Coating Removal System

Ultra-High Pressure Waterjet Coating Removal is an environmentally friendly process that uses the kinetic energy of ultra-high pressure water jets to remove thermal spray coatings. This technology is highly efficient, has no thermal impact, and does not damage the substrate. It is widely used in aerospace, semiconductors, LCD panels, medical devices, new energy equipment maintenance and other fields. It has become a key process in the field of thermal spray coating repair and remanufacturing.

Rotating Jet Mode

The externally driven jet modeutilizes a high-pressure water jet nozzle driven by a servo motor, capable of reaching a maximum working pressure of 4,000 bar. Its rotational speed is adjustable steplessly from 0 to 1500 rpm.

Single-Orifice Jet Mode

The single-orifice jet modeconcentrates energy more effectively and delivers significantly greater impact force on the target object compared to multi-orifice jet modes. It is primarily used for applications involving hard surfaces and clogged obstructions.

Fan-shaped Jet Mode

The fan-shaped jet mode disperses the water stream into a flat, fan-like plane, offering a significantly wider coverage area compared to the single-orifice jet mode. It achieves much higher efficiency when cleaning larger surfaces or planar structures with regular shapes.

Customized Jet Mode

The customized jet mode is a specially tailored jet solution developed by Fedjetting. It is designed based on comprehensive simulation analysis of the customer's actual application scenarios and the specific force requirements for the workpiece surface material.

Ultrahigh-Pressure Waterjet Technology

UHP waterjet technology is an extremely versatile process. Cut or trim virtually any material, nearly any geometry, and with precise tolerances. Whether you’re cutting turbine blades, blisks, composites structures, or other complex parts, removing ceramic shell from cast aerospace alloys or removing coatings as part of engine repair activities our ultrahigh-pressure waterjet solutions are a preferred processing method for industry leading organizations.

Process Principle

Kinetic Stripping

Using an ultra-high-pressure pump (typically in the 1000-4000 bar) to pressurize water, the water jet is formed into a high-speed jet (up to 800-1000 m/s) through a specialized nozzle. The kinetic energy of the water jet impacts the coating surface, breaking the bond between the coating and the substrate, thus achieving coating stripping.

No Chemical Pollution

Using only pure water, no chemical solvents are required, resulting in excellent environmental protection.

Cold Working Properties

The water jet removal process does not generate high temperatures, preventing thermal stress that could cause deformation or performance degradation of the substrate.

Water Jet Solution

Waterjet Coating Removal for Aero Engines Components & IGT

Fedjetting’s ultrahigh-pressure waterjet stripping (WJS) solutions remove tough coatings on aero-engine and IGT components with ease. With a shearing force higher than the strength limit of the material, soft and hard deposits like thermal barriers, wear-resistance, or corrosion-protection, and resins, adhesives, rubbers and more, are removed efficiently, safely, and cost-effectively.
