Serac’s new rotary, servo-driven capper, the eMC2, is gaining traction in the home care products industry due to its ability to handle nearly all closing systems, including caps, pumps, and trigger sprayers, with quick changeover and high accuracy.
At PACK EXPO Las Vegas, Serac Managing Director Nicolas Ricard explained the benefits of the brushless servo motor-driven eMC2. “With fully electric cappers, the rotation as well as the up and down movement are controlled by a motor,” he says. “This allows us to do a simple cap, or a pump, or a trigger on the same capper with limited changeover. With all functionalities being recipe-driven, the eMC2 enables operators to easily control the position of the capping head, ensuring consistent results.”
A primary concern for brand owners is the traceability of their products. Traditional cappers, if they malfunction or don’t cap correctly, often require additional inspection processes to identify issues. In contrast, the eMC2 enables proactive identification of potential capping errors. By setting specific targets for the capping process within the machine, operators can ensure that if the desired number of turns or the correct torque is not achieved, the bottle is rejected, reducing the chances of sub-optimal products reaching consumers. Moreover, the data-driven approach means manufacturers can maintain detailed records of each capping process, allowing for efficient troubleshooting in case of post-production challenges.
As Ricard explained, the transition to electric cappers isn’t solely driven by their operational benefits. Many companies have also begun to recognize the value of minimizing manual interventions, especially where consistency and hygiene are paramount. Manually attaching certain components, like trigger sprays, poses risks such as introducing contaminants or not achieving the desired precision in the capping process. The eMC2 mitigates these risks, assuring products maintain their intended quality.
Serac provides specially designed capping heads for the eMC2 that can be changed easily to adapt to plug-on sprays, lotion pumps, dispensers, caps, and other closing solutions. The system runs at speeds to 400 triggers/min and 560 standard caps/min, with 16 capping heads and can be operated as a standalone unit or in a monobloc filling/capping system. PW
