Container Bottles Wholesale

(5) can be blow molded wall thickness of thin products, such products can not be molded by the injection method. (6) may blow molding complex shapes, irregular and a monolithic product. When using injection blow molding, to produce a first after two or more pieces, by snap formulation, solvent bonding or ultrasonic welding together. Injection blow molding is characterized by: (1) plastic melt is injected into the parison mold cavity in which the circumferential direction by a certain orientation effects. Further temperature of the preform blow than when extrusion blow molding lower, orientation effects can be produced by a blow to retain more down, these will help to improve the strength of plastic bottles and other properties. (2) plastic bottle size (especially the neck thread size) high precision, easier to bottle wall thickness required to ensure the uniformity of uniform size bottle. (3) bottles on the surface does not form joint seam after molding without finishing, generally do not produce corners more than expected, produced by extrusion blow molding scrap is usually 5 to 30%. (4) bottles high gloss, transparent polymer molded out of the bottle transparency significantly. (5) can be provided with a sliding block on the blow mold bottom, so the bottom of a larger bottle shape design flexibility. More suitable for molding hard plastic bottles and wide-mouth plastic bottles. (6) injection blow molding have a parison mold and blow mold two kinds of mold, and the mold demanding, so the higher the cost of injection blow molds, extrusion blow of about 2 to 3 times. Since the parison mold cavity a higher pressure on the melt (10 ~ 40Mpa), so the higher the residual stress of the blow bottle, the parison and the mold clamping force high requirements. By injection blow molding, most of the smaller volume of the bottle (typically 10mL-300mL), not molding the shape of complex products, energy consumption is significantly higher.

Cycle campus plastic beverage bottles recycling service design and analysis Abstract: plastic material is light, easy to process, product appearance a variety of excellent performance, affordable and so on. Movies child can be widely used in various fields of science and technology, and daily life. China's annual production of plastic has more than 20 million tons, however, the plastic is thrown away after use, cause serious environmental pollution. Further, since a large amount of discarded waste plastics, easily degradable, difficult to handle, affecting a wide range of serious pollution, known as the "white pollution." Visible, waste plastic bottle recycling for environmental protection, recycling use of resources, energy conservation has a great significance.
