Product Description

Newly upgraded smart + high power Arc Spraying Equipment ( With PLC touch screen )

Supersonic Arc Spraying ( Supersonic Arc Spraying is a new technology developed on the basis of conventional Arc Spraying. Supersonic arc-sprayed coatings exhibit significantly superior performance compared to conventional arc-sprayed coatings and have been widely adopted in recent years across various industries, including machinery, chemical engineering, power generation, metallurgy, steel structures, shipbuilding, naval vessels, and transportation infrastructure such as ports and docks.

Supersonic arc spraying involves feeding two filamentary metallic coating materials into two conductive nozzles within an arc spray gun, with each nozzle connected to one of the two electrodes—a high-current, low-voltage terminal. When the metal filaments advance and come into contact with each other, the resulting short-circuit arc instantly generates temperatures exceeding 5,000°C, melting the ends of the filaments. These molten filaments are then atomized into fine molten droplets by a highly compressed air stream traveling at supersonic speeds—approximately twice the speed of sound. The molten droplets are propelled toward the workpiece surface at supersonic velocities (over 400 m/s) by the compressed air stream, thereby forming an arc-sprayed coating. Compared to conventional arc-sprayed coatings, supersonic arc-sprayed coatings exhibit finer coating microstructures, denser coating architectures, and significantly higher bonding strengths.

The SX-1000 supersonic arc spray gun was developed on the basis of the SX-500 arc spray gun, with an added Laval nozzle accelerating air flow chamber in its gun structure. When compressed air passes through the Laval chamber, the airflow velocity increases significantly, enabling the atomized particles to achieve supersonic spraying.

Features of the SX-1000 Supersonic Arc Spraying Machine:

The company’s latest supersonic arc spraying machine consists primarily of a main power supply, a supersonic arc spray gun, a wire-feeding mechanism, a control system, and a compressed air system. The equipment is meticulously manufactured, boasts reliable performance, and exhibits excellent operational stability, providing the most fundamental guarantee for obtaining high-quality coating layers.

1. Stable performance, easy to operate

This machine employs integrated circuits to hard-code its functions into a program. During operation, the machine automatically executes standardized procedures, thereby preventing operator errors that could damage the equipment and ensuring both operator safety and equipment reliability. The machine is also equipped with a remote control switch, allowing spray operations to be carried out even when the operator is located at a considerable distance from the main unit. The supersonic arc spraying equipment features highly stable output voltage and current, strong anti-interference capability, sensitive adjustment, uniform coating, minimal oxidation and burn-off, and can operate reliably under harsh conditions for extended periods. Moreover, the equipment boasts a long service life.

2. Wire sizes are optional, and the coating exhibits high bonding strength.

Wire diameter options: φ1.6–φ3.0 mm, suitable for a wide range of spraying applications, helping businesses save on materials and improve economic efficiency.

Coating adhesion strength can reach 70 MPa, whereas the bonding strength of conventional arc spraying typically ranges only from 30 to 40 MPa. The particles are ejected at high velocity, resulting in excellent atomization and fine particle size. Consequently, the resulting coating is smooth, highly dense (with a porosity of ≤0.5%), and exhibits significantly enhanced wear resistance and corrosion resistance.
3, The workpiece remains undeformed and its microstructure is unaffected.
The temperature rise during spraying of general workpieces shall not exceed. 100℃, so the workpiece does not deform; since the spray heat does not directly act on the workpiece surface, the spraying process will also have no impact on the workpiece’s microstructure.
4. High spraying efficiency and wide applicability.
It boasts high spraying efficiency and excellent energy utilization, capable of spraying over 40 kg of metallic wire per hour. It is ideal for on-site construction and can be used to spray a wide variety of metallic and metal-ceramic materials (both solid wires and powder-core wires), including various alloy wires, ceramics, molybdenum, aluminum, zinc, red copper, copper alloys, stainless steel, Babbitt alloy, and more. Widely used in wear- and corrosion-resistant coatings for steel structures, mechanical equipment, crankshafts, camshafts, starters, generators, fan impellers, shaft components, molds, chemical industry equipment, printing machinery, paper-drying cylinders, power generation, metallurgy, and other applications.

5, The spray gun has a large extension range, and wire feeding can be either push or pull.
The spray gun can be equipped with a 30-meter cable, an air hose, and an eight-core control cable. The spray gun’s operational radius from the main unit can reach up to 30 meters, enabling it to spray in remote job sites. This machine offers two wire-feed options: pull-feed or push-feed.
6. Wear parts do not need to be replaced frequently.
Components such as conductive nozzles are highly durable, significantly extending the service life of wear parts, reducing production costs, improving work efficiency, and effectively enhancing coating quality.

7. Easy to repair and maintain
The design of the host machine and spray gun takes into account maintenance and servicing requirements, adopting a simple-to-disassemble, compact structural approach.

Obvious advantages of imported arc spray guns:

1. The nozzle section of the imported arc spray gun consists of an air cap and a atomizing cover. The air cap comes in various diameters, and around the air cap there is a ring of air holes that generate airflow to compress the electric arc, thereby making the spray flame more concentrated. The atomizing cover can be cross-shaped, straight-shaped, or plum-blossom-shaped.

2. Depending on the different wire materials and process parameter requirements, the air cap and atomizing nozzle can be combined in various ways to produce different spray flame patterns and coating results. This can help increase the arc temperature, enhance the atomization effect, and ensure that the coating is more dense with higher bonding strength.

3. JEETR 96 The arc spraying system can be optionally equipped with... The Arc Jet kit (commonly known as the accelerated nozzle) is designed to increase the particle velocity and atomization during spraying. After installing the Arc Jet kit, the particle beam becomes more concentrated compared to that produced by a standard spray gun.

4. The deposition efficiency is 25% to 50% higher than that of a standard spray gun; particle velocity is 49% higher than that of a standard spray gun; the coating surface is smoother (reducing post-processing requirements by nearly half); porosity is lower; and coating hardness is significantly higher (more than 20% higher than that of a standard spray gun).

5. Arc Spraying Coverage rate 100%, when the ratio is in At 400 A (75% duty cycle), the coating thickness can be as low as a few micrometers.
6. The specially designed air cap ensures superior atomization. Can be sprayed handheld or machine-mounted. Suitable for spraying. 1.6 mm and 2.0 mm wire stock. Monitoring the “gun tip” pressure ensures the stability and consistency of coating quality.

7. The extremely high atomization pressure (up to 38 l/sec) makes it easier to achieve denser coatings.

8. These advantages provide users with maximum processing safety, reliability, and flexibility, including a wide range of spray coating applications and significantly improved coating quality of the arc. 9. JEETR 96 The arc spraying system of this type is currently the arc spraying system with the largest installed base in the international market.
