Rotational manufacturing process: a thermoplastic hollow rotational molding method. Including PE rotational molding powder and other water horse bull barrels, slush and liquid monomer PVC paste resin molded polymeric three rotational molding. Rotational molding three different characteristics, but always the same principle. That is the first powder or paste or monomer materials injected into the mold, by heating and biaxial roll rotation of the mold, so that the material by its own gravity uniformly covered with mold cavity and the melt, after cooling to give a release hollow products. Rotational speed is not high, the product almost no internal stress transportation equipment bull barrels, deformation, dents and other shortcomings unlikely to occur. Originally mainly used for the production of PVC paste plastic toys, ball, bottles and other small products reflective bull barrels, recently on a large article may also have more applications, the use of resins are polyamide, polyethylene, polystyrene modified poly carbonate. Installation location: mainly used for urban intersection, highway crossings, toll lanes, gardens, residential, parking, garage, gas station entrances, downhill on the ground and other places. Installation: Installation more convenient, usually block any combination of standard methods and advanced "inner expansion anchor technology" bull barrels, screws firmly fixed on the ground, install a solid, stable and reliable vehicle collision will not loose . Role: to remind drivers to slow down, when the car passes silencer and recovery capabilities, to prevent traffic accidents do not occur in time to brake. Some deceleration zone inlaid with reflectors at night will reflect light, can attract drivers to pay attention, reduce speed and increase safety.
