The greatest care should be used in handling to minimize the danger of the dust explosion resulting from HVOF spraying, adequate ventilation must be provided for spray booths and other confined spaces, to prevent the accumulation of fumes and dust. All types of dust having considerable calorific value can be explosive. This dust includes flour, starch, hard rubber dust, wool flour, aluminum dust and the dust of other metals. Aluminum and magnesium dusts are particularly hazardous. The dust must be wetted down and remain immersed in water. Accumulation of dry or partially wet dust should not be permitted. A GMA-SPRAY BOOTH is recommended to fulfill the requirements of the dust collection of system.
LPG VAPORIZER is attached to the system to convert the liquefied fuel into vaporized state to get the precise combustion process.
In this system the temperature can be adjusted according to the process requirements and it leads to the accurate melting of particles.
WATER JAM BOX
It has been designed to control the water flow and temperature of the cooling system,
if the temperature is exceeded to a level the system will shutdown the coating process, user can find out the temperature of the cooling water by using this system.
This is an attachment to the spray gun to provide internal coatings of the bores and mould cavities. Coating can be possible in internal diameters of 200mm. Designed to withstand high temperatures.
Produces comparative coating characteristics without compromising the actual spray coating characteristics.
Extention Nozzle are avaible for HVOF, LVOF, Powder, arcspray.
WATER COOLED JACKET
Water cooled jacket is used as an attachment to the spray gun for additional cooling of the gun when the working temperatures are too high.
For uniform flow throughout the process and uninterrupted gas supply is required. Single cylinder may not fulfill the need of the coating process.
To overcome this problem a GAS MANIFOLD is introduced to take gas from number of cylinders and sent to the gun consistently.
AJ AIR BLAST COOLING UNIT
While coating the surface of the substrate, gets heated rapidly and this leads to interrupt the process.
In order to overcome this problem GMA introduced an Air Blast Cooling Unit to propel air on to the surface of the substrate while the spraying is in-process. This prevents overheating of the substrate.
PERSONAL PROTECTIVE EQUIPMENT
GMA takes safety of thermal spray very seriously instead an option. All our HVOF systems are engineered and built for productive and safe operation.
GMA will strongly recommend the operator to follow the safety symbols which are affixed on each subsystem while operating the thermal sprays system.
GMA is following strictly the European Norms concerning equipments.
