The manufacturing process of PA nylon hollow plastic pepper ball is that two hemispheres are welded by laser, while PP hollow plastic pepper ball is mostly manufactured by blow molding process, which has the characteristics of high efficiency and low cost. However, the PP hollow pepper ball manufactured by blow molding process has low precision and insufficient strength, which can not meet the needs of customers who require high quality of plastic hollow pepper ball.

PA plastic nylon hollow pepper balls are produced by laser welding process, which requires high investment in molds, tools and laser machines. Therefore, the manufacturing cost of PA plastic nylon hollow pepper balls is much higher than that of ordinary PP hollow pepper balls. However, PA hollow plastic pepper balls have the characteristics of high precision, good compressive strength, oil resistance, chemical resistance and high temperature resistance, and are still widely used in some industries, such as automobile industry and chemical industry.
