A Vlier Success Story:The Impact of Ceramic

Vlier Ceramic Plunger Success Story

At Vlier Products, we’re never afraid to innovate—eighty years after we first arrived on the scene, we’re still creating new parts made of new materials that open us up to new markets. Our latest innovation is an off-the-shelf line of ceramic ball plungers, which are compact spring loaded devices frequently used in indexing, locating or positioning for a variety of applications. The product design automates and simplifies the assembly process for manufacturers, while the unique ceramic makeup allows engineers to meet the demands of extreme environments. Read on, as we look into how this innovation came to be and how our customers will benefit from the impact of ceramic.

Why Ceramic Plungers?

This undertaking began when we created a solution for an instrument used in spinal surgery for vertebral compression fractures. Our specially designed threaded plunger sets a critical torque value that is needed during the surgical procedure, as to ensure no injuries or damage to bone. At the same time, the hygienic nature of the ceramic ball made it ideal for use within a surgical setting. While this medical application was the catalyst for creating our new line of parts, the other inherent benefits of ceramic opened us up to an array of new industries.

Benefits of using ceramic material include:

  • Cleanroom compatibility
  • Corrosion resistance
  • Electrical insulation
  • Easily recyclable
  • Longer life than steel/other metals
  • Non-magnetic
  • Nearly frictionless
  • Lower weight than steel
  • Non-marking/marring
  • High-temperature tolerance
  • Enhanced thermal dissipation

The Features of Ceramic

The material we use for our parts, alumina oxide (Al2O3), isan industrial-grade ceramic defined by its high hardness and long-wearing properties. These unique features make alumina oxide ideal for parts that must remain durable under extreme conditions. Here’s a look at alumina oxide by the numbers:

  • 2,977: Melting point (°C)
  • 2,072: Boiling point (°C)
  • 2,000–4,000: Compressive strength (MPa)
  • 300–600: Mechanical strength (MPa)
  • 15–19: Hardness (GPa)
  • 3.95: Density (g/cm3)

The Future Impact

The inclusion of off-the-shelf ceramic products is a giant step forward for Vlier Products, allowing for an exciting expansion of our offerings and industry partnerships. Ournew line of ceramic plungers will help engineers meet specific criteria for temperature tolerance, chemical resistance, longevity and more.
