The Company was established in Dongguan, Guangdong in 1994 mainly engaged in spray coating applications and productions.We have advanced spray welding equipment imported form Europe and America.
Thermal spraying, also known as flame spray or spray welding, which is called metalizing in the United States.Its basic principle 1s to spray the melted materials (powder or wire) onto the surface of substrates (or workpiece) through the impact ofhigh-speed gas and make the material accumulate and solidify on the surface of substrates to form a film (or coating)Through thermal spraying, we can achieve anti-corrosion, rust prevention, wear resistance, lubrication, surface roughness,adsorption, insulation and insulation and other purposes.
The use of thermal spray is quite wide. The company's business at present includes electricity industry, wire and cable industry, steel industry, cement industry, paper printing industry, shipbuilding industry, textile industry and chemical fabric industry, etc.
Thermal spraying technology types
HVOF(High Velocity Oxy-Ful Spray)Process
HVOF Spray is a thermal spraying method. It increases the pressure in the combustion chamber of the spray gun to generate a high-speed flame similar to an explosive flame. The powder material is sent to the center of the flame jet to melt or partially melt, and then high-speed continuous spraying is carried out.
Because the powder coating material impacts onto the substrate by supersonic, it can form an extremely dense and high-adhesion coating. Especially when forming wear-resistant coatings on tungsten carbide metal materials, their true value can be realized.
Wire Flame Spray
It's a spraying method that uses oxygen and acetylene flames as heat sources to melt metal alloy wires and spray them onto the surface of the processed material to form a layer. The wires used include low melting point materials such as aluminum and zinc, as well as all kinds of metal materials and alloy wires such as copper, bronze, carbon steel, stainless steel, molybdenum, etc.
Due to the fact that the processed material during the spraying process can be controlled at low temperatures, there will be no thermal effects such as dimensional changes, deformation, cracks, and strength reduction on the processed material. In addition, the thickness selection range of the spray coating is large (usually 0.1-5mm), and the particles that make up the layer are harder than the raw material, so the coating has extremely excellent wear resistance.
Spray-Fuse Process
It's a spraying method that uses oxygen and acetylene flames as heat sources to melt the powder material and spray it onto the surface of the processed object to form a coating. This method uses self-melting alloy powder as the material.
Self-melting alloy is a melting point alloy that contains boron and silicon solvents in the main components such as nickel and cobalt, with a melting point of about 1000 °C. After thermal spraying to the specified design thickness, a fusion treatment (heating and melting together with the substrate) can be used to obtain a bonding force similar to welding. During the fusion and solidification process, the coating precipitates hardened phases, thus possessing high wear resistance. In addition, it also has excellent corrosion resistance and high-temperature hardness characteristics for almost all chemical solutions.
APS(Atmospheric Plasma Spray)Process
APS is a spraying method that uses a high temperature plasma flow with an energy density of over 10000 °C to melt high melting point materials such as metals, alloys, and various ceramics and spray them onto the surface of the processed object.
The characteristic of this method is that the selection of thermal spraying materials is wide, and the bonding between the substrate and the spraying layer is strong, making it particularly suitable for spraying high melting point materials.
