The invention discloses a manufacturing method of a
steering wheel cover, wherein the manufacturing method comprises the steps of: a. preparing raw materials; step b. putting dried raw materials into a material inlet box of an
injection molding machine; step c. heating an injection molding
heating system to the temperature of 180-210 DEG C, then melting the raw materials, operating the
injection molding machine, and carrying out butt jointing on a mouth hole of the
injection molding machine and a glue inlet hole of a molded cavity of the mold; step d. injecting the melted raw materials into the molded cavity of a
steering wheel protection cover, and cooling and molding after to-be-melted materials fill up the molded cavity of the
steering wheel cover; and step e. taking out a product after being molded, thus the product is manufactured, wherein the raw materials and the composition proportion of the step a are as follows: 55% of
polyester polyol, 25% of water-base resin, and 20% of 1, 4-dyhydroxy hydroxy
butane. The invention also discloses the steering wheel cover and a special mold thereof. The steering wheel cover provided by the invention has the advantages of good environment-friendly effect, safety, beauty and elegance,
dirt prevention, easiness in cleaning, convenience in installation, comfort handfeel, high touch sense, and the like.
