The CCM is a global solution for the production of one-piece closures and the solution acquired by PET Plastics - a CCM 48SC - is designed for the production of closures with a diameter of 26 millimetres. With a production capacity of up to 2,000 closures per minute, it has a cycle time of just 1.44 seconds. A further advantage over alternative solutions, such as injection moulding technology, is the ability to, lighter closures whose weight and parameters can be easily changed directly from the user interface.
The solution supplied to PET Plastics is also compatible with COOL+ equipped: With the innovative system for splitting the mould's cooling circuit, it is possible to achieve more uniform cooling in less time, optimise the process and increase product quality.
