Abstract
The invention discloses a manufacture technology of a PU (poly urethane) dumbbell ball or dumbbell piece with a colorful logo. The manufacture technology is characterized by comprising the following steps of: firstly, carving a required logo shape in a mould, putting a blank of the dumbbell ball or the dumbbell piece into the mould, filling the color-mixed color pigment into a carved logo-shaped cavity, adding liquid polyurethane production material into the mould after a solidified layer is formed on the surface of the color pigment, assembling the mould after a solidified layer is formed on the surface of the polyurethane production material, carrying out a high-temperature vulcanization working procedure, opening the mould after the high-temperature vulcanization, cooling, and finishing to obtain a finished product. The manufacture technology provided by the invention is simple in technology, and easy to operate, and an integrated structure is formed by the colorful logo and the PU dumbbell ball or dumbbell piece, so that the problem that the colorful logo is easy to fall off can be effectively solved, and the quality and the level of the product can be improved.
