Method for cutting through a hollow profile pressed into a mould by internal pressure with two shaped plates with a cutting groove with support inserts

摘要

A method for clean cutting/trimming of a hollow profile produced by pressing into a mould via internal pressure has two shaped plates (1) clamped around the cutting site and presenting a cutting groove (5) filled with support profiles (7) which have sufficient freedom to support the cutting process without any tear damage to the cut edge. The cutting/trimming is via the applied internal pressure at the end of the moulding process.
