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 nearly 400 wheel installations worldwide, the Graham Wheel represents the unchallenged standard for high capacity with superior quality standards

GEC Rotary machines process a wide array of thermoplastics to produce containers from 100 ML up to 30 liters. GEC equipment conforms to many 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

Dual Parison
Dual parison technology can double 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
Many of our customers produce multiple containers on our rotary wheel machines. Some machines employ water lines into the platens, allowing rapid changeovers without water disconnects required. In other cases, GEC can employ our quick change "Shoe Mold" technology, allowing the removal of only the cavity insert ("shoe") portion of each mold when changing between products.

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.

GEC Rotary Deflash and Spin Trimmer with Trim Tooling
This proprietary technology provides the highest operational deflash trimming rates in the industry. This trimmer can handle speeds that would have required two or three linear deflash trimmers in the past.
Features include:
Horizontal, rotary based in-feed, deflash, transfer, trimming and out-feed sections
Spin trim or guillotine neck finish available - center or off-center neck
Mechanically cam driven actuation for long life and low maintenance
True perpendicular deflash - die tooling punches straight down on the container
Logs are fed into the trimmer from an accumulation queue via timing screws
Bottles exit the trimmer standing up (or laying down, if preferred), oriented as required

Rotary System Capabilities
Smallest Bottle - 82 ml (@ 7 grams)
Largest Bottle - 30 liter (@ 1,200 grams)
