Thermal spray technology

HistoryProvide spray coating service to valve ball manufacturer Since 1995.

Founded in 2009, Named as RELIS.

To satisfy market transition, our company change name to ARTECH

•ARTECH is a manufacturer who provides research, design, production, sales and service for the valve ball market.

•We have thermal spray casting solutions including HVOF, HVAF, Spray & fuse, Laser cladding, Plasma spray.

AchievementChina leader in valve ball surface technologies.

Honors•Thermal spray qualification certificate•Scientific and technological enterprise•Member of Wenzhou valve association.•Professional Committee of China thermal spray association•National high-tech enterprise•ISO 9001:2008 Certificate•Over 30 patents

Culture

• The company has most advanced thermal spray equipment:

• High Velocity Oxy-Fuel System (HVOF) ：　 JP-8000• High Velocity Air-Fuel System （ HVAF ） : AK-08• Laser clapping （ LC ） :4KW• ABB 6-axis robot ：　 IRB2600• Max capacity: 48 in 2500lbs

Coating system

HVOF

Advantages of the coating1. High performance in hardness and density.2. Control over coating density and hardness.3. Low residual stress and thickness capability up to 12.7mm.4. High interface bond strength up to 90Mpa ( Test tape invalid before coating)5. Smooth as-sprayed finish.

To satisfy the needs of high performance coating, we imported JP8000, which is one of the most sophisticated equipments, from USA Praxair. With over 60 years of coating experience, Praxair applies hardware, materials and technical expertise to HVOF products that produce the industry's most advanced coasting solutions.

JP8000 SYSTEM

HVAF

HVAF

Advantage of coating: 1. Improve toughness2. Improve corrosion resistance3. Improve tensile strength4. Improve stablity5. Improve fatigue resistance

To perfect supersonic spray technology, our company imported AK-08 equipment from USA Kermetico. It is the best one in air gun equipments in the world, which eliminates the defects of JP8000. Have JP8000 and AK08, which is ARTECH's another advantage.

Model: PJ.85Spray & fuse coating

Spray & fuse coating

Advantages of coating1.High density and low porosity2.High interface bond strength and metallurgical bonding3.High hardness up to HRC 654.Nikel or cobalt based self-fluxing alloy can be applied for 600 degrees, wear resistance , corrosion resistance shock resistance.

This process is basically the spraying of molten material onto a surface to provide a coating. Material in powder form is melted in a flame (oxy-acetylene) to form a fine spray. When the spray contacts the prepared surface of a substrate material, the fine molten droplets rapidly solidfy forming a coating which has unparalleled ultimate density and high interface bond strength.

Our company imported advanced industrial flame spray coating system from Japanese Coaken Techno, which has novel design, stable flame hard to be tempered, good sealing, free rotation and can absorb powder easily. It is very easy to spray all surface at any angle.

4KW Laser cladding

Advantage of coating ：1. Low heat input2.Quick cooling rate3.Low dilution rate4. Better coating performance

Laser cladding

Laser cladding is a new technology and a revolution for surfacing overlay. The one who masters laser cladding can have the future of surfacing overlay.

Keep Improving

Advantage ：1. Over 35 high precision NC and CNC machine.2.Execute perfect technique and follow strict complete quality control system.3.Can manufacture almost all kinds of soft seated and metal seated balls & seats, API6A gates, etc.

Machining equipment

We have high precision NC machines and CNC, execute perfect technique and follow strict complete quality control system.
