Grob’s machinery consists of multiple stations and handles a range of process steps, including dispensing, magnet insertion, light-fixation, heat curing, shaft fitting, cooling, ball bearing fitting, balancing, as well as magnetising. Their newest systems for rotor assembly have implemented the Delolux series of curing lamps for the light fixation of Delo’s dual-curing adhesives.
According to Delo, this presents a turnkey solution that saves end users from having to cross-shop between two different suppliers.
This machinery is said to be optimised for minimal adhesive use by dispensing as little as 35 mg of product on only one side of the slot. This works in tandem with the high strength of the adhesive, enabled by a dual-curing process in which light fixation prevents the need for rotor stacks to be sealed during heat curing. The efficiency of this assembly setup continues with quick induction pre-heating, saving the rotor time in the curing oven. The machine is also compact in size, thus easily integrated into most production lines, all while still being able to process rotors up to 150 mm in diameter.
