At the heart of the system is a smart rotating wheel, equipped with six independently controlled arms. Each arm gently holds the stator from the outside, keeping the internal components clean while allowing it to spin for an even and accurate application of resin. This external gripping method not only ensures a neat process but also dramatically cuts down on cleaning and maintenance time.
One of the machine’s most innovative features is its use of induction heating, which eliminates the need for traditional convection ovens. This approach greatly reduces preheating time and contributes to the machine’s compact design, allowing it to operate within a much smaller footprint. The system is also capable of automatic parcel adjustment, providing flexibility for different stator sizes and production requirements.
A key feature of the machine is its modular vertical wheel system, designed to adapt precisely to the customer's specific process requirements. The current standard configuration includes seven positions, defined according to process times and the customer's cycle time: one position for loading/unloading, one for preheating, one for resin trickling, two for gelling, and two for curing. However, the wheel can be configured differently — for example, by adding a second trickling station when processing longer stators that require extended impregnation time. This flexible design approach allows for process optimization based on the stator size, total cycle time, and the type of resin used, ensuring maximum efficiency and high-quality results.
Key benefits at a glance:
All-in-one solution: From heating to curing, all steps happen within one compact unit
Space-saving design: Its vertical layout makes it ideal for modern, efficient production spaces
No ovens needed: Induction heating brings quicker results and lower energy use
Fast and ready: Fewer moving parts mean the machine is ready to work almost immediately after start-up
In short, GROB’s impregnation machine combines smart engineering with practical advantages, helping manufacturers achieve more with less—less space, less time, less energy. It’s not just a machine; it’s a smarter way forward.
