A technique for managing a shear heating value of a molding material is provided. A control device of an injection molding machine individually controls outputs of a plurality of heating units for a plurality of zones, respectively, into which a cylinder is divided in a flow direction of a molding material. The control device acquires the output of the heating unit provided in a predetermined zone both in a steady state in which an operation of a screw provided inside the cylinder is stopped and at a time of molding at which the operation of the screw is performed, and calculates a difference in output of the heating unit provided in the predetermined zone between at a time of molding and in the steady state.

A hot runner process controller configured to monitor the status and operation of a hot runner system to autonomously generate information to improve the quality of injection molding process of a hot runner system having an inlet nozzle, one or more manifolds and one or more nozzles with actuator or without actuator, and one or more heating elements, the hot runner process controller is self-operating, and independent from the injection molding machine, includes: one or more sensors located on, in or at the hot runner system to detect the status and/or the operation of the hot runner system, and a processing unit and a memory. The processing unit is connected to the one or more sensors, wherein the memory stores data and program codes. The processing unit is configured to load and execute the program code to compare sensor information with the stored data and to determine if the hot runner system is in an operable status, and in case the hot runner system is in an operable status, configured to generate status information to activate the one or more heating elements and/or the one or more actuators enabling a production operation of the injection molding machine. In case the hot runner system is not in an operable status, configured to generate status information to deactivate the one or more heating elements and/or close or deactivate the one or more actuators disabling a production operation of the injection molding machine.

A detector attachment unit is provided that has at least two or more mounting hole sections for which the temperature detector is detachably attached to the outer surface of the heating cylinder and the temperature detector can be attached at different selected positions in at least the axial direction of the heating cylinder. The temperature control system includes an inner wall face temperature conversion function unit to perform conversion processing to convert the heating temperature detected by the temperature detector to the inner wall face temperature of the heating cylinder, and an inner wall face temperature display function unit to perform at least display processing on the inner wall face temperature obtained by this inner wall face temperature conversion function unit.

Polycarbonate-based compositions containing polyether carbonate polyol are described. The compositions have an elevated transmittance in the VIS range as a result of the additive and further advantageous properties, for instance improved demolding characteristics. Even small amounts have a significant impact.

An LWRT plus fabric injection overmolding process for the direct injection molding of thermoplastic features onto the B-side of a formed, finished Light Weight Reinforced Thermoplastic panel. The panel having an A-side finish cloth, non-woven, TPO, Vinyl or similar material placed into the injection molding press and injection molding tool, and then the features are injection molded onto the panel without damaging the A-side finish.

An injection molding apparatus including a mold, an injection device and at least one sensor is provided. The mold has a mold cavity. The injection device is adapted to inject a material into the mold cavity such that the material is formed into a forming article. The at least one sensor is disposed on the mold and adapted to sense at least one of a temperature and a pressure in the mold cavity. The at least one sensor is located at an inner surface of the mold cavity and corresponds to a non-appearance surface of the forming article. In addition, an injection molding method is also provided.

An injection molding system includes a first unit that has a first injection molding machine configured to inject a first molding material into a first cavity partitioned by a first fixed mold and a movable mold, a second unit that includes a second injection molding machine configured to inject a second molding material into a second cavity partitioned by a second fixed mold and the movable mold, and a movement mechanism configured to, after the first molding material is injected into the first cavity, move the movable mold filled with the first molding material from the first injection molding machine to the second injection molding machine.

A molded resin component includes a first surface on which a convex portion is formed, and a second surface opposite to the first surface. The convex portion includes a molding mark formed by a valve pin of a manufacturing apparatus that manufactured the molded resin component. A shape of at least a portion of a leading-end surface of the valve pin is not transferred into the molding mark.

Embodiments relate to apparatus for manufacturing a carbon block filter and a method for manufacturing a carbon block filter. The apparatus for manufacturing a carbon block filter according to an embodiment may include a mold having an inner space, a heater coupled to the mold to heat the mold, a material injection unit injecting a material to the mold heated by the heater, a material pressing unit pressing the material, and a filter separation unit separating a thermally treated filter from the mold heated by the heater.

Provided is an injection molding support system and method that can support searching for suitable materials. This injection molding support system 1 comprises: a process 35 of acquiring a production result using a combination of a mold and a predetermined material and material information on a predetermined material; a process 36 of acquiring the production result, the material information on a predetermined material, and material information on a plurality of previously acquired materials, and selecting at least one candidate material from among the plurality of materials on the basis of the acquired information; a process 43 of creating a correction molding condition for injection molding using a combination of the selected candidate material and the mold; and a process 34 of providing, to a user, the created correction molding condition and the output candidate material.
