Custom Rotary Sealer Aline manufactures a custom semi-automated rotary sealer. Each sealer is PLC-HMI operated and is ideal for medical applications where validation is required or for industrial use. Sealers can be designed for constant heat or thermal impulse applications. The number of seal stations can be customized based on user requirements. Activation can be either with a foot pedal or dual palm buttons. Redundant safety features are incorporated into the design of each machine. A camco indexer ensures the highest degree of accuracy during the seal process.
