The heart of Tandem Technology is the interlocking system: the Compact Locking System (CLS).
It takes over the reliable alternating closing and opening of two parting surfaces within the tool.
The interlocking mechanism is moved by a hydraulic cylinder. With the CLS1-2 and 1-4 versions pneumatic versions can also be used.
The modified software for each injection mould machine is controlled via a limit switch. A version of the Compact Locking Systems is available for nearly all tool sizes.
