CT-6 Spec Upgrades

Delivering excellent overall productivity for packaging applications, the CT-6 Spec combines increased injection performance with durability improvements required by long-term, fast-cycle molding. These include:

  • Injection speeds have been increased up to 330 mm/s dependent on the injection unit size
  • Enhanced drive cooling and energy management to allow cycle times down to 6s
  • Toggle support rigidity has been improved to ensure reliability at fast cycles
  • Toggle cross-head linearity displacement has been improved to extend the toggle lifespan
  • The SM barrier/mixing screw assembly has been added as standard to improve melt quality at faster cycle times
  • Expanded core matrix to allow for complicated in-mold closing and ejection sequences (optional)
  • Stack mold support via linear bearings (optional)
  • Increased L/D screw and barrel (optional)
  • Increased screw rotation speed (optional)

Bigger molds in smaller machines

Many of the features that have made the SE-EV-A-HD so popular with molders worldwide also provide advantages for packaging applications. For example, several features work together to allow bigger molds to run on smaller machines:

  • Tie bar spacing is the highest among machines of the same class
  • A stronger, more rigid frame construction has increased the allowable mold weight
  • Advanced direct-drive motor technology for clamping with S-Move technology achieves fast clamp open/close speeds up to 56.6 in/s (1438 mm/s), shorter cycle times, and provides smooth, fast clamping
  • Zero-Molding’s Minimum Clamping Molding (MCM) system reduces clamp force requirements
  • For high cavitation applications, Zero-Molding’s Flow Front Control (FFC) system achieves complete and balanced filling across the cavities with reduced injection pressure

Fast, smooth mold open/close

New S-MOVE technology replaces multi-step mold open/close speed settings with an optimized speed pattern that is faster and smoother. This, combined with exceptionally fast clamp open/close speeds up to 56.6 in/s (1438 mm/s), shortens cycle times.

The reduction in vibration due to S-MOVE technology plus increased machine base rigidity also supports take-out robot accuracy at high speeds.

Multi-toggle clamp force control can also be used to reduce cycle times using the high-cycle mode in which filling begins during clamping.

Zero-Molding

Sumitomo (SHI) Demag’s Zero-Molding capabilities include three systems that work together to decrease defects to a rate approaching zero. These systems include:

  • Simple Process Setting (SPS) system which allows easy setup and operations while helping the operator avoid mistakes
  • Flow Front Control (FFC) system for complete filling at lower pressure. In high-speed thin-wall and high-cavitation molding, the ability to balance the fill across the cavities is essential. Zero-Molding’s Flow Front Control (FFC) system achieves complete and balanced filling with reduced injection pressure. The system takes advantage of the energy in the flow front of the resin to complete filling in an even fashion as opposed to forcing material into open areas and flashing areas that were already filled. FFC precisely controls screw position at VP switchover to balance fill speed and pressure across all cavities. Problems associated with overfilling and trapped gases do not occur.
  • Minimum Clamping Molding (MCM) system which reduces clamp force requirements. MCM automatically detects the minimum point at which the mold halves are completely parallel and surface pressure is evenly distributed across the mold faces. Added benefits include avoidance of burn spots and short shots and less trapped gases.

Rapid Return on Investment

Molders will experience a rapid return on investment (ROI) with the SE-EV-A-HD CT-6 due to the application flexibility, the ability to run larger molds on smaller machines, and the overall productivity of the series. Productivity factors contributing to the rapid ROI include:

  • Significant energy savings due to exceptionally energy-efficient, low-inertia motors and low-friction design improvements
  • Reduced water and grease use
  • Faster start-up
  • Reduced scrap
  • Faster cycle times
  • Reduced downtime
  • Quick mold change
  • Minimized preventive maintenance
  • Ability for unmanned and lights out operation

The SE-EV-A-HD is backed by a comprehensive Customer Satisfaction Program with Sumitomo (SHI) Demag’s standard-setting warranty program, worry-free parts, responsive field service and financing availability – plus advantages such as expert processing assistance.

SE50EV-A Demonstrates Complete and Balanced Filling Running an Unbalanced “Family” Mold

SE50EV-A all-electric injection molding demo of an 8-cavity, unbalanced “family” mold for PMMA paper clips. Demonstrates the ability of Zero-Molding’s Flow Front Control (FFC) system to achieve complete and balanced filling with reduced injection pressure. FFC takes advantage of the energy in the flow front of the resin to complete filling in an even fashion, as opposed to forcing material into open areas and flashing areas that were already filled. Filling takes place at a more consistent rate, eliminating problems such as flash, inconsistent part weights and molded-in stress.
