Plastic balls are widely used in bearings. POM and PA plastic balls have good mechanical strength and wear resistance. They are suitable for making more precise plastic bearings. The specific gravity of the plastic balls is 1.41-1.43 g/cm3, and the working temperature is from -60 to 120 degrees, the... read more
Production process of hollow plastic balls 1. Use injection or blow molding to form a hollow plastic ball embryo. 2. Clean the nozzle of the hollow plastic ball. 3. Roughly grind the hollow plastic balls, put the spherical blank into the two concentric ring-shaped grinding discs with the same size a... read more
First, make the mold according to the size of the plastic ball. What equipment is needed to make the plastic ball are as follows: injection molding machine and blow molding machine, punching machine, mixing machine, ultrasonic welding machine, polishing grinder, measuring instrument, etc. The most i... read more
In the ball mill, through the impact and peeling of the medium (steel balls, steel forgings, steel rods) and the ore itself, the particle size of the ore is further reduced until the powder is ground into work. The purpose is to achieve the ultimate separation of useful minerals and gangue minerals ... read more
Stainless steel ball is made of stainless steel cable produced and processed into spherical steel. Diameter is one of the application parameters of steel balls. So, how can the diameter of the steel ball ensure the same size? In order to control the diameter of the steel ball, first adjust the speci... read more
