PED-Stuart Corporation uses a combination of classic techniques which are proven to produce the highest quality results with cutting-edge technology to provide finishing which prolongs the life of the products. We specialize in radio frequency and thermal welding of polyvinyl chloride (PVC), polyurethane (PU), polyethylene (PE), and polypropylene (PP). Contact us for more information on how we can help you.

Radio Frequency Welding

Radio-frequency welding, also known as dielectric welding and high-frequency welding, is a plastic welding process that utilizes high-frequency electric fields to induce heating and melting of thermoplastic base materials.

Thermal (Heat) Sealing

Heat sealing is the process of sealing one thermoplastic to another similar thermoplastic using heat and pressure. The direct contact method of heat sealing utilizes a constantly heated die or sealing bar to apply heat to a specific contact area or path to seal or weld the thermoplastics together.


Quality Management System (QMS) complies with ISO 13485:2016 & 21 CRF 820CGMP requirements.
