An injection molding system is provided with inspection means for inspecting an insert part before a resin is injected into a mold, inspection data output means for outputting inspection data on the insert part obtained by the inspection means, and inspection data recording means for recording the inspection data on the insert part and physical quantities related to the injection of the resin into the mold in association with the cycle number of the molded article from the injection molding machine. Thus, the cause of bad molded articles, as well as that for a finished product, can be investigated in consideration of the inspection data on the insert part inserted into the mold.

The invention relates to a device for orienting elements, in particular filter elements (F), for fitting injection-molded parts, in particular pipette tips (P), comprising an accommodating container (1a) for accommodating the filter elements (F) as bulk material, a sieve plate (1), which forms the bottom of the accommodating container and which has bores (11) for accommodating individual filter elements (F), a buffer plate (2), which is arranged under the sieve plate (1) and which has bores (2.1) corresponding to the bores of the buffer plate (2) and which is arranged below the buffer plate in such way that the transfer plate can moved in relation to the buffer plate (2).
