KEY FEATURES

  • Specifically designed press head to limit deflection: This feature is critical when welding thin films.
  • PLC controlled: Every parameter is controlled to limit operator error.
  • Solid State 3KRF Technology: Control of RF throughout the process to limit die wear and arcing.
  • Program storage: Allows the user to easily change products without recalculating.
  • Protective guarding: Using mirrored light curtains to protect operators and still make changeover easy.
  • Data acquisition: The machine collects data from weld and process parameters to streamline future production processes.

    About Our 3KRF Rotary Welders

    Our 3KRF rotary RF welder applies a standard but effective process to every product. The first cycle is where the energy is introduced to the material and where the initial bond is formed. The second cycle applies the necessary pressure to the joint and creates the final seal.

    This double-cycle medical turntable works well with materials like polyvinyl chloride (PVC) and polyolefin (PO), often used for producing IV bags. The machines also serve similar uses involving creating an even seal around a tube. Other medical applications may include:

    • Collection bags
    • Solution feed bags
    • Blood sample pouches

    We can customize the machine based on customer requests. These adaptations allow multiple applications, creating smooth integration with existing production lines or workflows.

    Applications of This Double-Cycle Medical Turntable

    This double-cycle medical works as an IV bag sealing machine. Plastic intravenous (IV) fluid bags are used by healthcare professionals to collect bodily fluid samples from patients. These bags are equipped with tubes that allow the fluids to flow into the bag. The tubes must be sealed tightly into the bags to ensure leakage does not occur during fluid transport and after fluid collection.

    Rotary RF welding machines work well for the thin IV bag material. The radio frequency waves and double-cycle capabilities create a consistent process for sealing tubes in IV bags to prevent leaks. The machine can also accommodate up to eight sealing stations to increase production speed for this essential medical product.

    The Fundamentals of RF Sealing

    RF sealing technology relies on the generation of heat through the production of radio frequency waves, a process similar to how a microwave oven operates. In the case of RF sealing, a radio transmitter, also referred to as an RF generator, and an air-operated press work in tandem to create the seal.

    The upper die of the press is lowered against the plastic material resting on the lower die nest, producing a squeezing action that closes the path. The RF generator then creates energy that flows through the path and heats the seal area. Upon completion of the sealing action, the seal is allowed to cool under pressure. After cooling, the press opens and releases the sealed product.

    IV Bag Sealing Using Double-Cycle Radio Frequency Equipment

    In the case of medical IV bags containing tubes, a variation of the RF sealing process known as double-cycle sealing is often the most effective method. A specially designed double-cycle machine accomplishes RF sealing through two separate seal cycles.

    During the first cycle, the RF energy is applied to a mandrel (spindle) located inside the tube and between the two sheets of plastic film. The double-cycle radio frequency equipment includes two grounded semi-circle-shaped dies to ensure an even seal the whole way around the tube. During the second cycle, the press remains in the closed position. The RF is connected to the upper die while the lower die remains grounded to allow the execution of bar and perimeter sealing.

    Turntable-based systems called double-cycle TTBL machines are typically used for double-cycle RF sealing. These machines may accommodate as many as eight sealing stations to maximize productivity. Fully automated double-cycle radio frequency equipment is also available. By implementing robotics, these systems eliminate the need for operator intervention, which can significantly reduce labor costs.

    Benefits of Utilizing Double-Cycle Rotary RF Welders

    In the medical equipment production process, particularly for IVs, turntable RF welding machines provide several benefits. Here are a few of the most significant ones:

    • Productivity: Multiple stations and a turntable design allow for smooth production processes, allowing medical processes to move quickly from raw materials to finished products.
    • Quality: A specialized design with semi-circle-shaped dies creates an even seal around the tube. The double-cycle process ensures a quality seal that prevents leakage in IVs or defective final products every time.
    • Precision: The technology used by the machine allows for control of every parameter during the production process. This precise guidance limits errors from operators.
