TOSS Machine Components, Inc., a manufacturer and distributor of impulse heat sealing components and supplies, targets packaging processes with its advanced seal and cut heat seal bands. Designed to address the specific needs of sealing battery cells and packs, TOSS seal and cut bands offer precision, efficiency, and customization.
Three key offerings—Beaded Bands, T-Profile Bands, and Custom Seal-Cut (CSC) Bands—stand out for their ability to deliver consistent, reliable seals while cutting polymeric films in a single process. Each band incorporates unique design features and technology tailored to various applications.
The Beaded Band design includes tapered edges, eliminating sharp and high-temperature outer edges for safer handling and consistent performance. The bead itself retains more heat than adjacent edges, enabling precise cutting without overheating the sealed areas. Additionally, the space behind the bead is designed to avoid contact with the underlayment backing material, preventing heat loss and ensuring efficient operation. This band is ideal for high-cycle processes where reduced material waste is paramount and dependable seals ensure product integrity.
The T-Profile Band provides a greater mass per unit length and therefore is able to retain more heat, making it effective for cutting through thicker film stacks or multi-layered films. Featuring a sharp cutting edge and a relieved back design, this band minimizes contact with underlayment backing, ensuring efficient heat distribution. The T-Profile Band’s ability to cut and seal simultaneously makes it particularly suited for packaging applications in the battery and electric vehicle (EV) industries, where durable seals and high cycle rates are essential. Furthermore, depending on shape and application, the T-Profile band can be curved to make contour shapes.
Finally, Custom Seal-Cut (CSC) Band offers customization for demanding applications. This band combines a tapered band with a cutting wire, allowing manufacturers to tailor the width and cutting wire thickness to their specific needs. Cutting wires can be positioned along the centerline or at the edge of the band, enabling precise cutting action at multiple locations.
All TOSS seal and cut bands are designed to create consistent, repeatable seals every time, making them compatible with a variety of automated and customized impulse heat sealing systems. To guarantee the reliability of the seal, these bands, when paired with a PIREG heat seal controller, can include a heating and cooling cycle, ensuring the films seal completely before pressure is released.
