One-Shot Molding of Self-Gripping Fasteners
Inter-mold is a one-shot injection-molding process for making parts along with the designated gripping areas. The tiny hooks of the self-gripping fasteners produced by Aplix S.A., based in Le Cellier, France, are integrated directly into the molded parts. The molded parts not only are esthetically appealing; the molding process, which utilizes fixed and adjustable mold inserts, also eliminates the tedious gluing on of loop-and-hook fasteners. Compatible plastic resins include polypropylene (PP), polyethylene (HDPE, NDPE, LLDPE), polyamide (PA6, PA6.6), polyacetal (POM) and thermoplastic elastomers. The hooks are also shaped to be compatible with nonwoven, woven and knitted fabrics.
The company has developed special fastener systems for automotive interiors as well as support elements for the trunk. The technology also offers solutions for fastening the headliner. The loop-and-hook fasteners make it easier for professional cleaning staff to attach cloths and wipes. As the gripping areas have the same characteristics as the plastic, they are not affected by moisture, detergents or sterilization processes. Users should benefit from the large design freedom offered by the Inter-mold process, including medical technology applications.
Aplix also supplies a wide selection of hook-and-loop fasteners that are suitable for different attachment systems wherever the plastic used for a product does not allow the hooks to be injection molded.
