Die-Cutting Matrix

Selection Logic

Selecting the right matrix depends on the board caliper and the type of fiber used in the material. A formula involving the thickness of the rule and the thickness of the board determines the optimal groove width. If the matrix is too shallow, the fold will not have enough definition to stay closed.

A matrix that is too deep might pierce the board or cause excessive stress on the machine. Operators must also consider the height of the rule to avoid crushing the surrounding board surface. Correct sizing ensures the board hinges rather than breaks.

Machine Setup

Accurate positioning is achieved using a plastic locator that snaps onto the rule before the press makes its first impression. This transfer method moves the matrix from the die to the plate in perfect registration.
