Plastic bull barrels - Profile of plastic bull barrels provided on the main highways and city roads prone to fixed installations in the automotive and road collision parts, such as: Road corner, path booth, toll stations and the elevated road import and export, parking, residential, garden, gas stations, etc., play a role in isolation, anti barrels are modified plastics high flexibility, high strength steel, when the vehicle collide with the device, can effectively reduce the impact force, So, can significantly reduce damage to cars and people. Its surface mount some reflective film, can be labeled instructions on the label as required plastic bull barrels - Overview of material: Imported PE Resin Specifications: High 800mm diameter 600mm description: furnishings convenience, impact resistance, aging, long life, excellent glass steel products, reduce traffic accidents, mainly applied to the bridge, crossing, toll stations, gas stations and material compositions. Plastic bull barrels good elasticity, high strength, high performance plastic made of a plastic bull barrels of barrels as yellow, the surface will affix advanced reflective film, when the light shines in the above can reach reflective effect, day and night clearly visible. Special functions inside the plastic bull barrels filled with water or sand, and the sand will be filled with who has the ability to slow down the impact force, the plastic bull barrels filled with water or sand for traffic collision force with a good effect, but when not needed after pouring water and sand can easily move very flexible. Some functional principle reflective film surface mount plastic bull barrels, day and night are clearly visible, can play a role in anti-collision warning. Accidental collision of the vehicle can play a buffer role, so that the vehicle is to minimize the damage, greatly reduced the loss of the accident. Plastic bull barrels - Classification plastic bull barrels blow molding and rotational molding can be divided into two kinds: blow bull barrels extrusion blow molding process consists of five steps: 1. plastic parison (hollow plastic tube extrusion); 2. In the parison fit the mold will flap closed, clamping the mold and cut the parison; 3. into the cavity of the cold wall blown type training, adjust the opening and during cooling to maintain a certain pressure; 4. open the mold, remove Under blown parts; 5. trimmed burrs to be finished. Rotational bull barrel rotational concrete steps can be dismantled: 1. feed: the weighed plastic material in the form of a liquid or powder into a mold cavity; 2. Heating: rotational molding machine with mold in both directions rotation, and join the furnace, the mold gets hot, all plastic adhesion and fired on the inner surface of the cavity; 3. Cooling: With the continuous rotation of the mold, the mold while feeding the furnace into a cooling chamber, cooling chamber in rotational molding plastic cooling; 4. Stripping: rotational molding machine to open position, stopping the rotation of the mold, the mold is opened, remove it. Zhengzhou takeoff transport facilities Ltd.
