Pad printing machines and devices

Pad printing machines

Keller pad printing machines are designed for companies requiring a stable, repeatable, and well-controlled marking process. Each machine is built for a specific product, material, required print, and line workflow. This ensures that the customer receives not only a printing device but also a solution tailored to real-world production conditions.

Pad printing is an indirect printing technology in which ink is transferred from a matrix to the component using a silicone pad. This method is particularly effective when printing on irregularly shaped elements, convex, concave, cylindrical, or hard-to-reach surfaces. In industrial practice, however, it's important not just to understand what pad printing is, but also to ensure the machine can maintain quality, repeatability, and the intended speed.

A pad printing machine tailored to the production process

A well-designed pad printing machine should integrate seamlessly with the entire process, not just perform a single print. At Keller, we analyze the part, its feeding method, positioning, receiving, quality requirements, and operator parameters. Based on this, we select the design, control system, instrumentation, and automation level.

The device can operate as a standalone station or as part of a larger line. Depending on your needs, we design semi-automatic and automatic solutions that help reduce downtime, simplify operation, and increase production predictability. If required, the machine can be equipped with a controller, control system, workpiece transport, or additional components to support stable marking.

Pad printing machines and pad printing machines for various applications

Keller pad printers are used in industries requiring precise printing on a variety of surfaces: household appliances, automotive, medicine, pharmaceuticals, electronics, packaging, and technical components. Pad printing machines allow for the application of text, symbols, logos, functional markings, and small patterns where other printing methods are less effective.

Depending on the project, we select the pad, matrix, ink, and method of securing the part. This is important because print quality depends not only on the machine itself but also on the properly selected consumables and accessories. Accessories such as a silicone pad, inkwell, ring, or matrix directly impact the repeatability of the process.

Single-color pad printing and multi-step printing

For many applications, single-color pad printing is sufficient, particularly for technical markings, batch markings, symbols, or simple graphics. When a product requires more colors or multiple operations, the machine can be designed as a more complex system, tailored to the various workflow stages.

Keller offers models from the TampoMaster and TampoBasic series, as well as solutions developed to meet individual customer requirements. As a manufacturer of pad printing machines, we design our machines with the expected performance, ergonomics, available space, and integration into existing production.

Professional system, accessory and assistance in the marking process

Keller provides professional design, construction, commissioning, and post-implementation technical support. Our machines utilize proven, select components, including solutions from Festo, Mitsubishi, and Siemens. Remote access to devices facilitates diagnostics and a faster service response.

Our silicone pad workshop allows us to prepare pads of the correct shape and hardness. This allows us to better tailor the pad printer to the specific part, surface type, and quality requirements. We also provide assistance in selecting ink, matrix, and process settings, as well as a full range of consumables (link to the subpage).

For companies operating in the Polish market, it's not just the pad printing machines themselves that are important, but the entire implementation system: from detail analysis, through testing, to production launch. Therefore, our devices are designed to support an effective, efficient, and as user-friendly as possible marking process.
