Plastic Injection Molding with Polycarbonate

What is Polycarbonate?

polycarbonate sheets, injection molding

Polycarbonate is a naturally transparent, durable, easily molded material. The transmission of light through polycarbonate material is similar to that of glass making it a common choice alternative to glass in the manufacturing of plastic. Able to handle more stress than glass, polycarbonate is a chosen for products like bullet-proof glass and other products where transparency and impact strength are both needed.

What is Polycarbonate used for?

Another common example of polycarbonate is vehicle headlights, and digital casing. One product we currently make is a digital sensor that has a clear, polycarbonate “window” in the front for viewing purposes. Additionally, BPA-free versions of Polycarbonate have taken the marketplace of bottle and sippy cups. With its weather resistance, transparency, and light transmitting properties Polycarbonate is a good choice for other products as well, including but not limited to:

  • Greenhouse/Agriculture tools & structures
  • Aircraft and aerospace components
  • Electronic components
  • Automotive parts
  • Lighting
  • Machinery guard
