  • Minimal distortion with consistent, repeatable accuracy

Precision external tube louvering at production speed.

SANDERSON TPML4

The Sanderson TPML4 is the world’s first commercially available high-speed external tube louvering machine, delivering precise, linear louvering using components manufactured to exacting standards.

​

A key advantage of the TPML4 is its ability to louver from the inside out, eliminating internal burrs and producing a cleaner, more consistent finish. It rivals the TPM4 in speed while maintaining minimal tube distortion and high accuracy.

​

Designed for efficiency and ease of use, the TPML4 enables straightforward programming, smooth operation, and rapid tool changeovers in under five minutes — maximising productivity.

​

Each machine is built to order using high-quality components and can be customised to suit specific production requirements.
