Industrial Shot Pot Technology

 

 
  The Graham Shot Pot Industrial Blow Molding Machine can be constructed and provided with one- or two-layer parison configurations. These systems can be supplied with three or five parison heads based upon customer needs on specific applications.

These machines are designed to make parts with large annual volumes.
The secondary Shot Pot stores the entire shot capacity required for each head and cycle. The material stored in the shot pot is allowed to “relax” between shots – reducing the residual “stress” in the plastic, and allowing for a smooth and high quality parison to be extruded

Some applications for this technology are:

Consumer goods run in multiple colors (fast changeover and colorant cost savings on multi-layer head

Automotive and consumer applications where both structural and decorative layers are required (soft touch material over PP Base; vinyl co-extrusion... etc)

High-volume, multiple-cavity consumer/industrial products where reduced labor costs and increased efficiencies are required to combat price reduction from foreign or domestic competition.
