Air Engraving Stylus

(Also known as Pneumatic Engraving Pen / Air Etching Tool)

An Air Engraving Stylus is a precision pneumatic marking and detailing tool used for engraving, etching, scribing, or marking on metal, glass, plastic, ceramics, and stone. It operates using compressed air to drive a fine reciprocating needle or carbide tip at very high frequency, allowing users to engrave text, serial numbers, or patterns with excellent control and consistency. This tool is essential for industrial part marking, tool identification, mold finishing, and artistic engraving applications.

Working Principle

Air Activation: Compressed air enters the stylus through an inlet valve.
Piston Vibration: The internal piston oscillates rapidly (up to 36,000 strokes per minute).
Tip Movement: The carbide or diamond stylus transfers this motion to the workpiece, producing precise engraving marks.
Adjustable Air Flow: Regulates the stroke force for deep or light engraving.

Key Features

Ultra-High Frequency Vibration: Enables smooth, fine-line engraving.
Lightweight Pen-Type Design: Provides precision and comfort for long operation.
Adjustable Power Control: For varying materials (from soft aluminum to hardened steel).
Low Noise and Air Consumption: Efficient and ergonomic.
Replaceable Tips: Carbide, diamond, or steel tips for different surface types.

Applications

Marking serial numbers or part codes on metal components.
Finishing molds or dies.
Removing burrs, weld splatter, or oxidation from fine areas.
Artistic or decorative engraving on various materials.

Flux Chipper

(Also known as Air Flux Scaler / Pneumatic Slag Chipper)

An Air Flux Chipper is a medium-duty pneumatic scaling tool designed for removing welding flux, slag, rust, and paint from metal surfaces. It uses compressed air to drive a reciprocating chisel or needle, delivering repeated impacts to chip away unwanted material efficiently. It is widely used in the welding, shipbuilding, foundry, and steel fabrication industries, where surface cleaning and preparation are required before painting or inspection.

Working Principle

Compressed Air Supply: Air pressure activates the piston inside the cylinder.
Reciprocating Impact: The piston repeatedly drives the chisel tip against the surface.
Material Removal: Each blow breaks and removes weld slag, rust, or coating layers.

Key Features

High Impact Rate: 3,000–4,000 blows per minute for quick cleaning.
Interchangeable Chisel Tips: Flat, round, or pointed tips for various applications.
Compact Design: Allows use in confined or overhead workspaces.
Durable Steel Housing: Withstands vibration and continuous operation.
Optional Low-Vibration Handle: Reduces operator fatigue during prolonged use.

Applications

Removing weld slag and spatter after welding.
Cleaning rust, scale, and old paint from steel structures.
Foundry cleaning and metal surface preparation before coating or inspection.
Commonly used in shipyards, bridges, and heavy steel fabrication.
