Plastic Injection. On-the-fly weighing. Without modifying the robot.
How we eliminated the weighing bottleneck in plastic injection lines — without touching the robot.

In plastic injection,
every gram counts.

be verified
in most factories
Traditional checks require stopping the robot, placing the part on an external scale and resuming — a bottleneck most factories simply ignore. Defects only surface at final inspection, or worse, at the customer.
Savings on raw material can pay for the system
Every overweight part wastes polymer. Every undetected void wastes a full cycle. With 100% weight coverage, excess material is cut and scrap is detected before it accumulates — enabling ROI in months, not years.
codebox.pt/autoscale Mounted between
the robot head
and the gripper.
AutoScale sits between the robot arm and the gripper that extracts the part from the mould. Weighing happens during the extraction movement itself — before the injection cycle ends.
No extra station. No detour. No additional time.
codebox.pt/autoscale Weight is quality.
Measured before
the cycle ends.
AutoScale weighs every part during extraction — using a patented differential principle to cancel robot vibrations. But weight is just the beginning.
By correlating weight with injection parameters — pressure, temperature, cycle time — the software anticipates problems before they produce NOK parts, not after.
OK / NOK decision before the injection cycle closes
Pressure, temperature and cycle time tracked continuously
Deviation detected early — operator warned before defects occur
Optional thermal module — surface temperature of the part analysed at extraction to detect injection defects.
