SMC Configurations

Any of these Sheet Molded Composite solutions can be modified to fit your specific requirements.

Basic – Low-cost Upgrade for obsolete equipment or relay logic

Standard – Multiple Part programs with profiling, auxiliary equipment control

Enhanced – Closed loop control, expanded diagnostics and graphics, reporting

Advanced Intelligent Leveling – The Ultimate in SMC press control

BASIC

The basic Oilgear SMC control is designed as low-cost replacement or enhancement to older AC electronic systems and relay logic controls.

The main component in this configuration is the Oilgear EPC programmable amplifier. The din-rail-mounted amplifier provides extended capabilities such as command ramping, programmable calibration, and built-in diagnostics. Optional pressure limiting reduces pump stroke as the command setpoint is reached. This can reduce hydraulic system heat generation and wasted horsepower.

The addition of a micro PLC provides the ability to interface with a position transducer and existing logic for programmable limit switching. A simple operator interface is used to program the pump commands for various parts of the cycle. The micro PLC can completely replace relay logic that is unreliable and difficult to troubleshoot. The basic system can be supplied, pre-wired in an enclosure or as loose components to be installed in an existing box. If the upgrade is replacing an obsolete Oilgear AC system, the required pump conversion parts will be supplied

STANDARD

The standard SMC press control is a PLC based system with an integral operator interface supplied in a NEMA 12 enclosure. The operator interface provides screen editable setup parameters, part program storage, and enhanced diagnostic tools. The PLC extends the capability of the control system to provide profiling, vacuum molding, IMC cycles, and auxiliary equipment control. Some of the system features are:

  • Store and recall multiple part programs
  • Velocity, pressure dwell, and strip profiles
  • Programmable advance/retract speeds
     
  • Comprehensive diagnostics
  • Fault Messaging
  • Fault Logging
  • I/O status monitoring screens
     
  • A Mold Reference cycle allows position switch points to be entered with respect to part thickness
     
  • Closed loop pressure control (hydraulic modifications may be required)
     
  • Option to replace gray scale monitor with color monitor
     
  • Closed loop speed control can be added as an option

 

ENHANCED

The enhanced SMC system adds a powerful PC based information system to the Standard press control. Features of this system include networking, graphics capabilities, production and shift reports, remote off-site press monitoring and on-line drawing viewer. Additional details and several screen shots can be viewed at Windows HMI .

The enhancements also include closed loop velocity profiling for accurate control of the pressing cycle.

 

ADVANCED INTELLIGENT LEVELING

The Oilgear Advanced Leveling System provides the best performance available in SMC press control. Four corner leveling offers advantages that are not available on a non-leveling press.

  • Parallel mold closing with off-center loads
  • Better control for large parts and multiple mold configurations
  • More precise velocity control resulting in better part surface quality
  • Ability to apply surface coatings such as IMC evenly across the part

The leveling system electronics are supplied in a painted, air conditioned NEMA 12 enclosure with power disconnect. The standard configuration includes an Allen-Bradley or Modicon PLC. Other PLC manufacturers can be used when needed.

The Windows HMI is included with the Advanced Leveling Control to provide performance monitoring and part tracking.

Custom remote operator stations, networking, and remote I/O boxes can be supplied.
