产品采用韩  PE材质，而pe材质浮体、浮筒、浮球、浮漂、浮标采用滚塑工艺次成型-滚塑成型又称旋塑、旋转成型、旋转模塑、旋转铸塑、回转成型等，英文表达为ROTATIONAL MOULDING。滚塑成型工艺是先将塑料原料加入模具中，然后模具沿两垂直轴不断旋转并使之加热，模内的塑料原料在重力和的作用下，逐渐均匀地涂布、熔融粘附于模腔的整个表面上，成型为所需要的形状，再经冷却定型而成制品.使用寿命可达20年以上，性价比高。具有低成本、高质量和良好的长江南京以下深水航道建设工程指挥部召开本次会议旨在深入贯彻落实国家“依托长江黄金水道，建设长江经济带”发展战略，进一步加强多方合作，集思广益，共同做好南京以下深水航道及航道整治建筑物保护工作海洋聚乙烯浮球厂家 500mm警戒球50cm浮球价格

The products are made of Korean PE. The floating bodies, buoys, buoys, floating balls, floating buoys and buoys of PE are made by rotational molding. Rotational molding is also called rotational molding, rotational molding, rotational molding, rotational casting, rotational molding and so on. The English expression is ROTATIONAL MOULDING. Rotary molding process is to add plastic materials into the mold, and then the mold rotates along two vertical axes and makes it heated. The plastic materials in the mold are evenly coated and melted and adhered to the whole surface of the mold cavity under the gravity and action, forming the desired shape, and then cooled and finalized into products. Life expectancy can be more than 20 years, high cost performance.
