After the plastic interfaces have melted, the parts are brought together to form a molecular, permanent, and often hermetic bond. A properly designed joint welded under precise process control often equals or exceeds the strength of any other part area.
In this process, the facing surfaces of the two parts are heated through conduction, convection and/or radiation from an actual heated platen. The two parts are either pressed against the hot plate, or held next to it for some period of time, then the hot plate is removed and the parts are pressed together to form the weld. Hot Plate welding typically has weld times from ten to twenty seconds. Dukane’s hot plate welders can handle parts from approximately one inch (25 mm) diameter up to five feet (1500 mm) long.

Validating your process, qualifying every part and obtaining FDA approval is easier when you partner with Dukane. Our controllable, repeatable and reliable welding equipment will help you achieve all your goals while staying cost-effective by reducing scrap.
Non-Woven
Dukane’s line of ultrasonic products offer clean, consistent and fast processing for joining and cutting nonwoven materials. From quilting mattress pads and sewing disposable health care apparels to slitting and bonding hygiene products we have designed and delivered a solution for all major film and fabric applications.
Packaging
Ultrasonic package sealing occurs when high frequency (ultrasonic) mechanical energy is transferred into two or more layers of thermoplastic materials. A strong, reliable molecular bond is formed between the layers. Nearly all packaging materials and laminates, with a thermoplastic sealing layer or coating, are suitable for the ultrasonic sealing (welding) process.
Ultrasonic Cutting
Dukane ultrasonic systems are widely used for cutting thermoplastics, textiles, films, rubber, wovens and non-wovens, and many aerospace materials. These versatile cutting systems can be operated as hand-held units or incorporated into automated solutions.
