Automated De-Pinning

Rotte De-Pinners for technical laminates, panels, and more

In the production of technical laminates, panels, multilayer materials, or coated carrier elements, pins are often indispensable for positioning, fixation, or transport. Once processing is complete, they must be removed precisely, safely, and without damage—often under time pressure and with sensitive materials. This is exactly where Rotte comes in: With specially developed de-pinning systems, we provide application-optimized solutions that make your production processes more efficient, gentle on materials, and cost-effective. Each system is individually tailored to your components and production environment.

Individually engineered de-pinning solutions for laminates and panels

Whether thermoset or thermoplastic laminates, carrier panels, or fiber-reinforced composites—our de-pinners are precisely adapted to your material properties, production cycles, and takt times. At Rotte, our team develops both compact standalone units and integrable de-pinning modules for existing production systems. We take into account all requirements for throughput, part handling, and process reliability—always with the goal of ensuring maximum efficiency with minimal material wear.

Expertise for your de-pinning processes—with Rotte at your side

Our de-pinners are used in a wide variety of applications: in laminate processing for removing fixation pins after pressing, in the production of aluminum or steel panels as a removal step after pre-positioning, in electronics manufacturing for multilayer PCBs, or in the furniture industry for de-pinning veneered carrier materials. Wherever flat materials need to be processed pin-free after precise machining for further production or packaging, Rotte’s customized de-pinning systems are the solution of choice.

Your benefits:

Safe removal of pins without affecting the panel surface
Gentle force application to the carrier material through finely tuned systems
High repeat accuracy for consistent quality in series production
Flexible adaptation to different formats, material thicknesses, and pin positions
Increased efficiency by eliminating manual de-pinning and reducing scrap rates

Technology for processing the most demanding materials

For handling sensitive or multilayer materials, our de-pinners use servo-electric or pneumatic drive technology with precisely controlled force application. Intelligent sensors monitor the exact position and depth of the pins, while specially designed tools ensure safe and material-friendly removal. This makes it possible to process fragile or coated surfaces without pressure marks, deformation, or delamination.

Seamless integration into your production line

Rotte de-pinners can be perfectly integrated into existing manufacturing processes. Whether inline between milling and cleaning, as preparation before further processing, or as part of a quality assurance step—our systems communicate via standardized interfaces and can be combined with conveyors, robots, or workpiece carriers. This enables continuous, automated process chains for maximum productivity.
