Roll-on Applications

Precision balls are used most notably in the health and beauty or pharmaceutical  industries, in control-flow applicators for applying lotions, creams or perfumes. Hartford Technologies manufacturers polypropylene (PP), high density polyethylene (HDPE) plastic, or glass balls that are inert to most health and beauty solutions or creams.

Overview of Roll-on Applications

These roll-on applicators include a spherical ball within a chamber,  a spring-biasing valve in a second chamber,  and a sealing insert between the ball and the valve. The sealing insert is moveable allowing for between a flow passageway between the first and second chambers to open and close.

Materials for Balls for Roll-on Applications

  • Glass, plastic or stainless steel (polypropylene or polyethylene are most popular)
  • Sizes from 316″ to  3/4″ or 1″ (most popular is the 5/16″)
