Gas Cylinder Pneumatic Marking Machine
A dedicated industrial gas cylinder pneumatic marking machine featuring an 80×40 mm marking window and a 0.2–0.6 MPa air-driven impact mechanism, delivering permanent, deep (0.1–1.2 mm) indentations across curved cylinder shoulders, steel bottles, and cast parts at speeds exceeding 3 characters per second — ensuring zero consumables, high repeatability (≤0.01 mm), and complete safety in hazardous gas environments.
High-impact marks physically stamped into metal, permanently surviving shot blasting, repainting, and decades of outdoor weathering.
Powered by 0.2–0.6 MPa compressed air with no ink or ribbons; durable mechanical design built for harsh shop floors.
Repeatability ≤0.01 mm with embedded controller for auto-serializing, date coding, and inspection data without an external PC.
The Gas Cylinder Pneumatic Marking Machine is an industrial solution engineered for deep, permanent traceability on gas cylinders, seamless steel bottles, and heavy metal components. Operating on standard 0.2–0.6 MPa compressed air and AC220V 50Hz power, the system drives an ultra-hard alloy needle at 300 impacts per second, delivering marking speeds of ≥3 characters per second and permanent indentations from 0.1 to 1.2 mm deep (material dependent) across its 80×40 mm marking window.
Featuring custom curved-surface clamping fixtures, high repeatability (≤0.01 mm), and a standalone controller, it eliminates hazardous manual punch hammers with sub-8-second automated marking. With zero consumables, dust-sealed mechanics, and an explosion-proof cold pneumatic process, it ensures maximum safety, regulatory compliance, and permanent readability in gas filling stations, cylinder inspection plants, and heavy fabrication shops.

Features
Handheld Portable Design
Flexible on-site marking with a lightweight, ergonomic body. No fixed installation required, easily meeting mobile marking needs for large gas cylinders and heavy workpieces, greatly improving work efficiency.
Specially Adapted for Curved Surfaces
Clear marking without distortion. Specially optimized for cylindrical curved surfaces, firmly fitting the cylinder body without shifting. Uniform engraving depth ensures characters, serial numbers, and 2D codes remain sharp, wear-resistant, and permanent, fulfilling long-term traceability and regulatory requirements for special equipment.
Simple & Smart Operation
One-key fast marking with intuitive editing for numbers, letters, dates, serial numbers, QR codes, etc. Intuitive parameter adjustment enables quick operation without specialized training. Single-operator batch marking significantly reduces labor costs.
Stable, Durable & Reliable
Industrial-grade build featuring a heavy-duty carbide pin and rugged chassis. Resistant to oil stains and vibrations, with long service life and low failure rate. Built for demanding continuous industrial environments with minimal maintenance and low consumable costs.
