Reliable check weighing despite disruptive influences

Minebea Intec puts the customer first. With this in mind, the global provider of industrial weighing and inspection solutions develops innovative solutions, tailored for differing requirements across a wide range of sectors. The example of Playmobil manufacturer geobra Brandstätter Stiftung & Co. KG perfectly illustrates how the technology experts ensure reliable check weighing despite disruptive influences in injection moulding.

Production-related disruptive influences are present in almost all industrial environments. In injection moulding, for example, temperature fluctuations and electrostatic charge are constant companions when processing plastics but these can affect the subsequent weighing process. Electrostatic charge can be caused by transferring plastic components from one container to another, for example, which makes it more difficult to obtain precise and repeatable measurement results in the downstream process steps. Processing melted plastic causes temperatures to rise. Ventilation can help to compensate for temperature fluctuations but does create draughts, which can also affect the weighing result. For Playmobil manufacturer geobra Brandstätter Stiftung & Co. KG, the check weighing of packaged small parts always represents a challenge. The lack of precision when weighing small toy parts had previously been compensated for by over filling to be on the safe side.
