Roll & Grip® make Dual Action Hand Spray Gun® RT-24 is ideal for spraying of release agent in rubber moulds, tyre moulds, PU Foam moulds etc. It provides a gentle spray, very suitable for moulds requiring fine coating of release agent. The spray gun uses compressed air for spraying the release agent. The compressed air and the release agent are supplied to the spray gun through two PU tube Push type fittings, one for air and the other for release agent. The spray gun has a liquid control valve for controlling quantity of release agent being sprayed. The long aluminium bend pipe of the spray gun provides easy access to all parts of mould from safe working distance. The angle of bend of the aluminium pipe ensures proper reach and application of release agent to innermost and difficult to reach mould parts
Dual Action Hand Spray Gun® Model RT-24
The air is needed at pressure 0.75 Kg/cm2
or more. The release agent may be supplied by gravity feeding arrangement or by pressure feeding arrangement. For gravity feed keep the die coat container at least 8 feet above the spray gun level. If using pressure feeding arrangement the liquid pressure can be set above 0.5 Kg/cm2
The atomization of die coat depends on air pressure and die coat supply pressure/quantity dispensed. Higher air pressure and lower liquid pressure/quantity gives finer atomisation and vice versa. The quantity of liquid dispensed depends on liquid supply pressure and setting of liquid control valve on the spray gun.
The Dual Action Hand Spray Gun® RT-24 comes with different lengths of aluminium bend pipe and with different angle of bend to suit the requirement. e.g. RT-24-300-70 (300mm long Al. pipe with 70° bend), RT-24-450-30 (450mm long Al. pipe with 30° bend) etc. The length and angle of bend of the aluminium pipe should be selected considering the size of machine, size of mould and the distance between operator and the die. Aluminium pipe with 70° bend is suitable for most of the applications however, different angle of bend can be provided to suit the customer requirement.
