Technical Uses for Plastic Balls

Specific tolerances, resistance to pressures and over 40 years providing repeat business to hundreds of manufacturers, means we have excellent knowledge and experience providing balls for technical uses.

We pride ourselves in having over 40 years’ experience advising our clients and ensuring you have the best materials for the job.

  • Our tolerances start from +/-0.002”(+/-0.05mm)
  • Over 20 materials in stock
  • Materials specifically designed for resistance against heat, chemicals and pressure.
  • Sizes ranging from 1mm to 8” diameter
  • Plastic balls are light with a specific gravity ranging from 0.40g/cc to 2.14 g/cc
  • Low modulus in elasticity can assist in reducing noise levels and reducing the need for finer tolerances associated with metal balls.
  • Rust proof with a good resistance to chemicals and erosion.
  • Good electrical insulation properties
  • Non-lubricating
  • Non-magnetic

Production Method

Once the balls have been formed, usually through injection moulding, they are fine ground, lapped and sometimes tumble polished to a finished diameter – final tolerances are dependent on size and material type.

    Superb thank you,  I know your Company is conspicuously speedy in response and efficient I must say. I’ve placed orders many thousand times greater than this and observed a fraction of the efficiency.
