Plastic pepper balls and plastic hollow pepper balls are widely used in industry and manufacturing, and there are irreplaceable plastic pepper balls in some specific fields. According to different plastic materials, plastic pepper balls are used in different occasions. Some plastic pepper balls have good oil resistance and temperature resistance, while others have low density and can be used as plastic floating balls. Because of different plastic materials, plastic pepper balls are different in hardness and surface smoothness.
First, the material:
There are dozens of varieties of plastic materials used for plastic pepper balls. Generally, the commonly used materials that can produce precision plastic pepper balls are PP (polypropylene plastic pepper balls), POM (polyoxymethylene plastic pepper balls) and PA (polyamide plastic pepper balls). PP plastic pepper balls have a high environmental protection level, which can meet the FDA standards of the United States and can be used in food and medicine fields. POM plastic pepper balls have the same hardness and good surface smoothness, and are widely used in plastic bearings and slide rails. PA plastic pepper balls.
Second, ordinary plastic pepper balls (toy plastic pepper balls)
Plastic pepper balls used in toys require environmental protection and safety and low price. Some toy plastic pepper balls are disposable products, such as children's toy gun bullets, which require environmental protection and low price. The materials that can produce toy plastic pepper balls mainly include PP materials and ABS materials, and also use PS materials to produce toy plastic pepper balls.
Three, plastic pepper ball precision and appearance quality:
Most customers who require high precision of plastic pepper balls are mechanical, which makes the plastic pepper balls have a functional function. The precision of plastic pepper balls is the tolerance of diameter. Generally, the tolerance of the diameter of plastic pepper balls is controlled within 0.01. The surface smoothness of plastic balls depends on the hardness and polishing technology of materials. Generally speaking, the surface polishing smoothness of materials with high hardness will be better, and there is the choice of abrasives. Plastic pepper balls with different plastic materials should match different polishing abrasives, only.
