Optimisation of colour change affects the entire hot runner, with special focus on the nozzle zone. The objective is to offer maximum system performance for colour change.
By means of suitable FEM analysis, followed by rigorous tests in the R&D department, the various solutions are tested. The bore channel sizing and channel finish, is designed according to the type of material to be processed. Special attention is focussed on the gate zone, which is suitably shaped for the purpose using insulation rings
- Simply and robust system;
- Efficient colour changes;
- Reduction of production waste.
