Method for wrapping edge of PEAK racket

Abstract

A method for wrapping an edge of a PEAK racket by injection molding is provided. The method includes the steps of manufacturing and preparing a preliminary embryo of a racket, where the preliminary embryo of the racket includes a racket body and a handle that is integrally connected to the racket body; mounting a racket mold on an injection molding machine, and placing the preliminary embryo of the racket into the racket mold; placing plastic particles into the injection molding machine, to melt the plastic particles in a liquid form, where the liquid plastic flows into the racket mold and is combined with a peripheral side surface of the preliminary embryo of the racket, to form a wrapped edge; and after cooling, wrapping the wrapped edge, and fastening the wrapped edge to the peripheral side surface of the preliminary embryo of the racket to form a finished product.

Claims

[0015] FIG. 2 is a sectional view taken along line 2-2 of FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Referring to FIGS. 1 to 2, a method for wrapping an edge of a PEAK racket by injection molding according to the invention comprises the following steps.

[0017] (1) Manufacture and prepare a preliminary embryo of a racket 10, where the preliminary embryo 10 of the racket includes a racket body 11 and a handle 12 that is integrally connected to the racket body 11. Specifically, the preliminary embryo 10 of the racket includes a substrate layer 101 and two panels 102. The two panels 102 are respectively stacked on two surfaces of the substrate layer 101. A structure is simple, and manufacturing is convenient. The substrate layer 101 is made of a foam honeycomb material, and the panel 102 is a glass fiber panel or a carbon fiber panel.

[0018] (2) Mount a racket mold on an injection molding machine, and placing the preliminary embryo 10 of the racket into the racket mold. In this embodiment, the injection molding machine is a vertical injection molding machine, to perfectly perform wrapping on the preliminary embryo 10 of the racket by injection molding.

[0019] (3) Place plastic particles into the injection molding machine, to melt the plastic particles in a liquid form, where the liquid plastic flows into the racket mold and is combined with a peripheral side surface of the preliminary embryo 10 of the racket, to form a wrapped edge 20.

[0020] (4) After cooling, wrap the wrapped edge 20, and fastening the wrapped edge to the peripheral side surface of the preliminary embryo 10 of the racket, to form a finished product, and taking out the finished product from the racket mold.

[0021] Key points of design in the invention are: The wrapped edge is directly molded on the peripheral side surface of the preliminary embryo of the racket by injection molding, to enable the wrapped edge to be well fastened to the peripheral side surface of the preliminary embryo of the racket. This replaces a conventional manner of first molding the wrapped edge and adhering the wrapped edge by using the strong glue. According to the invention, the strong glue does not need to be used, so that production efficiency is effectively improved. In addition, a plastic material used may be recycled, without using the strong glue, so that the method is more environmental-friendly, and appearance of the racket is more beautiful and comfortable.

[0022] The technical principles of the invention are described above with reference to the specific embodiments. These descriptions are merely intended to explain the principles of the invention, and may not be construed as limiting the protection scope of the invention in any way. Therefore, those skilled in the art may derive other specific implementations of the invention without creative effort, but these implementations should fall within the protection scope of the invention.

[0023] While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
