Roll & Grip® make Dual Action Hand Spray Gun® MA-88 is ideal for spraying of release agent / parting agent on dies of Forging Hammers, heavy Forging Presses etc.
It provides powerful air blast for blowing away scales and cleaning the die and the spray of parting agent for quick release of component from the die.
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 hose connectors, 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 die from safe working distance. The angle of bend of the aluminium pipe ensures proper reach and application of release agent to both die halves and innermost and difficult to reach die areas.
Dual Action Hand Spray Gun® Model MA-88
The spray gun works in two steps. Partially pressing the handle releases air blast which is for cleaning the die by blowing scales and loose particles and excess die coat. Pressing the handle completely gives out spray of die coat. The spray is powerful and wide to cover the complete die with least gun movement. For spraying both the halves of the die the operator needs to just rotate the spray gun held in his hand and both halves of the die get effectively coated.
The air is needed at pressure of 6 Kg/cm
2 or more. Higher air pressure gives highly effective air blast. The die coat can be supplied using gravity feed arrangement or pressure feeding arrangement. For gravity feed keep the die coat container at least 10 feet above the spray gun level. If using pressure feeding arrangement the liquid pressure can be set above 0.5 Kg/cm
2. Whenever higher die coat quantity is needed, it is recommended to use pressure feeding arrangement. For viscous liquids higher liquid pressure may need to be set.
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® MA-88 comes with aluminium bend pipe of different lengths and with different angle of bend to suit the requirement. e.g. MA-88-300-15 (300mm long Al. pipe with 15° bend), MA-88-600-30 (600mm long Al. pipe with 30° bend) etc. The length of the aluminium pipe should be selected considering the size of machine, size of die and the distance between operator and the die. Aluminium pipe with 15� bend is most suitable for forge hammers and heavy forge presses. Aluminium pipes with different angle of bend are also available to suit the requirement.
