Products as diverse as wound dressings, filter membranes, cosmetic cleansing pads and clothing labels can all be produced with a non-frayed, sealed and smooth edge using Telsonic’s Cut’n’Seal ultrasonic technology.
Cut’n’Seal uses ultrasonic energy to cut or punch out a range of thermoplastics and synthetic type materials, whilst at the same time sealing the edges and, if required, joining the individual component to a secondary item. The process can be applied to a range of substrates including very thin density synthetic melt blown or spun bond flexible materials, thicker soft materials and even injection moulded substrates.
Multi-layer substrates or laminates can also be collated and fused into one smooth edge, the company states.
The process can be extended to perform a welding operation immediately following the cutting opration. One example of this Cut’n’Weld process is the production of specialist medical consumable filters. In a fully automated operation, the filter media is fed from a reel into a machine which also presents and aligns the plastics moulded filter frames. Telsonic’s ultrasonic technology is then used to initially cut the filter membrane from the reel of material, before welding it to the moulding.
This eliminates the need for pre-cutting and collating filter membranes for subsequent presentation to a separate assembly and welding machine. The Cut’n’Weld concept can also be used in a semi-automatic configuration, if required, for lower volume products.
