Resin Conveying Systems commonly fit into one of the following four categories:      

  • Single Source - Single Destination: Extrusion, thermoforming, and injection (preforms)
  • Single Source - Multiple Destination: Extrusion, injection (caps), and blowmolding (containers)
  • Multiple Source - Single Destination: Extrusion
  • Multiple Source - Multiple Destination: Injection, extrusion (tubing, wire & cable)

Many crossover situations may affect the system selection process but typically...more(+)
