Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method of manufacturing a badminton head, and more particularly to a method for making the weight and hardness of a badminton head product in a predetermined standard range. [Prior Art] The badminton head according to the prior art is mainly made from the stem of a plant, such as a cork shape, and then cut with a standard size badminton head cutting tool, and is ground to make a round head shape at one end, and evenly outside. The adhesive was coated with a PU-coated artificial leather, and the other end of the circumference was fixed by 16 feathers. However, there are fewer and fewer natural corks. It takes several years from planting to cutting the valve. It has not been able to supply a large number of markets, and the cork plate after manufacture has the same processing conditions because of the different cork size. Badminton heads of different hardness and density are produced so that the weight cannot be controlled to a preset standard, and the manufacturing process is too time-consuming and laborious. Therefore, the industry has appeared in the plastic foam material, the use of mold foaming to form a badminton head, and then coated with a layer of PU artificial leather, but because the foaming process is not easy to control, so that its finished products often have excessive weight or Insufficient to form too many defective products, and the hardness is not enough, so that the implanted feathers will be problematic due to the looseness of the foundation. Since the speed is closely related to the weight of the ball, a slow ball such as 76 has a ball weight ranging from 1.5 mg to 1.6 mg, a medium speed of 77, and a ball weight of 1. 7 mg to 1.8 mg. 'Fast 78 ball weight is 1.9 mg. To 2.0 mg, it can be seen that the density and weight of the badminton head will affect the speed of the ball. It must be controlled within a certain range of 5 201000174, which is easy to cause a large number of defective products, and the density of the badminton head made by the conventional plastic foaming method. Not enough to cause too light, it will be difficult to plant hair because the base is too loose. SUMMARY OF THE INVENTION Accordingly, the main object of the present invention is to provide a method for badminton head garment k, which can be made into a feather with a uniform twist and a weight that can be controlled within a preset standard range _ 'and the appearance is not too smooth It can eliminate the trouble of coating a layer of pu artificial leather, save material cost, and manufacture quickly and economically. It can be seen from the above that, in order to achieve the above object, the present invention provides a method for manufacturing a badminton head, which comprises preparing 8 (four)% of a polyethylene-based foaming material (Polyethylene modifier), 8~1%%#, and 2% titanium dioxide, put the above ratio of plastic foaming material, foaming agent and white powder into the mixer to make the mixture evenly, and then use a kneading machine to cover it for 20 minutes, then smash the mixture completely. Re-investment - granulator gripped into plastic granules 'prepared - shot into lai' will pour Na granules into the hopper of the injection molding machine, the injection temperature is controlled at 13 摄 Celsius. 〇 to 16〇t: between, and let the material stay in the mold towel for 45 seconds, the inside of the miscellaneous tool is provided with an S-shaped pipeline for cooling fire to be poured into the cooling water of 5 c Celsius for about 3 seconds, and the mold can be opened. The finished product is taken out, thereby obtaining a badminton head having a weight and hardness in a standard range. The invention can obtain the following advantages: 1. Since the badminton head finished product taken out by the mold of the invention is rubber 6 201000174, the foam material is expanded in the high temperature mold and filled in the whole mold, and the mold is opened to take out the finished badminton head, and the surface thereof has been For rough surfaces, no need to apply any more - layer PU artificial leather' to save costs. 2. After the material of the invention is poured into the mold to be expanded and formed, the internal pipe of the mold is further poured into the cooling water to rapidly cool down, so that the density of the finished badminton product can be tight and uniform, and the hardness and weight can be controlled within a preset standard range. 3 The mold of the badminton head mold cavity with the injection molding die of the invention can be produced in a large amount, which is economical. [Embodiment] Please refer to "Fig. 1", a method for manufacturing a badminton head according to the present invention, comprising: a: preparing 88 to 90% of a nano polyethylene modifiers compound, 8 to 10% a foaming agent, and further adding 2% titanium dioxide; b: putting the above ratio of polyethylene plastic foaming material, foaming agent and titanium dioxide into a mixer to make the mixture uniform; c: preparing a kneading machine to mix the above After the foaming material is put into the kneading machine at 12G ° C for four (four) minutes, the material is completely smashed into a dough; d. A granulator is prepared, and the material of the above-mentioned mashing group is put into a granulator to form a plastic.粒: e: prepare an injection molding machine, the mold is internally provided with an s-shaped pipeline for cooling water, and has 16 annular rows of badminton heads, and the plastic 201000174 rubber particles are poured into the domain forming machine. The hopper is controlled by the Celsius to (10). Between c, the material is sprayed into the mold, and the material is allowed to stay in the mold for a second. Then, the cold water of 25 C is poured into the pipeline of the mold for about 3 seconds; : Open the mold 'take out the finished badminton head. By virtue of this, it is possible to obtain a uniform badminton head with a weight ride in the standard range and a suitable roughness on the surface, without having to cover the layer pu artificial leather and the badminton method of the known. cut costs. The invention has the following advantages: 1 The invention is input into the injection & molding machine human hopper (4) plastic granules are .90% nano-grade polyethylene to foamed materials (10) ye 御 (10) _fiers co_und) and 8~1〇% hair Foaming agent, and then adding bismuth titanium dioxide component, in the input (four) into the surface 魄 high temperature recorded, and then squeezed into the fixture to expand and fill the whole side, (4) the mold to take out the badminton head finished product, the surface has been The foamed surface has a rough surface that is not too smooth, so it is no longer necessary to apply a layer of pu artificial leather on the surface to achieve cost saving. 2. The invention is in the material input and injection molding machine, which is melted at a high temperature and then extruded into a mold. After being expanded and formed, the s-shaped pipeline inside the mold is further poured into the cooling water, which can rapidly cool down, so that the density of the finished badminton product is tight. Uniform, can control its hardness and weight within the preset standard range, 俾 reduce defective products, and benefit 8 8 201000174 for subsequent implantation of feathers. 3. The injection molding die of the present invention is a mold having 16 feathers arranged in a circular shape, which can be produced in a large amount and is economical. In summary, it is known that the present invention has industrial applicability, novelty, and advancement, and meets the requirements of the invention patent, but the above is only a comparative example of the present invention, and is not intended to limit the present invention. The scope of the invention. That is, the equivalent variations and modifications made by the scope of the present invention are covered by the scope of the present invention.
