Solutions for Thin Wall Injection Moulding

Save Material and Reduce Cycle Time

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

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

  • Hybrid high-performance injection moulding machine

  • For maximum flow path to wall thickness ratios

  • For direct injection moulding of rPET

  • Extremely short injection times < 0.05 s

Your Advantages with ENGEL Solutions for Thin-Wall Injection Moulding
Short cycle times thanks to all-electric clamping unit
Picture shows toggle clamping unit

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

Reduced production costs through electric drives

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

Process reliability thanks to customised injection units

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

Increase the availability of your production plant

Shortest cycle times require machinery with high dynamics. Large batch sizes mean continuous operation 24/7. Our service experts are like our machines - available to you round the clock. So that if the worst comes to the worst, production of thin-walled plastic parts can start up again quickly.

Greiner - Leader in Thin-Walled Packaging

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

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

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

  • Thin Wall Injection Moulding with Stack Mould

    Margarine tubs made of polypropylene are produced on our e-speed injection moulding machine with integrated in-mould labelling (IML).

  • Thin Wall Injection Moulding with In-Mould Labelling (IML)

    A double-cavity mould for 1-litre buckets with reduced wall thickness and IML shows what our fastest hybrid packaging machine can do.

  • Production of a Thin-Walled Cartridge

    In the production of cartridges, the e-speed demonstrates uncompromising precision and maximum speed - even with complex components.
