We are Manufacturer, Supplier and Exporter of Dual Action Hand Spray Guns HB-35-300 and our setup is situated in Pune, Maharashtra. India. Roll & Grip® make Dual Action Hand Spray Gun® HB-35 is ideal for spraying of die coats on small forging, die-casting and rubber moulding dies. This gun is also suitable where gentle to moderately powerful spraying of die coat is needed.
Dual Action Hand Spray Gun® - HB-35
The air is needed at pressure 2.5+ Kg/cm2
for getting moderate air blast. For powerful air blast, higher air pressure may be used. For applications where air blast is not needed and where the surface to be coated is small, the air can be supplied at reduced pressure. Similarly where gentle spraying is desired, air at lower pressure is needed. Put a pressure regulator in the air supply line and reduce air pressure to the desired level. Too low air pressure would give ineffective atomisation. The die coat can be supplied using gravity feed arrangement or pressure feeding arrangement. For gravity feed, keep the die coat container at least 8 feet above the spray gun level. If using pressure feed container, the liquid pressure can be set above 0.2+ 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® HB-35 comes with different lengths of aluminium bend pipe to suit the requirement. e.g. HB-35-225 (225mm long Al. bend pipe) HB-35-450 (450mm long Al. pipe) 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.
