A sensor lever for technical applications in motor vehicles. In its basic configuration, this sensor lever has a base lever arm and a sensor lever arm for installing at least one sensor and/or a tactile element. According to the invention, the sensor lever arm is aligned in the desired position with respect to base lever arm in the course of production.

Provided is an injection device and an injection control method which are capable of preventing a drooping phenomenon from an injection nozzle even during high cycle molding, and capable of appropriately plasticizing and molding a resin having poor thermal stability. An injection device (10) of the disclosure includes: an injection cylinder (30) which accumulates a molding material and has an injection nozzle (33) at the front; an injection plunger (31) which is moved backward in the injection cylinder (30); an injection plunger driving device (50, 150) which moves the injection plunger (31) backward; and an injection controller (60, 160). The injection controller (60, 160) retreats the injection plunger (31) by the injection plunger driving device (50, 150) to perform metering in a plastication metering step of metering the molding material supplied into the injection cylinder (30).

A control device for a handling device includes a storage medium, a processing unit, an output for outputting signals, and an input for receiving signals from the handling device. A waiting phase is conducted before an actuation of an end-of-arm tool mounted to an end-of-arm of a handling arm. The signals received by the input represent a dynamic parameter of the end-of-arm and a threshold value corresponds to a specific dynamic parameter of the end-of-arm stored in the storage medium. The signals received by the input can be compared with the threshold value by a comparison unit of the control device, and an end of the waiting phase can be determined when reaching the threshold value. Depending on a curve of the dynamic parameter, the threshold value can be determined and the end of the waiting phase can be determined when reaching the threshold value.

A method for controlling an injection cycle of an injection molding machine incudes advancing an injection screw axially forward toward an injection nozzle from a shot-size position to an injection position to inject melt from a shot chamber into a hot runner of a mold and from the hot runner to fill cavities of the mold. Then the injection screw is retracted away from the nozzle, from the injection position to a decompression position axially rearward of the shot-size position, to relieve melt pressure in the hot runner. Then the screw is advanced toward the nozzle from the decompression position to an intermediate position axially intermediate the injection position and the shot-size position. The method then includes rotating the screw to re-fill the shot chamber with melt and urge the screw to retract from the intermediate position to the shot-size position.
