Dymet is innovative portable equipment for metal spraying.
It allows the deposition of soft metals - aluminium, zinc, copper, nickel, tin, led, babbit and titanium to any metal, ceramic or glass surface at low temperature - 120-150°C.

Technology

Dynamic metallisation technology (also known as a metal spraying) is based on the idea of kinetic bombing of substrate with metal powder particles. Due to supersonic velocity the particles bond with the treated surface on subatomic level, which guarantee high adhesion of interface and high cohesion of a homogenous coating.

Unlike thermal spray processes dynamic metallisation technology operates at almost room temperature. Cold-sprayed materials experience little or no oxidation during the process and the coatings show high densities and conductivities. This makes the technology unique.

Technology implies surface interaction of metal particles moving at extremely high velocities with the substrate. This equipment has no comparisons in traditional coating methods.

The attractiveness of dynamic metallisation method is that the equipment devices and deposited coatings have no limitations inherent in other metal coating methods and feature a number of technological, economic and environmental advantages.

Key advantages

• easy operating
• portable - can be operated in field conditions
• environmentally friendly (no gas, electric arc, ions, flame or plasma used)
• totally integrable with pneumatic and electrical control systems
• variety of applications – from decorative and protective coatings to aerospace and hi-tech
• independent from surface and atmosphere conditions

Equipment

Our small-size equipment has different technical applications mainly in assembling, repair or restoration works. The equipment can be built in automatic production lines, work posts, sections or robotic systems.
