Plastic balls are deal for light load bearings and flow control applications.
Plastic balls are often used in the construction of office furniture and
medical equipment because of their quiet operation. Plastic balls are
often used extensively in pharmaceutical, food and chemical production.
Plastic balls are produced using standard and special polymer resins
with diameters from 2.0 to 15 mm. and they can be used instead of stainless steel
or steel balls in various industrial applications at lower cost than metal balls.

Production Line :
In the first step, heading machines cut wire into short lengths and form it into spherical shapes between dies.
The flash line, a ridge left by the forming dies, is removed as balls roll between heavy,cast iron plates.
Similar to deflashing, except that a grinding stone is used to improve precision.
Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.
This step removes the residues and by-products from the heat-treating process.
Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as closeas ±.0001".
Several proprietary lapping processes can bring balls to the requirements of ISO 3290 Grade10 - 48.
Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, for increased wear resistance and product longevity.
