Blow Molding 101

Why choose blow molding?

• Blow molding tools can be made with lower cost blow molds.
   
• Blow molding is very well-suited for manufacturing hollow plastic parts.
   
• Blow molding allows for either double or single walled designs.
   
• Blow molded parts can be light weight, yet strong and durable.
   
• One blow molded part can replace several single parts glued or
  welded together.
   
• Blow molding usually costs less than injection molding.
   
• Blow molded parts usually cost less per piece than rotational molded
  parts due to faster cycle times.
   
• Blow molding is ideal for airtight or liquid filled containers.
   
• Blow molding works well for high or low production rates.
   
• Blow molding allows for flexibility in design change, and at less cost
  than other processes.
   
• Blow molding allows parts to be made from a wide variety of materials
  for strong part performance, durability, and high impact resistance.
   
• Blow molds are the most cost effective way to create hollow plastic parts.
  Blow molded parts are made by extruding hollow molten plastic between
  two mold halves. When the mold is closed, air is injected into the mold
  and forces the plastic to conform to the shape of the mold cavity.
