• Injection Blow Molding (IBM)
  • Extrusion Blow Molding (EBM)
  • Injection Stretch Blow Molding (ISBM)
  • Reheat Stretch Blow Molding (RHSB)

These terms are used on a daily basis in the plastic blow molding machine business.  They can be very confusing to blow molding machinery users.

Many users mix up Injection Stretch Blow Molding (ISBM) and Injection Blow Molding (IBM) in particular.  The difference between these two is the word “stretch”, which refers almost exclusively to PET which is stretched to give added strength.  HDPE and PP are rarely “stretched”, but injection blow molded without “stretch”.  The neck is injected, and the body blown in the same process (IBM).
