G&W AM – Control modules

Maximator Control Modules are suitable for series production with high-pressure nitrogen supply or high-pressure carbon dioxide supply, at a pressure of 500 bar (7,250 psi). The control modules regulate the injection pressure in the GID process.

Application

The Control Module is a self-contained functional unit for pressure-controlled fluid injection in the GIT process, and can be adapted to all injection molding machines, independent of the type and manufacturer.

After receipt of the start signal from the injection molding machine, the fluid injection is implemented. The pressure control is realized exactly by means of hydraulically-operated, 3/3-way proportional valves from Maximator. As a result, both switchover markings and melt standstills are effectively avoided.

Thanks to the intelligent software, production parameters can be flexibly adapted to individual requirements. With this, rising as well as falling ramps can be freely adjusted with up to 10 individual pressure levels. This guarantees perfect interior surface quality in the gas chanel.

RM/500/2(4)/N2

Control Module for nitrogen up to 500 bar

The RM/500/2(4)/N2 Control Module is designed for the exact injection of nitrogen in gas assisted molding processes. Depending on the design, the Control Module is equipped either with 2 or 4 highly-dynamic, Maximator 3/3-way proportional valves for the pressure control, and can optionally supply up to two injection molding machines.

  • Very high reproducibility
  • Self-contained functional unit
  • Available with two or four 3/3-way proportional pressure-control valves
  • Graphic representation of curve progressions
  • Pressure/Time profile freely programmable
  • Compatible with all injection molding machines
  • EUROMAP 62 interface

RM/500/2(4)/CO2

Control Module for liquid carbon dioxide up to 500 bar

The RM/500/2(4)/CO2 Control Module is designed for the exact injection of carbon dioxide in the new CO2 GIT process.

Depending on the design, the Control Module is equipped either with 2 or 4 highly-dynamic, Maximator 3/3-way proportional valves for pressure control.

As a result of the integrated 2.5 liter / 500 bar piston accumulator, a continuous volume flow is ensured for a stable process with high-quality results.

  • CO2 compatible 3/3-way proportional valve technology
  • Optimized cross sections for the highest flow capacities
  • Integrated 2.5 liter / 500 bar piston accumulator for continuous volume flow

Control Modules RM350 Series

Control Module for Nitrogen up to 350 bar, equipped with a gas booster and core control packs as an option.

The MAXIMATOR RM350 Series Control Modules are precision Gas Controllers for Assisted Injection Molding up to 350 bar. The Control Modules are equipped with 2 or 4 gas control valves. Two interfaces allow the RM 500 Series Gas Control Modules to work with 1 or 2 injection molding machines at the same time.

Because of the modular design of this Control Modules, the RM350 Series can be equipped with an air driven Maximator gas booster as an option. This allows the nitrogen supply from standard nitrogen gas bottles.

Furthermore, the Control Modules of the RM350 Series can be equipped with core control packs including controles for hydraulic cores to operate overspill pins or valve gates. This option is available as signals only or with integrated 2 or 4 valve hydraulic power pack.

  • RM350 basic unit has 2 or 4 valves and operates with high pressure (up to 350 Bar, 5000 psi) nitrogen gas supply
  • RM350B includes air driven Maximator high pressure gas booster
  • Core control packs include controls for hydraulic cores to operate overspill pins or valve gates. Options for signals only, or with integrated 4 or 8 valve hydraulic power pack.
