How Does LEGO Sort Bags?

Published in LEGO Packaging 2 mins read

Getting the correct pieces into the bags for a LEGO set involves a careful and precise process focused on filling bags with the right components and verifying accuracy. Based on the provided information, the process primarily describes how sorted parts are put into bags for a specific set and then checked for quality.

The LEGO Bag Filling and Quality Control Process

The method used to ensure that each bag within a LEGO set contains the necessary pieces involves several key steps:

  1. Manual Filling of Hoppers: The process begins with hoppers being manually filled by workers with the parts belonging to a corresponding set. This means that pre-sorted bulk parts for a specific LEGO set are loaded into designated hoppers.
  2. Calibrated Dispensing: After the hoppers are filled, each hopper is then calibrated to distribute the correct number of pieces per bag. This calibration is crucial for accurately portioning the parts for each individual bag within a set.
  3. Precise Weight Checks: As a final quality control measure, each bag is weighed precisely 6 times. This rigorous weighing process is a primary method used to confirm that the correct number and type of pieces are inside, as the weight should fall within a very narrow acceptable range.

This process ensures that the bags included in LEGO sets contain the designated parts accurately, contributing to the building experience for consumers.
