摘要:
A method for evaluating rubber is provided which can evaluate the degree of crosslinking of a crosslinked rubber product within a short period of time without performing any specific treatment. In the above method, the amount of energy shift of the peak (such as the peak of C12p3/2 of chlorinated butyl rubber) of a constituent element of the rubber is measured by photoelectron spectroscopy, and the degree of crosslinking of the rubber is evaluated from the amount of energy shift. In addition, a method for manufacturing a rubber product is also provided which includes the steps of measuring the amount of energy shift of the peak of a constituent element of the rubber product by a photoelectron spectrometer which is installed in a manufacturing line and then feeding back measurement result to adjust heat molding conditions so as to obtain a desired degree of crosslinking.

摘要:
Methods of monitoring and controlling a molding process using a sensed change in strain provided by a strain gauge are provided. A target strain profile is created for a molding process of a molding apparatus. An upper and lower deviation limit from the target strain profile for the molding process is provided. If a sensed change in strain exceeds a deviation limit, an alarm is activated.
摘要:
A plant for the continuous production of preforms for plastic containers using at least polyester recyclate for the filling of foodstuffs, having at least one melt-producing upstream plant section, at least one preform producing injection molding plant section, and a plant control system, where at least the melt-producing upstream plant section and the injection molding plant section are interlocked at an interface to form a plant block. For the derivation of process alteration strategies and/or preform qualifying strategies, an inline measurement station including an evaluating device is provided at the interface for at least one quality parameter of the melt measured in the process flow.
摘要:
A nozzle has a valve pin for controlling flow of molding material through a nozzle melt passage. An actuator has a stationary part and a movable part. The actuator further has an extending rod connected to the movable part thereof and a block connected to the rod, the block being movable with the moveable part of the actuator. A pivoting linkage element is rotatably connected to the block of the actuator and is connected to the valve pin of the nozzle. The pivoting linkage element moves the valve pin in response to movement of the movable part of the actuator. A bracket is connected to the stationary part of the actuator. Two sensors are connected to the bracket for detecting different positions of the block. The sensors may be air proximity sensors.
摘要:
A method for controlling and/or monitoring a production plant for producing a multiplicity of articles, wherein the production plant has a machine tool; a machine tool part which interacts with the machine tool in order to produce an article; an RFID transponder connected to the machine tool part; two RFID reading devices which are arranged at a distance from one another and from the machine tool; and a control device which is connected to the RFID reading devices via data lines. The method includes determining a first location of the machine tool part at a first time with the first RFID reading device and/or with the second RFID reading device; and determining a second location of the machine tool part at a second time, which temporally follows the first time, with the first RFID reading device and/or with the second RFID reading device; and outputting at least one control signal with the control device on the basis of the first location and the second location.

摘要:
A system and method for manufacturing composite material components having substantially uniform properties comprising means to control the metering of constituent composite material components during manufacture. The resulting composite material components may, for example, be used in the construction of decking systems, railing, porches, fences, stairs, or other similar or suitable applications that may benefit from aesthetically pleasing appearances.
