Infusion 

The Cannon Epoxy infusion machines - Cannon Dx series - are compact, transportable, fully-electric dosing units equipped with closed-loop control of output and ratio. This guarantees a continuous control over the injection of these liquid resins in the vacuumised moulds that contain various layers of glass mat: the operation can last for 2-3 hours, and the flow of material varies according to the level of filling achieved.

A medium-output beginning phase is followed by a progressively reduction of flow, due to the resistance and friction created in the mould - as well as the wetting of the mass of reinforcement. The need of filling the most extreme portion of the long blades with the same proportion of resin over the reinforcement raises the problem of a continuous change of injection rate, thus the necessity of a closed-loop control of the output of both components: keeping a precise mixing ratio is a fundamental precaution to avoid emissions of non-reacted chemicals at the end of the process.

The most common models of Cannon machines for Epoxies are able to dose from 5 up to 80 kg/min of resins working in a range of mixing ratios, using a long static mixer attached to a dedicated mixing head.
