摘要:
A material characterization system and method for quantifying the characteristics of a flowing thermoplastic material is presented. The system comprises a tool comprising first and second tool halves, a plurality of flowing material characterization channels, and a feed runner. The tool is at a temperature that causes phase changes from fluid to solid in at least a portion of the characterized material and enables solidification of the material in the flowing material characterization channels. The feed runner is connectable to a single flowing material characterization channel. The tool is adjustable to disconnect the feed runner from one flowing material characterization channel and connect it to different flowing material characterization channels. A sensor quantifies the characteristics of the material under different flow conditions. The method comprises measuring the material characteristics as it flows through the flowing material characterization channel at multiple flow rates and repeating measurements for different flowing material characterization channels.

Provided is a molding machine system enabling a free setting of execution timings of respective steps in a molding cycle of heating of a mold, injection and pressure holding of a molding material, cooling of the mold, etc. The molding machine system repeating a series of molding cycle comprises three temperature sensors arranged at predetermined places of a mold, a change-over valve unit having a heat medium channel by which heating medium from a heating unit, cooling medium from a cooling unit and pressurized air are changed over to be supplied into and recovered from the mold and a molding control means, provided on the change-over valve unit, having a temperature judging program judging respective detected temperatures of the three temperature sensors to give a judgement result and a timer to give a time set signal. A molding operation control is carried out by combining the judgement result with the time set signal and enables an arbitrary supply control of the heating medium, cooling medium and pressurized air to be supplied into the mold and an arbitrary supply control of the molding material to be supplied into the mold.
摘要:
A method of molding a thermosetting resin, in particular of the epoxy resin type, in which a first mold is filled with the resin while causing the temperature of the resin to vary in application of a first temperature program, without exceeding the Tg of the resin. After the first mold has been filled, the resin is put under pressure while causing the temperature of the resin to vary in application of a second temperature program, without exceeding Tg, and a drop in the pressure exerted by the resin on the mold is detected with the instant at which this pressure presents a break of slope being identified as the instant t1. A second mold is filled with the thermosetting resin in application of the first temperature program. After the second mold has been filled, the resin is put under pressure in application of the second temperature program until an instant t2 close to t1. As from t2, the temperature of the resin is increased to exceed Tg.

A control system and a control method of manufacturing injection molding products are provided. The control system includes an injection molding machine, an information input interface, a computing server and a data conversion device. At first, product information is inputted through the information input interface. The product information is transmitted to the computing server, and then the computing server determines injection molding parameters according to the product information. The injection molding parameters are transmitted to the information input interface. After data conversion through the data conversion device, the injection molding machine is controlled to manufacture the injection molding products according to the converted injection molding parameters.
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.
