In an injection molding system, an insert formed with a cavity or an insert member for molding an insert-molded article is shot by a camera, and the insert or the insert member to be inserted into a mold is identified based on a characteristic of the insert or the insert member shot by the camera and previously stored data on the insert or the insert member.

Apparatus for checking a state of a machine part of a shaping machine, comprising an evaluation unit, at least one power loss sensor for ascertaining a power loss measurement signal which is representative of a power loss in and/or at the machine part, and at least one movement sensor for ascertaining a movement measurement signal which is representative of a movement of the machine part, wherein the evaluation unit is adapted to compute a damage indicator for the machine part from the power loss measurement signal and from the movement measurement signal.

A method for carrying out a cyclical manufacturing process produces parts within a predefined quality tolerance. After at least one process adjustment variable is changed, a quality feature of the parts produced with a changed process adjustment variable is checked against the range of the quality tolerance of the produced parts. A process characteristic variable zone is formed in an automated manner using at least one determined process characteristic variable variant that is process-stable and for which the process adjustment variable produces acceptable parts.

An air ejector of a resin molding device includes air passages, air outlets through which air is injected, movable valves biased by bias members to close the air outlets, accommodation spaces in which the movable valves are movably contained, an air supply path through which air is supplied from an air supply source, and a pressure sensor to detect air pressure. After completing the mold removal, the air is supplied via the air supply path to the air passages at an air pressure smaller than the bias force of the bias members, and the air pressure is detected by the pressure sensor.

An attachment for a washing or rinsing agent bottle. The attachment is made from a main component and at least one auxiliary component in a multicomponent injection casting method, wherein a seal element is molded using the auxiliary component. The main component or the auxiliary component has a marker which causes a contrast between the auxiliary component and the main component under UV light or IR light. The invention also relates to a method for producing such an attachment.

The present disclosure relates to a system and method for monitoring an injection molding process which may calculate injection time and packing time by attaching an acceleration sensor to an injection molding mold with bolts and measuring an amplitude change of a vibration signal of a mold during injection molding, detect mold closing and opening signals of the mold using a magnetic hall sensor, and monitor the injection molding process by measuring cycle time and cooling time, thereby simplifying installation and maintenance and reducing installation costs.
