Better coatings are now possible with the new true supersonic Mach 3 HVAF gun. Generating 50% higher jet velocity as compared to second generation HVAF guns, such as SB9500 and M2, the M3’s particle velocities exceed 1000 m/sec. Higher kinetic energy of solid particles means higher contact pressures upon impact against a substrate, resulting in better adhesion and cohesion. This dramatically improves physical and mechanical properties of the coatings. For instance, hardness of WC-based coatings applied with agglomerated and sintered powder by M3 gun is increased to over 1450 HV300, which is a 30-35% improvement compared to previous generation guns.

The M3 measures and precisely controls particle temperature, eliminating all guess work from coating application, allowing exceptionally consistent coatings every time. The M3 can spray HVOF cut WC-based and Cr3C2-based powders (-45+15µm) with DE up to 75%, while also being able to accommodate fine cut powders and materials with lower melting temperatures.

HVAF Spray Gun M2

Air cooled, all-purpose multi-fuel HVAF spray gun.

Supported Fuels Propane Propylene Natural Gas (optimized for) MAPP-Gas Air 200 SCFM @ 125 PSI Particle Velocity 2000-2150 ft/sec 600-650 m/sec Deposit Efficiency Carbides 50-75% Metals 60-85% Max Hourly Spray Rate Carbides 50 lb (22.7 kg) Metals 45 lb (20.4 kg) Use Options Manual Spraying Robot Mounted

Low operating cost Highly Efficient 100% Air Cooling (no water) 100% Duty Cycle Premium coating quality Near zero oxidation of sprayed material Non-clogging nozzles Designed for spraying both cermets and metals Three nozzle configurations for carbides and metals Low consumption of spare parts Insensitive to operator error Light-weight at 4.2 lb (1.9 kg) Axial powder injection Streamlined, simple, and rugged design Instant start/stop operation

The M2 operates at Mach 2 particle velocities and efficiently sprays cermets, metals and metal alloys, including self-fluxing alloys. 100% air cooling eliminates the need for a chilled water supply. The gun's combustion chamber is optimized for operation with natural gas, which allows for dramatic cost reduction while providing good deposition efficiency. The M2 is not susceptible to nozzle clogging and can operate for hours without interruptions. The non-clogging nozzles come in several choices, the longest nozzle is used for spraying cermets, while two shorter ones are used for spraying metallic powders. Optional, smaller diameter, lower-thrust nozzles are available for manual spraying of cermets and metals. The streamlined design of the gun simplifies use with robotic systems. The powder stream is very narrow by default (resembling a laser beam), but can be adjusted by changing the powder injector to correspond to the desired spray spot.

SSTEK-P Control Console

Universal AC-HVAF Control Console

SSTEK Control System controls and monitors the AC-HVAF process, utilizing the full power of modern intelligent industrial control components. A PLC automatically sequences all functions required to start/stop the gun and accurately maintain preset operating parameters. The program shuts down the system if it becomes unable to maintain preset parameters or abnormal situations occur. A modular hardware design simplifies system maintenance. The system features an advanced touch screen user interface and user-friendly window-based screens for ease of operation and system monitoring. Designed in accordance with ATEX safety directives, the SSTEK Control System features separate gas and electrical compartments with air purging in the gas distribution cabinet.
