To satisfy the answering of the PU market, GDE Srl has engineered a complete island for the moulding of compact or expanded material right to realize technical articles and non-skid soles device.
The island is set among the robot siliconizer and the caster. It permits to cast the device, to solidify it and be covered with expanded PU by the caster without stopping the production cycle. The island is completly indipendent: that's why it can be used with different type of machine and the very small dimensions of the mixer require a very reduced room with a high perfomance.
It's composed of:
- Isocinate tank with mixer
- Poliol tank with mixer
- Automatic loading (optional)
- Tank heating by dietermic oil
- Pipes heating for each circuit by a transformer
- Casting head and material filters heating
- From 2 to 4 tanks for paint
- Raw material and colour amount cluster composed of: three-phases induction motor with inverter, axyal reducing, material filters, volumetric amount pump, pressure switch to monitor the circuit
- Electrical panel controlled by PLC Siemens S7-300 and touch-screen panel to set: article, number, number of castings, loading, colour, mixing speed.
The mixing head is single-component created just to be able to work with a load from 5 to 30 gr/sec. It could be mounted on different devices: Manual PU Compact Island, Three axes PU Compact Island and Robot Pu compact Island.

Manual PU Compact Island
Semiautomatic machine: the operator gives the casting or pre-casting to go -ahead through a switch.
The mixing head is put on a pantographed support fastened to the mixing device; it's counterbalanced with a pneumatic cylinder kept under pressure by a regulator of precision.
It allows the operator to get closer to the "Z" axis and find the exact point for the casting in a very short time.
The support is articulated and all the remote controls are very easy to reach. Moreover, the supporter, out of use, could be refolded and blocked without hampering the workers' job around it.
