INJECTION MOLDING

280ton injection molding machine with robotics,
Brand: Woojin
Year: 2022

Great, you’re describing a 280-ton injection molding machine with robotics by Woojin, year 2022. Here’s a concise overview to help you assess or specify the model, typical capabilities, and a checklist for verification or procurement.

Quick profile

• Brand: Woojin
• Model class: 280-ton horizontal injection molding machine (likely two-platen or toggle/crank design depending on exact line)
• Year: 2022
• Automation: Integrated robotics option (pick-and-place robot, typically inline with part removal, post-mold operations, or secondary assembly)
• Common configurations:
  • Clamp force: 280 tons
  • Shot size: varies by resin; typically ~115–230 g for standard polymers (PP, PS, PET, ABS, PC blends). Exact shot size depends on mold design and screw diameter. Robot options: Cartesian or Articulated robots, part grasping styles, servo-controlled or servo-driven axes, end-of-arm tooling (EOAT) tailored to part geometry.

What to verify / questions to answer

1. Model and tooling specifics:
   • Exact model number (Woojin line often uses abbreviations like WJ-280, SLR-…; confirm from nameplate or model tag).
   • Screw diameter and L/D ratio (affects shot size and plasticizing capacity).
   • Mold protection and safety features (guarding, interlocks, safe operating procedures).
2. Robot details:
   • Robot type and reach (e.g., Cartesian vs. 6-axis articulated).
   • Payload capacity and speed (gripper open/close times, cycle time impact).
   • End-of-arm tooling (EOAT) compatibility and current tooling in use.
   • Integration with machine control (ISO 13849 safety, PLC/HMI compatibility).
3. Performance and specifications:
   • Maximum injection pressure and backpressure settings.
   • Injection speed and cure/dwell times.
   • Cooling channel options and cycle time targets for your typical parts.
   • Power requirements and hydraulic or electric drive specifics (all-electric, hydraulic, or hybrid).
4. Mold and process considerations:
   • Typical minimum/maximum shot size for your target resin.
   • Nozzle temperature control and platen size, stroke, and tie-bar spacing.
   • Mold clamping force distribution and parallelism checks.
5. Maintenance and service:
   • Availability of Woojin parts and service network in your region.
   • Maintenance plan for both the machine and the robot (lubrication, filter changes, servo kinestics).
   • Firmware/software version on the control system and robot controller.
6. Electrical & controls:
   • Control system brand/version (e.g., Woojin CH series, or third-party CNC/HMI).
   • Communication interfaces (Ethernet/IP, Profinet, EtherCAT) for integration with factory PLC/robotics.
   • Safety features: light curtains, pressure safety, emergency stops, reset procedures.
7. Automation integration:
   • Sensor integration for part detection, stack lights, part quality feedback.
   • Data logging capabilities (cycle time, clamp force, shot size, robot cycle times) for OEE/6S.

Typical performance targets (illustrative)

• Cycle time: Depending on part complexity, gate freeze, and robot handling, a 280-ton machine with robot might target cycle times in the range of 15–45 seconds for typical mid-size parts.
• Utilization: Automated part removal can increase line throughput by 20–40% compared to manual handling, depending on part geometry and robot capability.
• Quality consistency: Reproducible shot size and consistent sealing due to precise servo/hydraulic control and robot repeatability.

Next steps

If you’re considering this machine (buying, selling, or upgrading), please share:

• The exact model code or a photo of the nameplate.
• Resin type and typical part dimensions.
• Desired cycle time and production quantity.
• Your region for service/support considerations.

With those details, I can tailor a more precise spec sheet, a checklist for inspection before purchase, and a sample acceptance test plan (IQ/OQ/PQ) for commissioning the Woojin 280-ton with robotics.
