AMST offers powder flame spray coating equipment AMST-5P-II & AMST-6P-II for spraying ceramics and metallic powders as economical model in the powder flame spray series. Offered guns are similar to Oerlikon Metco’s Type 5P-II & 6P-II combustion powder flame spray guns. The system has light weight hand held powder flame spray gun which is unique in design and easy to operate. The AMST-5P-II & AMST-6P-II system is ideal for occasional thermal spray needs and a good choice for entry level of powder spray requirements.
AMST-5P-II & AMST-6P-II Powder flame spray system is most commonly used for the application of part restoration, wear resistance coating, non-conductive, anti-corrosion, etc . The gun has powder canister on it and thus avoids any separate requirement of powder feeder.
The gun is suitable to spray powder like self-fluxing alloys, ceramics, self-bonding material and other metallic alloys. The system offers high deposition rate of coating to meet the customer’s requirements.
AMST-5P-II Powder Flame Spray system consists of AMST-5P-II Gun, 2GFA Gas Flowmeter, gas control unit, air control unit and hose sets.

AMST offers ID extensions for powder flame spray guns for inside coating where coating flame from standard gun cannot reach. The ID extension is offered is three length 1’, 2’ & 3’.
The extension is available in 80° spray angle for coating inside any pipe like surface.
| Model | Length |
|---|---|
| Type 5PExT-1 | 300mm |
| Type 5PExT-2 | 600mm |
| Type 5PExT-3 | 900mm |
| Type 2GFA GAS FLOWMETER | |
|---|---|
| Gas Flowmeter, Type 2GFA for Fuel & Oxygen Flow rate adjustment as per parameters for each wire. The flowmeter is offered with built-in NRV for safety protection against backfire, which does not allow reverse flow of the gases. |
|
| Type 3GF GAS FLOWMETER | |
|---|---|
| Gas Flowmeter , Type 3GF with scale in NLPM & SCFH for Fuel & Oxygen Flow rate adjustment as per parameters for each wire. The flowmeter is offered with built-in NRV for safety protection against backfire, which does not allow reverse flow of the gases. |
|
| Type 3AF AIR FLOWMETER | |
|---|---|
| Air Flowmeter, Type 3AF with scale in NLPM & SCFH is a highly accurate, rugged and reliable instrument for regulating and measuring the flow of compressed air in a manual powder or wire flame spray system. |
|
| POWDER FEEDER PFD-700 | |
|---|---|
| A volumetric metering type powder feeder unit if offered to feed the gun with coating powder from feeder canister outlet. The feeder has rota-meter type flowmeter for measuring carrier gas flow readout. The powder feeder has rotating stainless steel disk with suitable number and size of the holes |

Powder flame spray process uses Fuel gas (Acetylene/Hydrogen) and Oxygen for the combustion to melt the powder in the flame to spray on the substrate, gets instantly solidifies in various layers thus gives required coating thickness of desired coating properties. Powder is fed from axially in the flame and thus uniformly melts the material to achieve required coating properties.
