibly front face as needed.
