Injection Molding Robot Automation — MetalPlast Case Study

Triton Engineering — with Sweden Engineering Partner (SE-EP) — integrated a client-owned six-axis robot with an injection molding press at MetalPlast. Automated plate pickup, two-plate stacking and conveyor indexing for unattended production.

THE CHALLENGE

Side-Entry Access, EUROMAP Sync, and Reliable Vacuum Pickup

MetalPlast operates a plastic injection molding press producing perforated plates around 500×500 mm. The existing manual pickup workflow created a bottleneck at the press and ruled out continuous unattended operation. SE-EP, the Swedish integration partner on this project, brought in Triton Engineering to design and commission the automation cell around the client-owned six-axis robot.

Restricted overhead clearance ruled out a top-entry approach — the robot had to enter and exit the open mold area from the side on every cycle.
Cycle synchronization with the press demanded an industrial EUROMAP 12 interface — generic I/O wiring would not have satisfied operational safety or repeatability.
Perforated plates require a vacuum gripper with redundant zones — a single vacuum loss must not drop a part during high-speed extraction.
Two plates per cycle had to be reliably stacked and indexed on the downstream conveyor without operator intervention.

THE SOLUTION

Side-Entry Vacuum EOAT and EUROMAP 12 Synchronization

Triton delivered a two-zone vacuum end-of-arm tool, the EUROMAP 12 interface cable, complete robot programming and on-site commissioning. The result: hands-off pickup-and-stack cycles, driven by the press's own mold-open signal.

Two-Zone Vacuum EOAT: Custom end-of-arm tool with two independently controlled vacuum zones — each with its own ejector, valves, and confirmation sensing, so plates with holes are held securely throughout extraction.
EUROMAP 12 Interface: Standardized industrial cable links the robot to the injection press for mold-open and part-out handshake — no custom electronics or proprietary middleware in the signal path.
Side-Entry Trajectories: Robot motion paths were programmed to enter and exit the mold area through the narrow lateral opening with minimum dwell — preserving press takt time.
Pickup Confirmation Logic: Vacuum is verified at both zones before the robot retracts from the mold area — if confirmation fails, the cycle holds and the operator is alerted, with no risk of dropped parts inside the tool.
Two-Plate Stacking Sequence: Each cycle places two plates onto an indexing conveyor that advances one position downstream — stable, hands-off material flow toward the next process step.
On-Site Commissioning: Triton's engineering team commissioned the cell at MetalPlast, ran a live production batch, tuned vacuum and motion parameters, and trained the press operators.

PRODUCTS USED

Equipment & Systems

Two-zone vacuum EOAT: Ejectors, suction cups, valves, manifolds, hoses, fittings, gauges and the aluminum mounting frame — engineered for ~500×500 mm perforated plates.
EUROMAP 12 ↔ EUROMAP 67 cable: 5 m industrial interface cable connecting the client robot to the injection molding press for synchronized cycle operation.
Robot programming: Side-entry trajectories, pickup and stacking sequences, vacuum-zone control logic, and safety-zone definitions on the client-owned six-axis robot.
EUROMAP handshake & sequences: Mold-open, part-out and ready signals coordinated between robot and press using standardized industrial messaging.
On-site commissioning (SAT): Live production run on the client floor, parameter tuning, operator training, and signed acceptance protocol.

RESULTS

MetalPlast's injection press now runs an automated pickup-and-stack cycle directly from the open mold. Operator workload at the press dropped to monitoring only, takt time is repeatable, and the line is ready for continuous unattended shifts.
