Another name for PP is PP plastic plastic float ball, because the proportion of PP plastic ball is lighter than water, can float on the water, so called PP plastic float, PP plastic has great relation to the buoyancy of the floating ball size and production technology, as a professional production of plastic ball manufacturers, Dongguan good skills plastic products Co. Ltd has accumulated rich experience in this aspect, specific methods need several aspects together to complete, the first is PP plastic ball mold do not exhaust, so that the cavity has a certain gas, if you need a PP plastic ball has great buoyancy, but also to increase the flow of plastic ball mold, so on the cavity is there enough air, the second aspect is the injection molding machine by adjusting the parameters of the injection molding machine speed fast, so that the rubber ball, plastic ball mold in the air because there is no in time. Outside the mold, and residual bubbles form in the product, such production of PP solid plastic ball buoyancy increased significantly, even to the buoyancy of the hollow plastic ball, but this production technology in the production of PP plastic float process is not stable, unless the silica gel products factory has rich experience in production to be completed, with the same principle, rubber ball can also refer to the production process of PP plastic floating ball, can also produce rubber ball float, but rubber ball float process is still in the process of exploration, I believe the near future will be able to are the same as on the production with PP plastic float buoyancy of the rubber ball
