Method for embedding fastening piece to seat cushion

Abstract

The method for embedding the fastener into base pad includes the following steps: mounting the metal support component into slender groove formed on the metal mould; sticking the fastening hook element or gross ring element of the fastening hook gross ring fastener on the surface of metal support component by means of adhesive; fixing the first combined fastener element on the fastener element stuck on the metal support component; heating metal mould, injecting the foaming material formed from resin composite, foaming agent, lubricating agent and stabilizing agent into the metal mould to form base pad; removing base pad from metal mould so as to remove the fastener element embedded into the base pad from the combined fastener element stuck on the metal mould; then sewing second fastener element combined with first fastener element embedded in the base pad on the internal surface of base cover so as to make first fastener element fit with second fastener element.

Description

technical field [0001] The present invention relates to a method of embedding fasteners into seat cushions, and more particularly to a method of embedding fasteners into foamed articles such as seat cushions by molding. Background technique [0002] Today, hook and loop fasteners such as "Velcro TM "Fasteners are used to fix the seat cover to the car seat cushion. In addition, various foam products such as seats need to be integrally molded with snap-and-loop fasteners during the molding process. [0003] In the process of molding the foamed product with the hook and loop fastener, a specific process needs to be carried out to facilitate the fixing of the hook and loop fastener on the metal mold and prevent the snap and loop fastening The foam material penetrates into the hook elements or loop elements of the piece. That is, the metal plate is arranged on the hook element or the loop element of the hook and loop fastener, and the metal plate is coated with a thin film coat...

AI Technical Summary

Problems solved by technology

[0004] However, when removing the thin film layer made of thin film coating material or soft magnetic coating material, or when removing other complementary fittings of the hook and loop fasteners locked with the seat cover, due to the embedding into the hair Any element of a hook and loop fastener in a foamed product is subjected to high forces, so that the hook or loop elements of a fastener embedded in a foamed product can be damaged, or damage the support Foam for fasteners, thereby separating the fastener elements from the foamed article

Therefore, hook and loop fasteners cannot be used for a long time

In addition, since the coated film material is discarded after the foamed product is unloaded from the metal mold in order to facilitate the connection of the hook and loop fastener with other foamed products, it is necessary Application of new thin-film coating materials or soft magnetic coating materials, which increases production costs
