Blow-molding Process

The blow-molding technique is a versatile process whereby air pressure is used for blowing hot plastic into the cavity of a mold. This process has the advantage of producing more rigid and lighter parts than other plastic-manufacturing techniques.

The Advantages

  • Lightness
  • Inherent mechanical structure
  • Impact absorption
  • Possibility of making parts multifunctional
  • Profiled finish on all surfaces
  • Secure parts with smooth edges and without chinks
  • Quality and consistency of surface finishes
  • Insulation
  • Ability to contain, circulate and support
  • Possibility of obtaining single- or double-walled parts
