recent formulations . Its design is derived from the famous FPL model , the L-shaped mixing head patented by Cannon in 1979 . The mixing chamber ' s geometry has been maintained , while the larger of the two hydraulically-operated plungers has been replaced by a very short piston of very narrow diameter , that leaves a tiny amount of chemicals to clean at the end of the shot in the specially designed spray tip , an operation performed with compressed air . Numerous advantages derive from this design , and from the accurate set up of the rest of the equipment that has been executed in Cannon R & D facilities in cooperation with the major Raw Material Suppliers involved in this sector of the Automotive interior ' s market :
· The distribution of chemicals occurs exploiting the kinetic energy generated by the pressure impingement system , thus it ' s totally an airless method : contrary to air-propelled application methods used by other suppliers ,
the Cannon solution provides a neat flow of pulverised formulation , totally free from mist . The final blow of air cleaning the spray tip occurs over the part itself , without generating at the end of the shift a bag of scrap foam that would need special disposal precautions . The effect on the working environment is stunning : moulds , robots , floors and the surrounding equipment stay clean much longer , there is a reduced need for fumes treatment , the working hall is in general terms more workers-friendly and a significant quantity of chemicals is saved at the end of the day .
· The spray pattern is characterised by a regular , triangular , 2D shape that , contrary to a conic pattern , distributes the chemicals precisely where they are required , avoiding any overspray between contiguous passes : this translates into a lower number of passes to cover a large mould , with much better distribution of densities , possible deposition of more material only where it is desired and an overall gain in cycle time , versus other competing methods , that can be quantified in around 20 %.
· Customers demanding a wide spectrum of output to the dispensing unit and to the head can be satisfied : the dosing machine and the LS10 mixing head can work – with the same set of injectors ! – from 30 to 300 g / s . If the design of the part to be produced allows for it , a very fast sequence of few passes , executed at high output ( or working at normal output while reducing the speed of the robot ) covers the entire surface of a luggage compartment floor for a large automobile with a part-to-part cycle as short as only 40 seconds .
· Customers using different chemical formulations ( normal or filled with mineral charges ) can do that using the same standard configuration of Cannon equipment : the whole set of parts in contact with the Polyol side is thermally hardened and treated against the abrasion .
· This simplified design of the mixing head converts into a very compact construction , with fewer hydraulic pipes , suitable for an automated application using commercial robots of medium-small sizes , that are not capital-intensive to buy and maintain .

Cannon Chinese Technicians Meet
CANNON AFROS , CANNON FAR EAST AND SHINNON HELD A JOINT THREE- D A Y T E C H N I C A L M E E T I N G I N SHANGHAI IN MARCH 2016 . THE LATEST TECHNICAL DEVELOPMENTS OF THE CANNON METERING AND MIXING TECHNOLOGIES WERE ILLUSTRATED TO 33 CHINESE ENGINEERS FROM 3 COLLEAGUES FROM CANNON AFROS .
During these three days they also discussed the most common technical problem faced in the Far East and shared with the Italian colleagues some of the latest solutions developed to solve them . This Technical Meeting , which is being held annually , is an extremely useful occasion not only to transfer the latest developments from the Manufacturing Centres to field engineers but also to create a teamwork atmosphere between the various Units that mostly keep alive the personal relationship of Cannon with its clients .
The Chinese engineers came from the Cannon Far East Offices of Singapore , Shanghai , Taiwan and from the Shinnon factory in Zhongshan . During these days ( 21 - 23 March , 2016 ) they discussed about the new technical development concerning the mixing heads ' new functions and maintenance procedures , as well as the most recent solutions for the Pentane-conversion of existing foaming plants . All the attendants had an hand-on experience as to the maintenance of the different types of mix heads .
