This vertical rotating dot pin marking machine is a flagship model of the Dot Peen Marking Machine, specifically designed for the shoulders of small to medium-sized steel cylinders (5–50 L, 40–650 mm in length, 10–250 mm in diameter, and 0.1–50 kg). It integrates the powerful impact of a pneumatic marking machine with the micron-level positioning philosophy of a laser marking machine into a single servo-rotating architecture: long-amplitude tungsten carbide needles maintain zero distortion of the lettering even on curved surfaces, with a single impact depth of 0.3–0.5 mm. Whether marking precedes painting or vice versa, it leaves permanent, traceable markings that meet stringent standards such as DOT, ISO, GB, and TÜV.
For medium-sized industrial gas suppliers with daily throughput often reaching thousands of cylinders, this marking machine is equivalent to implanting a lifelong readable "digital ID card" into the cylinder at its "birth," providing error-free data anchors for subsequent filling, inspection, logistics, and even recalls.
The entire machine adopts a vertical layout, simplifying the traditional horizontal system's "push-roll-lift" three-step loading process to a "one-hook and fix" method—reducing manual loading labor by 55%. It can also seamlessly connect to forklifts, overhead cranes, hydraulic power arms, or six-axis robots, enabling a flexible transition from a single-shift three-person operation to an unmanned, lights-out factory. The wall-mounted Thorx-6 touchscreen controller is separated from the main unit via an aviation quick-connect cable, with a customizable 30-meter cable, allowing engineers to perform multi-machine collaboration, pattern switching, and remote diagnostics from an air-conditioned room. The enclosed Pneumatic marking machine power module shares the same 24 VDC safety circuit with the low-power Laser Marking Machine positioning system, reducing power consumption by 18%, noise level to <68 dB, and extending the maintenance cycle from 500 hours to 2000 hours. A simple 5-second quick-release filter and one-button self-lubrication ensure that the tungsten steel needles of the Dot Peen Marking Machine maintain micron-level sharpness even after millions of impacts.
Whether it's the JIT cycle on the filling line or the storage and transportation base in the high salt spray of the seaside or the extreme cold of -30°C inland, this vertical cylinder rotating dot pin marking machine, which integrates three major technical routes, can complete a deep, clear, and non-fading "zero-defect" mark in 52 seconds, writing a reliable promise for each cylinder across its 20-year life cycle.
