  • Patent number: 10160148
    Abstract: A nozzle retention arrangement is provided for an injection molding manifold system, such as a hot runner manifold system. The nozzle retention arrangement couples an injection nozzle to a distribution manifold in a manner that locates the nozzle in its final operating position and applies an initial assembly load to retain the nozzle in position on the manifold to facilitate installation of a manifold system into a manifold plate. The nozzle retention arrangement may provide a compliant load application feature to limit sealing surface pressure between the nozzle and the manifold to prevent surface damage between the components, while also accommodating thermal expansion of the heated components during operation of the system. The nozzle retention arrangement may also provide a load control feature to prevent the machining quality of the nozzle bore in the manifold plate from determining the sealing load between the nozzle and the manifold.

  • Patent number: 10144165
    Abstract: A molding method for the production of articles molded by injecting plastic material into a mold cavity by a plurality of injectors electrically sequentially actuated under an electronic control according to a cycle providing for a step for filling the mold cavity, followed by a step for packing the plastic material in the mold cavity. Each injector, regardless of both its position with respect to the mold cavity and its opening speed, is controlled in at least one of the following control modes: i) partially closing the injector from a maximum open condition to a less opened condition in the filling step, ii) setting the injector in a partially open condition and then opening the injector to a more opened condition, in the packing step.

  • Patent number: 10131079
    Abstract: A side gate nozzle assembly for a hot runner apparatus comprises a disc shaped base body, a probe member, a sealing insulator, and a shape memory alloy washer. The probe member with a probe channel extends from the base body. A molten molding material is received through a melt channel of the nozzle body, and allowed to pass through the probe channel to be transferred to a cavity of a cavity member. The shape memory alloy washer is positioned between the base body and the sealing insulator. The shape memory alloy washer distorts linearly to push the sealing insulator and the probe member according to change in temperature due to transfer of the molten molding material from the melt channel to the cavity member via the probe channel. The distorted shape memory alloy washer prevents leakage of the molten molding material from the melt channel, and the probe channel.

  • Patent number: 10124522
    Abstract: A retaining pin for handling injection molded preforms includes a body including an internal body flow channel, and a plunger coupled to the body and movable relative to the body between advanced and retracted positions. The plunger includes an internal plunger flow channel. The plunger further includes a plunger abutment surface directed away from the body. The plunger is biased toward the advanced position and movable to the retracted position by engagement of the plunger abutment surface with an inner surface of a closed end of a preform when the preform and retaining pin are moved toward each other. The body flow channel and the plunger flow channel are in fluid communication when the plunger is in the retracted position. Fluid communication between the plunger flow channel and the body flow channel is inhibited when the plunger is in the advanced position.

  • Patent number: 10105878
    Abstract: A composite material molding method is provided for forming a composite material. The molding includes disposing carbon fiber in a cavity inside an openable and closable mold, injecting resin into the cavity in a state in which a clamping pressure is exerted on the mold and curing the resin. When a threshold value of the pressure inside the cavity is set to a pressure that is lower than the clamping pressure and the resin is injected into the cavity while exerting an injection pressure that is equal to or greater than the clamping pressure on the resin until the pressure inside the cavity reaches the threshold value. Then, after the pressure inside the cavity has reached the threshold value, the inside of the cavity is suctioned.
