Abstract

The invention discloses a plastic car stop device with imitation stone effect, which comprises a hollow base and a shell placed on the base, the shell is screwed to the base, and polyethylene powder with stone imitation effect is used for both the base and the shell It is made by rotational molding process, and the polyethylene powder with stone-like effect is mixed with polyethylene powders of different colors. The invention is processed by the rotomolding process, and the stone imitation effect of the outer surface is good, the pattern is obvious and uniform, and the visual experience is outstanding, which can avoid the pollution problems such as dust and noise during the existing stone carving process, and is light, easy to transport and install, and low cost. Low.

Description

technical field [0001] The invention relates to the technical field of production of rotationally molded products, in particular to a plastic car stop device with a stone-like effect. Background technique [0002] Rotational molding is a plastic processing method that uses a rotating mold for processing. The processing process is to put plastic powder or slurry into the mold, and the closed mold is rotated or shaken on the equipment, and the mold is heated by an open flame or hot air. External heating, the plastic powder or slurry is turned and flowed inside the mold under the heated state. After the temperature reaches the softening point, it is gradually coated on the inner surface of the mold, melted and condensed. The mold is placed in the natural environment or passed through water, After cooling by media such as fog and wind, the mold is removed and the product is taken out. More than 90% of products in rotational molding are processed with polyethylene powder. [00...
