The state of the art of full-electric injection molding: real case study in the plastics sector

THE TRANSITION TO ELECTRIC IS NOW THE STANDARD FOR HIGH-PRECISION PRODUCTION AND FOR VOLUMES REQUIRING RAPID CYCLES AND LOW ENERGY COSTS

The demands of modern production technology are constantly increasing, particularly regarding process innovation, energy efficiency, and, last but not least, respect for the environment.

The adoption of completely electric and mechanical drives for mold movement and all axes in an injection molding press offers significant advantages over traditional hydraulic systems.

Traditional screw jacks (both trapezoidal screw and ball screw) have reached their limits in the most demanding industrial applications. Often, they no longer offer the necessary characteristics of dynamics, force, and precision required by complex duty cycles.

In contrast, ATLANTA servoactuators, thanks to their unique combination of advanced features, are the state of the art and are employed with great success precisely in these high-performance applications.

ATLANTA servoactuators innovate the process and redefine application limits

The advantages of movements managed by electric servo motors and ball screws instead of hydraulic cylinders and pumps have already been analyzed on the SERVOACTUATORS VS. HYDRAULICS page
In summary, the advantages are:

  • energy efficiency
  • control and precision
  • maintenance reduced to a minimum
  • fast infrastructure
  • simplified synchronization

Here, we will identify the benefits of using ATLANTA servoactuators in the thermoplastic injection molding process. In particular, a crucial phase of the injection molding process is part ejection. Conventional systems often rely on hydraulic drives, which are powerful but also energy-intensive and require a lot of maintenance.

The ATLANTA system replaces conventional hydraulics with a drive mechanism designed ad hoc for Spline-Konstruktionen’s molds, to which the control systems engineered by Plexpert have been applied.

The specific advantages of the ATLANTA solution

In addition to the general benefits of the full-electric solution, in mold automation you get:

  • high dynamics and precise positioning – the solution allows for rapid movements and precise positioning for accurate processes
  • multiple positions in the mechanism – it is possible to flexibly and precisely control multiple positions, which facilitates mold design
  • repeatability: the system provides stable performance, regardless of external influences, and guarantees high process reliability
  • reliable holding of the final position – minimizing the risk of damage even in the event of power outages
