Super-large soluble plastic pepper balls refer to plastic pepper balls with a diameter between 40 mm and 125 mm. Generally, soluble plastic pepper balls smaller than 20mm are produced by injection molding, and super-large plastic pepper balls are generally produced by bar machine processing.Plastic plastic pepper balls are relatively easy to manufacture because they don't need to be dissolved in fracturing fluid, because there are many kinds of plastic bars in the market, which basically cover all kinds of plastic raw materials. To manufacture insoluble plastic pepper balls, you can choose bars according to the required physical properties, but the main material of soluble fracturing balls is PLA material, and there is no ready-made bar in the market, so PLA super-large soluble pepper balls have always been a difficulty in manufacturing. If you want to process PLA super-large soluble pepper balls, you need to make PLA bars first, which need a professional extruder to make. Because of the high shrinkage rate of PLA materials, it is easy to produce air holes in the middle of the bars, and the surface of the bars will shrink, which will cause the surface of the bars to collapse. Dongguan Jiaji Plastic Products Co., Ltd. has finally developed bars that can be processed into various specifications of PLA soluble pepper balls through years of research and development and practice. At present, the PLA soluble fracturing balls processed from the bars have been recognized by many customers and welcomed.
