decoration in a new way,” he says.“ The idea of combining their print heads with Shibaura robots had huge potential to solve longstanding challenges in the industry.”
That meeting led to collaborative trials with TM Robotics’ Italian distributor, Tiesse Robot, and integration partner BBS robot, as well as further demonstrations at Shibaura Machine’ s Solution Fair, held at its headquarters in Japan. Those early successes gave the partners the confidence to move ahead with development. The result is a patent-pending system that integrates a heated silicone pad with a Shibaura Machine robot, for example the TVM900 6-axis.
At the core of the system is a heated silicone pad mounted on the robot. The flexible pad adapts to three-dimensional geometries, transferring pre-printed images onto surfaces that are often difficult to decorate using traditional methods. Instead of relying on inks applied on-site, the system uses reels of pre-prepared transfers supplied on protective silicon paper. These reels can be stored for up to twelve months and are loaded into the machine as needed. Decoration is achieved with controlled heat and
pressure, producing a consistent and durable finish.
Scolaro explains that this approach simplifies integration into existing processes:“ One of the key advantages is that decoration can take place directly at the moulding press,” she says.“ Instead of moving parts to a separate finishing department, we can apply the decoration as soon as the component leaves the mould. This shortens production and reduces risk of damage.”
Addressing sustainability challenges
Because it relies on pre-printed reels rather than liquid inks, the process removes the need for solvents, varnishes and catalysts.
“ This has big implications for operators,” Scolaro says.“ They don’ t need to handle chemicals or carry out lengthy cleaning cycles, which makes the whole process safer and more predictable.”
The reels are recyclable, and the decoration does not affect the recyclability of finished parts, allowing them to enter conventional recycling streams. Energy savings are also part of the picture. The heated pad doubles as both applicator and pretreatment tool— removing the need for flaming, plasma or corona discharge, all of which add complexity and cost. According to Roboprint’ s internal testing, cycle times are typically five to six seconds per part, depending on geometry and material.
Valter Scolaro adds that sustainability has been a driving factor from the outset:“ We knew that decoration had to become greener,” he says.“ By eliminating solvents and reducing energy demand, we are aligning with both regulation and customer expectations.”
Flexible applications
Flexibility is another distinguishing feature. Because the designs are preprinted onto reels, manufacturers can switch between logos, colours and patterns without halting production. Multiple decorations can also be applied to different areas of a single part in one cycle— something that is almost impossible with pad or screen printing.
