    摘要： An apparatus for fabricating semiconductor packages may include a thickness measurer configured to measure the thickness of a printed circuit board (PCB); mold dies, clamped to the top and the bottom of the PCB, through which a molding compound may be injected; and a pressure controller configured to control a clamp pressure of the mold die in response to the thickness of the PCB. The thickness of the PCB may be measured before molding the PCB, and a clamp pressure corresponding to the measured thickness may be decided. Therefore, it is possible to adjust the thickness variation of a PCB in real time, as they are being produced, to decrease the number of bad packages.

    摘要： By managing a coating material injection time and the like parameters so that they may be controlled within specifically determined ranges, an in-mold coating formation method is provided for manufacturing a molded product coated with a coating layer having a uniform quality in its outside appearance. By continuously and unifyingly managing a mold opening amount and a mold closing force, an in-mold coating formation method and an in-mold coating formation apparatus are provided which are so formed that, if the control of a mold closing force and the control of a mold opening amount are continuously changed and at the same time a high precision and a high response are maintained, it is possible to enlarge a selectable range for selecting a molding condition, thereby producing an integrally formed molded product having an excellent outside appearance and whose coating layer has a high adhesion strength. Further, there are provided a mold having a specifically formed auxiliary cavity and an in-mold coating formation method which employs said mold, so that it is possible to prevent a coating material from leaking out of the mold, thereby shortening the molding formation cycle, and making it possible to manufacture a molded product having a stabilized quality. Moreover, by controlling an internal pressure in the mold cavity under a predetermined condition after the injection of the coating material, there is provided a further in-mold coating formation method which makes it possible to obtain an integrally formed molded product whose coating layer has a sufficient strength with the molded product, without having to use a special coating material and a special resin to be used for molding. In addition, by using a mold having a specifically shaped sub-cavity, there is provided a still further in-mold coating formation method which can keep mold temperature at a relatively low value, cause the coating material to cure at a predetermined temperature and within a predetermined time period, thereby shortening the molding formation cycle, improving the productivity, improving the physical properties of a coating layer, thus obtaining a good molded product.

    摘要： A molding machine in which a load cell unit is mounted on an end portion of one of a plurality of connecting bars elastically deformable (extensionally deformable) due to a load (tensile load) during the operation of molding. At least partially any connecting bar where the load cell unit is not mounted, that is, any connecting bar other than the predetermined connecting bar where the load cell unit is mounted, includes a portion whose diameter is made a predetermined distance smaller than a diameter of the predetermined connecting bar where the load cell unit is mounted. Thus, the quantities of deformation can be equalized all over the connecting bars without using any dummy load cell unit.

    摘要： A clamping apparatus is operable in a closure position detection mode for detecting closure of a mold on the basis of a change in a physical quantity because of closure of the mold, detecting a position of a crosshead of a toggle mechanism at the time of detection of the closure, and obtaining a closure position of a movable platen at the time of the closure from the detected position of the crosshead. The apparatus is previously operated in the closure position detection mode to store, as a reference value, the closure position at which a target mold clamping force is obtained. In the production operation, the apparatus is operated in the closure position detection mode to obtain an actual closure position (detection value). The mold clamping force is corrected on the basis of a deviation of the detection value from the reference value.
