Solutions for Thin Wall Injection Molding

Save Material and Reduce Cycle Time

With over 20 years’ experience of thin wall injection molding, we have designed two dynamic and high-precision powerhouses - our hybrid and all-electric machines e-speed and e-motion. They are especially suited for applications with high or extreme flow-path to wall-thickness ratios. Thanks to iQ motion control, the powerful clamping unit offers up to 12% shorter dry cycle times at the push of a button.

e-speed:
Thin-wall injection molding with maximum performance

  • Hybrid high-performance injection molding machine

  • For the highest flow path-to-wall thickness ratios

  • For direct injection molding of rPET

  • Extremely short injection times < 0.05 s

Your Advantages with ENGEL Solutions for Thin Wall Injection Molding
All-electric clamping unit for short cycle times
Picture shows toggle clamp unit

For the requirements of thin wall injection molding, we have developed a clamping unit with an encapsulated five-point toggle. This not only ensures dry cycle times of well under two seconds, but also perfect cleanliness in the mold area. All moving elements, as well as the ejector, are sealed and prevent the formation of oil mist or dirt accumulation.

Reduced production costs thanks to electric drives

Water-cooled servo-electric drives make the injection molding machine the perfect synergy of efficiency and maximum performance. Reproducible cycles ensure consistent part quality for your thin-walled plastic parts.

Process reliability thanks to customized injection units

We have developed dynamic and precise all-electric and hybrid injection units for the production of thin-walled plastic parts. Specifically designed plasticizing components ensure high melt quality for typical thin-wall injection molding materials. Extra powerful servomotors and hydraulic accumulators ensure reliable cavity filling even with extremely high flow path-to-wall thickness ratios and shortest injection times.

Increase the availability of your production plant

Short cycle times require machinery with high dynamics. Large batch sizes mean continuous operation 24 hours a day, 7 days a week. Like our machines, our service team is available 24/7. If downtime occurs, production of thin-walled plastic parts can start up again quickly.

Greiner – Leader in Thin-Walled Packaging

Greiner Packaging was able to reduce wall thickness of food containers by a quarter with e-speed injection molding machines from ENGEL. At the same time, efficiency was increased. Climate neutrality is the goal of the Austrian packaging manufacturer.

Production of Thin-Walled Plastic Parts
  • All-electric thin-wall injection molding

    The high-performance injection unit of the e-motion enables the production of thin-wall packaging with a flow path to wall thickness ratio > 1:400.

  • Thin Wall Injection Molding with Stack Mold

    Margarine cups made of polypropylene are produced on our e-speed injection molding machine with integrated in-mold labeling (IML).

  • Thin Wall Injection Molding with In-Mold Labeling
