Flange Marking Machine

Who Need Flange Marking Machines?

Our Flange Marker Series was developed from standard pneumatic dot-pen markers because so many customers in the water, fuel, water and gas industries asked us to customize them for the connection flanges or valves. Now it has become a series of “standard” marking machines with our patented fixtures for industrial use.

Unlike other types of metal marking machines, the horizontal model machine with rotary mechanism is the basic configuration for flange and valve marking machines. We offer a range of flange markers to satisfy customers based on size and weight. Please check the specification of your flange or valve or pump and ask for the best solution.

Key Specification

Work AreaUp to 140*80mm or customize
Workpiece Dia.Up to 1000mm or customize
Workpiece Max WeightUp to 1000kg
Marking DepthUp to 2mm
Needle Duration1000 work hours

Our universal rotary flange marking machine is suitable for most flange requirements.

We understand that the number and specification of flanges in the world is astronomical and to meet the connectivity and traceability needs of all types of pipes, valves and pumps, we offer a range of purpose built horizontal and vertical flange marking machines to meet the demand.

Sufficient marking depth and consistent marking quality to ensure traceability.

We set our flange marking machines with larger amplitude and use our own production of hard marking needles, suitable for marking on a variety of hardness and curvature of the flange. The marking effect is consistently beautiful with a depth of up to 2mm, which is still visible after painting or cleaning for your demanding traceability.

Optional presets are available and can be customized to maximize your flange marking productivity.

We offer a range of easy-to-use and low-maintenance marking machines to match the specifications of the flanges you wish to mark. Whether the flange marking machine is offline or online, you can easily customize the marking content, including graphics and characters with the appropriate dimensions, and start working immediately.

This is the most efficient choice to mark huge installed flange or valve, with manual positioning to the surface and hold to mark and, you can separate information with multiple times to mark long information. We also offer customizable fixtures including magnetic models to fit snugly.

If a customer’s flange is too large and heavy to be converted to a large gantry crane, we typically provide custom tooling that allows the customer to mark the flange with a hand-held flange marking machine, achieving the customer’s marking process goals at the best price.

Experience our purpose-built markers for flange and valve marking.

As with the history of our cylinder markers, we began designing and building flange markers based on customer requests for 360º marking. The marking area for essential information is limited on the circumferential surface, and all information markings must be visible and permanent. Therefore, flange manufacturers demanded a flexible and reliable marking solution for their customers.


Precision and nimble

our flange marking machines allow you to mark thin but clear characters and graphics on your round parts;


High visible traceability

our flange markers can leave permanent marks on stiff carbon steel flanges with high visibility and fine effect;


Low life cycle cost

our reliable pneumatic flange markers consume only needles and compress air with rare failures;


Fulfillment of customization

we offer a range of customizable solutions to meet all flange, valve and pump manufacturer specifications.

Wondering how to choose the right flange marking machine for you?

Check your flange size and weight using our key specifications. If it is too large and heavy to carry on your workbench, choose a handheld flange marker and manual operation, or ask us to integrate it into a computer numerical control (CNC) gantry or robot.
