For Precise, Dustproof and Watertight Connections: The Folding Frame Solution from Schreiner ProTech

In all industrial sectors, components made of diverse materials are joined together for a wide range of purposes such as protection, sealing and enhancing aesthetic appeal. Industrial component connections have to be temperature-resistant and long-lasting. Especially for customers from the automotive and electronics industries, Schreiner ProTech has developed a novel solution for bonding components. The patent-pending Folding Frame Solution provides a more efficient and effective alternative to conventional joining methods such as liquid gluing, bolting, soldering, riveting, single strips of adhesive tape or frames created from full-surface cutouts and eliminates their disadvantages.

Possible Methods of Bonding Components

Bonding of diverse components requires utmost precision to ensure that the parts are accurately and neatly placed on top of each other in order to guarantee perfect functionality of the final product. Adhesive frames created from full-surface cutouts are commonly used for this purpose, but produce a lot of waste. The material is typically available only in the form of single units or sheets. Due to this form of delivery and the frame dimensions, automated solutions are expensive while in manual processing, the risk of faulty adhesive bonding cannot be excluded. By contrast, the utilization of adhesive tape saves material, but in manual processing leads to small gaps or overlaps in corners. As a result, the component connections are neither watertight nor dustproof. Liquid gluing is another method that can be used to connect complex geometries. However, the curing times of liquid adhesives slow down the assembly process and their flow behavior usually prevents accurate and clean adhesive bonding. 

Benefits of the Folding Frame Solution

With its foam-based adhesive tapes, the Folding Frame successfully meets industrial demands for fast-curing and clean adhesive solutions, and eliminates the complex cleaning requirements following the use of liquid adhesives. Thanks to the matching Folding Frame System, the Folding Frame can be precisely positioned to ensure the component’s subsequent functionality. The Folding Frame Solution is suitable for semi-automatic or fully automated processing of roll-fed materials, which saves time and costs, and reduces the risk of defects that may occur in manual processes. 

Due to the production of a foldable adhesive version instead of a frame created from a full-surface cutout, multiples can be achieved more efficiently and material consumption significantly reduced for sustainable and eco-conscious manufacturing.  Self-adhesive bonding solutions support the lightweight design megatrend and replace bolted, riveted and soldered solutions. In addition to bonding and sealing, foam-based adhesive tapes make it possible to equalize uneven areas or height differences and reduce noise. 

Schreiner ProTech together with the Schreiner Services Competence Center offers customized system solutions. The product solution and matching processing system are supplied by a one-stop shop.
