For Precisely Coated Interior Geometries: preeflow Introduces eco-SPIN Dispensing Solution

29.10.2025
Whether adhesive, lubricant, grease, silicone, polyester, or epoxy resin – applying media accurately and precisely inside an interior geometry is a technically demanding task. To enable industrial manufacturers to achieve precisely this with maximum efficiency and precision in cavities, internal threads, or shaft-hub connections, for example, preeflow has added the eco-SPIN to its portfolio.

In combination with the eco-CONTROL EC200 2.0 dosing control system, the dispenser with the rotating applicator provides a complete solution for the user.

This innovative dispensing and application technology ensures uniform coating within complex components, allowing them to be bonded, sealed, or protected from external influences. The eco-SPIN has no viscosity limitations: thanks to its rotating spin head, it can apply both low- and medium-viscosity media. The sophisticated technology, an adapted control system and the principle of the rotating centrifugal disk form the foundation of a highly reliable and efficient manufacturing process – ensuring top-tier component quality while minimizing material waste. This makes the eco-SPIN the preferred technology for industries where the quality of interior geometries is just as critical as external surfaces, such as the automotive, aerospace, and electronics industries.

Key Features of the eco-SPIN:

  • Precise media distribution and uniform application, even in complex cavities or deep bores
  • Proven and controlled spray technology, ensuring high efficiency while reducing material consumption
  • Compatible with a wide range of media, accommodating various viscosities
  • Maximum process reliability and consistent high quality through reproducible parameters
  • Parameterization, control, and monitoring via the eco-CONTROL EC200 2.0 control unit
  • Can flexibly be customized to meet specific customer requirements

"With the eco-SPIN, we offer an innovative solution for companies looking to automate and optimize adhesive processes," explains Thomas Hochholzer, Technical Sales & Product Management C&D – just one of many possible applications. He adds: "Our technology ensures not only precise dosing but also a significant increase in production efficiency."
