Uniquecoat® M2H™ Handheld HVAF Gun
Simple. Reliable. Effective.
A robust, handheld standard HVAF gun based on a single-stage combustion principle, the M2H delivers consistent performance and applies metal, alloy, and carbide coatings with reliable quality and minimal maintenance.
M2H Handheld HVAF Spray Gun
The M2H is designed for manual spraying of small surfaces and complex-shaped parts where robotic application is impractical.
It is based on single-stage combustion principle and ensures cost-efficient deposition of high-quality carbide, metal, and alloy coatings.
The system can process both standard HVAF powder fractions (5/30 um) and superfine cuts (5/15 µm, 2/10 µm) used for producing Flash Carbide coatings.
With a weight of only 3.6 kg, the M2H offers excellent balance and control during extended operation.
A built-in remote control on the handle provides quick access to jet and powder feed functions.

M2H
Typical Coating Characteristics
● WC-based coatings with hardness up to 1300 HV300
● Coating porosity typically below 0.5 %
● Compressive residual stresses in coatings improve adhesion and durability
● Negligible oxide content — only 1.5–2× higher than in the feedstock material
M2H Key Features
● Handheld or robot-mounted operation – adaptable for both manual and automated coating setups
● Cost-effective spraying – suitable for metals, alloys, and carbide materials
● Axial powder injection – provides uniform particle heating and consistent deposition
● High spray rate – delivers superior productivity and coating throughput
● 100 % air-cooled – no water chiller required
● Continuous operation – capable of spraying for hours without interruption
● Low operating cost – minimal fuel use and reduced spare-part consumption
● Fast start-up and easy operation – ready to spray within seconds for maximum uptime

Add Powder Feeder
V4™
General-Purpose Volumetric Powder Feeder
The V4 Powder Feeder is a heavy-duty volumetric unit featuring a patented blade-type feeding mechanism that ensures consistent, pulseless delivery of thermal spray powders — both metallic and ceramic. Its innovative design also prevents powder after-flow through the spray torch during shutdown, reducing waste and improving efficiency.
