This material has a relevant resistance to very low/high temperatures and to corrosive chemicals. It has good dimensional stability and it is very resistant to impacts, so it is recommended for the manufacturing of very large pieces without any need of fibre reinforcement.
Cannon technology is based on a RIM – reaction injection moulding – process, specifically designed considering additional safety issues due to the risk related to the possible formation of explosive atmosphere.
In this process two DPCD resins, the catalyst and the heat transform the liquid chemicals in a solid thermoset; the reaction takes place in a closed mould.
Cannon is able to supply the complete system: dosing unit equipped with nitrogen barrier on tanks and nitrogen blanket on drums, moulds and presses. To ease the mould internal venting, the presses could be a tilting ones and are available with a long stroke to easy the access to lower and upper parts of the mould to fix inserts. The tool change system could be customised.
The main features of our solution are:
- quick cycle time for large dimensions and high thickness
- variable thickness for large pieces
- excellent compatibility with class A finishing post mould painting
- excellent adhesion to adhesives
- increasing rigidity by moulded-in ribs or gluing of omega-shaped reinforcements
- allowing any type of fixation: over moulded inserts, self-threading inserts, rivets.
Thanks to the material’s characteristics and to the advantages of Cannon technology, DCPD processing plants are mostly dedicated to the transport sector (trucks, farming and earth moving machinery, busses) and the chemical industry.
