The heart of the Tandem Technology is the locking system, the Compact Locking System (CLS).
It takes over the reliable alternating closing and opening of two parting lines within on tool. The locking is being done through hydraulic cylinders. The versions CLS 1-2 and 1-4 are also available as pneumatic versions.
The modified software for the respective injection molding machines is being regulated by limit switches. For virtually every tool size a variant of the Compact Locking Systems is available.
