Background

Expendable polystyrene (EPS) beads are tiny plastic beads that many plastic product manufacturers use in injection molding machines. Many plastic products utilize EPS beads in the manufacturing process. Quickdraft has worked with customers across the US to develop Venturi eductor systems to correctly and seamlessly convey EPS beads.

Problem

When working with these tiny plastic beads, it all begins with an expander, which makes the beads. The beads are discharged from one end of the expander, drop down into an air conveying system and are conveyed pneumatically through ducting to a large storage silo. A secondary system then conveys the beads from the storage silo to multiple hoppers at the front of injection molding machines.

In this process, not only do the beads need to be conveyed seamlessly from start to finish, they must be conveyed without damage or trauma, which can change the density of the bead. Any damage or density change to the beads can affect the end product, which can result in weaknesses or defects.

Solution

Many times, manufacturers will convey EPS beads with an inline fan. The beads must then pass through the impeller of the fan unit, often resulting in damage to the product.

A Quickdraft Venturi eductor eliminates any problems caused by an inline fan. With no moving parts in the conveyer stream, there is no need for the beads to pass through a fan impeller and risk damage. Plus, Quickdraft Venturi eductors are virtually maintenance free, which means no costly downtime or wasted man hours.

Results

Our customers continually report that Quickdraft Venturi systems work seamlessly with their manufacturing processes. They appreciate that there is little to no maintenance or repair time needed for the unit, and that their product is conveyed correctly, without damage, through their manufacturing process.
