Magic Systems are the "state of the art" solution for quick color change.
However you can start improving the color change process in your existing line also with a smaller investment and without long installation time, just upgrading some of the key components:
The installation of the OptiGun in extended version will make the outside cleaning much quicker. In combination with horizontal in/out reciprocators and blow-off nozzles the outside guns cleaning can be automated.
You can replace your old powder hopper with a new OptiCenter. This is the real core of the color change process and will allow you to clean the injectors and hoses automatically and in very short time.
