Thermal Spray Systems

For more than 20 years, Dura-Metal has been working in the field of HVOF coating to restore worn out parts and also with OEM to develop wear resistance coating applications.

We are pleased to introduce the Durajet HV 3000 HVOF system. It’s economical, robust, lightweight, and of excellent quality. Durajet HV 3000 powder thermal spray system melts metallizing powder by heat generated through the combustion of fuel gas and oxygen. The metallizing powder is fed at a regulated speed to a flame-spraying torch that may be hand-held or motion-controlled. A continuous flow of compressed air surrounds the flame, atomizes the molten metal, and disperses it over the surface of the object to be coated. The spraying torch may be guided by hand for spraying large or intricate pieces; for production work, the torch may be mounted to programmable equipment, such as an x-y manipulator or a robotic arm. The HV 3000 system also comes with an optional add on, water cooled jacket (HV-JET HYBRID ASSEMBLY). This module will increase the torch thermal efficiency and also powder depositing efficiency – resulting in high-density coatings. This low capital HVOF equipment is an ideal system for small and medium size jobs shops.

We also offer model HV 3000-A auto-start HVOF system. It is PLC control with I/O signals or commands for turnkey integration.

The DM 3100-PS Plasma Spray System is designed and built using materials of the highest quality together with the latest technology and production methods available to deliver consistent high-quality coatings. The DM 3100-PS is also designed with safety and user-friendliness features that surpass industry expectations. It features a built-in user-operated Safety Purge System and also has the capability to run safely on Hydrogen as a secondary gas. Furthermore, all of the components in the system are designed in a way such that all electrical signals and power entering and leaving the DM 3100-PS console during purging are deactivated. This feature ensures that dangerous conditions prior to purging will be eliminated.

With a PLC and touch screen control, the user can take advantage of the many features that aid the plasma spray process. The DM 1000 power supply’s amperage is closed-loop controlled by the console, which monitors the voltage at the power supply and plasma torch. Using the DM 1200-PF powder feeders, the DM 3100-PS console commands feeders offers closed-loop RPM feeders. The DM 2000 Arc starter, a solid-state high frequency ignition unit which is powered by the console, requires no adjustment to operate. The DM 4000 heat exchanger, a 10 ton refrigerated chiller, is activated by and feeds its alarm directly to the DM 3100-PS console. The console also offers optional interface features to incorporate customer-supplied devices, such as booth ventilation switches, external E-Stop devices and manipulation control.

Highlights:
▪Touch screen control
▪ Safety purge system
▪ Automatic and manual mode
▪ Mass flow readouts
▪ Critical orifice repeatability
▪ Maintenance screens alarm
▪Series of built-in features to achieve high-quality plasma coatings

Flamejet is a compact and lightweight powder flame spraying gun for thermal spraying with powder using the oxy-fuel gas flame. Fuel gases include acetylene, propane, hydrogen in combination with oxygen as well as compressed air used for cooling purposes. Function and safety are guaranteed via a gas mixture system using the injector principle.

The Flamejet is designed for the universal application of the 2 step spray & fuse and ceramic spray coating application for wear & corrosive protection at elevated temperature.

Highlights:
▪ Integrated powder transport system
▪ With the integrated gate valve, many types of transport gases can be used
▪ Overhead position through removable and 180° changeable powder connection
▪ Just one powder connector with an adjustable slider for different capacities

Areas of use/application:
▪ Metal powder coating: for the hot and cold spraying techniques with self-fluxing or oxidized ceramic powders.
▪ Corrosion-resistant coatings: on the basis of low melting metal flame spraying powder (for example zinc and aluminum)
▪ Plastic coatings: many different types of thermo-plastics and epoxy material

VRC Metal Systems, also known as “cold spray”, is the upcoming global leader in supersonic particle deposition and other advanced manufacturing process technologies.

The majority of the world’s leading cold spray teams are using the VRC high pressure cold spray system to advance their research on obtaining the highest deposition properties and pushing the envelope on advanced recipes and hybrid coatings. The high-pressure system deposits similar and dissimilar metals on most metallic surfaces even in previously impossible heat sensitive applications. VRC’s supersonic cold spray equipment enables innovative solutions for repair, additive manufacturing and coatings for many industries including aerospace, energy, shipping, mining, and oil & gas.

Dura-Metal in partnership with VRC offers full turnkey Cold Spray system. Our mission is to provide innovative, reliable metal deposition, automation technologies and powders application know-how to give our customers market leading capabilities.

Our turnkey high-pressure cold spray systems provides coatings of the highest quality with portability that differentiates us from our competition. Furthermore, we can apply high pressures and temperatures either by robot or patented hand-held applicator. The Gen III and Raptor cold spray system is the only high pressure, portable, and hand-held capable system in the world. It is also the only high-pressure system that can reach into diameters as small as a coffee cup. VRC has played an integral part in the approval of the repair process by using our high-pressure cold spray to repair Army helicopters, Navy submarines and the B-1B Bomber in the Air Force.

Dura-Metal will partner with you in repair and restoration of aerospace, marine and industrial components including but not limited to Aluminium, Magnesium, Titanium, Niobium and Inconel.
