Abstract

The invention discloses a plastic vehicle blocking device having an effect of stone imitating. The plastic vehicle blocking device comprises a hollow base and a housing arranged on the base, wherein the housing is in screwed connection with the base; the base and the housing are manufactured by using polyethylene powder having the effect of stone imitating through a rotational molding forming technology; and the polyethylene powder having the effect of stone imitating is formed by mixing polyethylene powder in different colors. The plastic vehicle blocking device disclosed by the invention is processed by the rotational molding technology, so that the external surface of the plastic vehicle blocking device is good in stone imitating effect, obvious and uniform in decorative patterns, and outstanding in visual feeling; the problem of pollution of dust, noise and the like during processing of a conventional stone material carving technology can be avoided; and besides, the plastic vehicle blocking device is light, easy to transport and mount and low in cost.

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...
