Rotary Technology

 
   
Wheel Technology - Transforming One Industry After Another
The highly innovative Graham Wheel quite literally reshaped entire packaging markets by redefining the standards for high volume, high quality production. Today, this technology is in production on nearly every continent around the globe. With over 250 wheel installations worldwide, the Graham Wheel represents the unchallenged standard for high capacity with superior quality standards

GEC Rotary machines process virtually any thermoplastic to produce containers from 100 ML up to 30 liters. GEC equipment conforms to all national and international safety and operating standards with certifications including OSHA and CE. GEC Rotary machines offer maximum flexibility for delivering ideal packaging solutions.

  • Indexing and continuous operating machines
  • Single and multi-cavity molds
  • Monolayer structures and coextrusion up to seven layers
  • In-mold labeling
  • View stripe enhancements
  • Aseptic blow Molding

GEC's worldwide network of sales and service professionals work closely with customers to identify and install optimal production-machinery solutions and to provide responsive 24-hour support for reliable, consistent production line performance.

Single Flow Head Configuration
Our unique single head design extrudes the parison in an upward fashion, which permits the bottles to be discharged under the wheel in a simple operation. The upward extrusion of the parison also permits the parison program cylinder to be mounted beneath the head, thereby avoiding any possible contamination of the plastic by hydraulic fluid.

Remote Die Adjuster
Our patented remote die adjuster allows the operator to fine-tune the head for precise sidewall distribution without tools, and while the wheel is running. 		 
     

Multi-Layer and View Stripe Options
All rotary machines are available with multi-layer and view stripe production capabilities. Our wide range of extruder sizes and flow head configurations allow up to seven layers of material distribution.

    Typical applications include:
  • Detergent bottles with virgin inner and outer layers and a post-consumer scrap middle layer
  • Motor oil bottles incorporating a view stripe
  • Agricultural chemical bottles with up to six layers, including a barrier layer
  • Food and beverage long shelf-life packaging
 
     
Double Parison
Recently developed dual parison technology doubles the output of GEC Rotary machines when producing smaller containers.

Electro-Mechanical Operation
GEC Rotary machines operate completely electro-mechanically for quieter, cleaner and more efficient performance. Hydraulics are required only for the parison programmer and are positioned safely away from rotary components. 		   
     
Modular Design
GEC packs a lot of production into its machines, with an emphasis on space-saving design.All machine controls, heaters and drives are mounted and prewired onto the extruder platforms for simple installation and maximum reliability.

Quick Changeovers
All GEC Rotary machines have an optional mold hoist available. With the use of the mold hoist, a two-person team can accomplish quick and safe mold changes in a very short time. Our streamlined flow heads allow unprecedented rapid color changeovers. Less downtime equals greater production runs.

In-Mold Labeling
All GEC Rotary machines - continuous and indexing - can be equipped with IML (paper or film), a production capability unavailable on most other machine systems. Labeling takes place with virtually no loss in cycle time and with precise and consistent label placement accuracy. 		 
     
One Conveyor, One Direction
Unlike dual station shuttle machines, our rotary machines require no reorienting state. Bottles exit the machine uniformly on a single conveyor.
