Vacuum System Types
Plastics conveying systems commonly fit into one of four following categories and are typical for certain processes. Some exceptions are common and may occur.
• 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)
There are many crossover situations that may affect the system selection process but typically the processor listed in the above business will employ the type of resin conveying system shown.
Here are some additional factors to take into consideration:
All of these questions are best discussed with a systems engineer who will help guide you through your selection process.
There are also sub-systems which are usually considered separately but can be integrated into the primary resin conveying system.
When considering a central resin handling system, it’s best to include all parts of the process if possible. Anything you can do to declutter the production floor results in a better workflow, fewer employees and increased profits.
