Nifco Inc. (Headquarters: Yokosuka City, Kanagawa Pref., President: Masaharu Shibao, hereinafter “Nifco”) recently developed a packing-less bumper retainer that achieves watertight performance without rubber packing and began mass production for Toyota Motor Corporation (hereinafter "Toyota ").
In recent years, where climate change has had a major impact on various parts of the world, the automobile industry is also making efforts to realize carbon neutral and circular economy. One of these efforts is to improve the recycling of automobiles.
The bumper retainer is a part used to attach an automobile bumper to the body, and that of Nifco has the unique feature of being fastened with one-touch plastic pin which does not need any power tools. In the past, rubber packing was placed between the fastening part (grommet) of the body and the retainer to prevent water leakage from the fastening part, but the newly developed packing-less bumper retainer achieves watertight performance by using a thin-walled flange molded integrally with the grommet, eliminating all the rubber packings. This will make it possible to create a single material (mono-material) including the plastic pin used in the fastening part, thereby improving recyclability of the product and contributing to the realization of carbon neutral and circular economy. In addition, eliminating the rubber packing assembly process contributes to labor-saving and automation of the bumper retainer manufacturing process.
This product is installed in Toyota Motor Corporation's new CROWN ESTATE and other models.
<Product Features>
・The body seating surface is arranged to surround the fastening part (grommet) on all four sides, so it can be stably attached to the body even in a small space, and the thin-walled flange molded integrally with the grommet ensures watertight performance *Patent pending
・Watertight performance is stabilized by deflecting the thin-walled flange using the pulling force of the grommet when the pin is pushed in
・No need for rubber packing, reducing the number of steps required to manufacture the bumper retainer and lowering product costs
・Body fastening without power tools makes it easy to dismantle, and reusable design realizes a long product life
・Promoting material recycling by using a single material (mono-material)
Align the grommet part with the fastening hole of the body, and push in the pin to fasten.
Nifco will continue to sincerely address issues from society and customers and contribute to the realization of various products that lead to a better environment, safety and comfort in order to realize our purpose of‘Sparking innovation by fastening small insights with technology for a better world’.
