Plastic road barriers are mainly used in traffic, pedestrian streets, banks, airports, and roads. They play a wide range of functions. They can ensure the safety of the site, and can also restrict the passing of vehicles, and the order of the roads can be improved. Although there are many types of roadblocks, plastic roadblocks are the most common one.
The plastic road barriers is formed by rotomolding process and rotomolding mold, mainly because the cost of rotomolding mold is low: the product of the same size and size, the cost of rotomolding mold is about 1/3 to 1 of the cost of blow molding and injection molding. 4; and the plastic barrage edge of the rotomolding is good in strength, and the thickness of the edge of the product can be more than 5 mm, completely solving the problem of thinner edges of the hollow product.
The plastic road barrier shape of the rotomolding product can be very complicated and the thickness is more than 5 mm. In addition, the mold does not need to be adjusted during the production process. The wall thickness of the plastic barrier can be adjusted freely, so that the product has high strength and meets the plastic road barriers in different situations. Under the use requirements.
