PURPOSE:To prevent a transfer foil of an untransfer film from producing wrinkles by using an apparatus wherein a transfer film having a transfer is carried to a position facing to a cavity and is fixed there and after the transfer foil is transferred on an injection-molded molding, a cutter...
In order to prevent mold deformation or burst mode (especially in the position of the injection port), which requires a strict control of pressure. Injection equipment for the RTM Light process is usually equipped with a pressure feedback device that controls the pressure as a closed loop. RTM...
The heating device 10 is positioned at a specified position by detecting the position by means of a sensor and a transfer layer 20 corresponding to a part necessary to be heated of the transfer sheet 9 is heated and softened. The heating device 10 is then moved downward out of the mold ...

Systems and methods for operating an injection molding machine A method of operating an injection molding machine includes translating a movable platen from a closed position to a part transfer position by overshooting the transfer position in an opening direction away from a stationary platen to an....
Fig. 7-30depicts a schematic drawing of the resin transfer molding set-up. The resin is melted in a single screw extruder, and stored under pressure in a hydraulic accumulator. The accumulator is instrumented for position, and pressure, allowing for accurate control of the parameters, volume, ...
Through-glass fabrication of μ-hole arrays should be accomplished with accurate position and uniform hole size for reliable μVAST. Figure 2a presents a schematic diagram of the LIE procedure to make 20 μm-sized μ-hole arrays with an aspect ratio of 5:1 on a glass substrate. A Femtose...
