    Solid state technology means the ability to increase weld strength and quality while decreasing sealing cycle times. We offer an array of standard 3KRF medical  sealers with solid state technology, and we can also provide a custom design matched to your applications and requirements. Units come available with quick-change tooling to increase production and can be PLC controlled to monitor sealing throughout the entire process.

    Products featured in our inventory include:

    • Belt welding machines — Our 3KRF belt welders are capable of cutting in half the amount of time required in welding flights and cleats. From belt splicing to sidewalls, the 3KRF sealer technology increases production while reducing arcing that causes material waste.
    • 3KRF front-loading shuttle machines — We designed our solid state medical welder shuttle machines with a crystal oscillator that generates a precise power frequency. The easy loading shuttle system shortens feeding times and is adaptable for use as an automated 3KRF sealer.
    • Solid state double cycle 3KRF turntable machines — A rotary system is designed to speed manufacturing capabilities of complex medical products with improved consistency and control. The double process eliminates the need for a second unit in the production of bags with tubes sealed into them. MarkPeri offers the only 3KRF sealing machines that let you monitor exactly how much power is being applied in the sealing area throughout the welding cycle.


    3KRF technology has opened the door to innovation in the plastic sealing industry. Capable of faster precision welding that produces a stronger, longer-lasting and more attractive seal, it’s been used for manufacturing an extensive range of medical products. We’ve built hundreds of different 3KRF sealers for welding:

    • Blood bags, IV bags, urinary drainage bags and body bags
    • Blood pressure cuffs and wound evacuation pumps
    • Water mattresses, pulsating air mattresses and air inflated splints
    • Patient ID bracelets and tags
    • Environmental chambers and suites
    • Hazardous waste containment systems
    • Stretcher covers, bed covers and mobile clean rooms

    Whether you’re interested in upgrading your existing system, building a customized sealing machine or supplying your automation house with full inline sealing capabilities, MarkPeri has you covered.
