摘要:
The invention relates to a method and a device for monitoring and/or optimizing flow processes, in particular injection molding processes. Vibrations caused by a flow of a material are detected and analyzed, wherein a vibration spectrum is detected at different times or in a (virtually) continuous manner and subjected to a multidimensional analysis.

The invention relates to a control method for controlling the back pressure in an injection molding machine comprising a first motor that axially displaces a worm and comprising a second motor that turns said worm, whereby both motors act upon a common shaft. In order to control the back pressure, the invention provides that a velocity set value vR for controlling the second motor (5) is furnished as a rotational speed specified set value to a control circuit that serves to control the velocity or rotational speed of the first motor (4). The back pressure is thus controlled according to a pressure difference resulting from the difference in rotational speeds of both motors.

The present disclosure provides a method of manufacturing a metal shell of a communication equipment and a metal shell of a communication equipment thus obtained, the method includes steps of: 1) performing a first injection molding on a non-slit region of an inner surface of a metal substrate; 2) forming at least one slit on a slit region of the inner surface of the metal substrate; and 3) performing a second injection molding on the slit region of the inner surface of the metal substrate.
摘要:
A tool (100) for manufacturing a component part from a flowable base material, wherein the tool (100) comprises a processing chamber (102) into which the flowable base material is introducible for manufacturing the component part, an acoustic sensor (104) configured for sensing an acoustic signal originating from the tool (100), particularly from the processing chamber (102), and being indicative of an interaction between the flowable base material and the tool (100), particularly the processing chamber (102), during the manufacturing, wherein the acoustic sensor (104) comprises a movable actuator (110), and a control unit (200) configured for controlling and/or documenting the manufacturing in the processing chamber (102) based on the sensed acoustic signal.
摘要:
A monitor for maintaining a mold cycle count with an actuator sending a count signal to a processor following a mold operation. The monitor further includes a timer having an active mode and a sleep mode. The processor generates an average cycle time and an activity percentage of the mold taking into account active and sleep periods of the mold.
