Roll & Grip® make Dual Action Hand Spray Gun® DJ-10 is ideal for spraying of die coats on forging, die casting and rubber moulding dies where simultaneous spraying of both the halves is desired. The straight pipe helps in easily spraying both the top and bottom die simultaneously. With reduced air blast provided by this gun, both the top and bottom die can be easily sprayed without much overspray where the die opening is small. The spray gun has two hose connectors for supply of air and die-coat. It has a liquid control valve for controlling quantity of die coat being sprayed. The long aluminium pipe provides easy access to all parts of die from safe working distance. This gun comes with straight aluminium pipe with nozzle at the end. The spray nozzle has two orifices on opposite faces and provide diagonally opposite spray. Since this gun provides spray on diagonally opposite sides it is very effective in spraying both the dies simultaneously without twisting the spray gun and ensures proper reach and application of die-coat with most economical hand movements.

The spray gun works in two steps. Partially pressing handle starts air and pressing the handle completely gives out spray of die coat.
The air is needed at pressure between 2 to 5 Kg/cm
2. The die coat can be supplied using gravity feed arrangement or pressure feeding arrangement. For gravity feed, keep the die coat container at least 10-12 feet above the spray gun level. If using pressure feeding arrangement the liquid pressure can be set above 0.5 Kg/cm
2. To get the effective spray and to avoid backing out of die coat, depending on the die-coat supply pressure, the supply air pressure may need to be reduced. This can be done by using air pressure regulator. This pressure adjustment is especially necessary for gravity die coat feeding since the die coat is fed at very low pressure. In addition, the liquid pressure may be adjusted along with air pressure to get proper spray.
The Dual Action Hand Spray Gun® DJ-10 comes with different lengths of aluminium straight pipe to suit the requirement. e.g. DJ-10-300, DJ-10-450 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. The aluminium pipe is interchangeable and can be changed on the shop floor in a few minutes.
Our DJ-10 model has a variant DJ-10PF which has a 14mm hexagonal nozzle. The standard DJ-10 has 25mm square nozzle. The DJ-10PF is suitable for dies with narrow & restricted opening. The DJ-10PF model requires pressure feeding arrangement for getting proper spray.
