Provided is a double injection molding system capable of continuously and automatically manufacturing four molded products for a vehicle at a time, the double injection molding system including: a first molding device which molds the openable plates of the molded products for a vehicle through injection of plastic; a second molding device which receives the openable plates and molds the sealing portions through injection of rubber around the openable plates to finish the molded products; and a transport device which takes out the openable plates formed by the molding device and transports the openable plates, to the second molding device, so that the double injection molding process of the openable plates and the sealing portions is automated to secure product reliability and to improve productivity.

A method for manufacturing an injection molded container includes operating an injection molding apparatus to inject one or more polymeric materials into a mold cavity to form a container. The container includes an energy director ring protruding from an inside surface of the container and extending circumferentially along the inside surface. The method includes welding a filter onto the inside surface by applying a welding force to the inside surface. The energy director ring causes the welding force to be concentrated at a location of the energy director ring, thereby forming a circumferential weld that secures the filter to the inside surface the location of the energy director ring.

An injection molding apparatus includes a first upstream mold having a first gate opening into which a first molding material flows, a second upstream mold having a second gate opening into which a second molding material flows, a first injection unit injecting the first material through the first gate opening, a second injection unit injecting the second material through the second gate opening, and a downstream mold clampable with each of the first and second upstream molds. The second material is injected by the second injection unit after the first material is injected by the first injection unit. The second gate opening is separated further from the downstream mold than the first gate opening, and a volume of a second cavity partitioned by the second upstream mold and the downstream mold is larger than that of a first cavity partitioned by the first upstream mold and the downstream mold.

Method for manufacturing plastic preforms (10) by injection moulding, consisting of sub-preforms (11, 12) injected at the same time, wherein (1) the injection mould (3) containing the injected composite preform (10) and secondary sub-preform (12) is 1 st closed, and a gripper (4) provided with a set of receiving members (16) is set in a standby position (A) aside from the mould (3); in a 2nd step (2) the mould (3) is opened, wherein each primary core (33) bears an injected composite preform (10), and the secondary core (33) a secondary inner preform (12); the gripper (4) is then driven (3) in motion between the standby position (A) and a take-over position (B), wherein the injected preforms (10, 12) are cooled and taken over from the core side (31) by the gripper (4) by means of suction means (6); wherein the gripper (4) is further moved (4) into a further operating position (C), in which it places the received secondary inner preforms (12) onto the respective primary cores (33) and continues to hold said preforms (11), with formation of integrated preforms (10) which are expelled to a discharge unit.

An injection mold for producing a double walled drinking vessel includes first and second mold portions. The first mold portion forms a first and second cavities corresponding to the outer shape of the outer container and the outer shape of the inner container, respectively. The first and second cavities are located concentrically with respect to a central axis. An index plate is rotatable and axially movable along the central axis relative to the first mold portion. The index plate includes a first core and a second core. The first cavity has a first cavity injection gate for injecting mold material into the first cavity for forming the outer container. The second cavity has a second cavity injection gate for injecting mold material into the second cavity for forming the inner container. The first cavity has a further injection gate for injecting joint material for joining the outer and inner containers.

Disclosed is an injection molding process control method of a multi-color injection molding machine, and its automated process setting includes a mold-opening ending process setting and a mold-closing ending process setting. The mold-opening ending process setting includes a multiple of action options sequentially carried out after a setting is selected from the mold-opening ending automated process option, and the mold-closing ending process setting is a setting selected from the mold-closing ending automated process option according to each switching action, so that the multi-color injection molding machine can use a page of the automated process setting together with the desired action option to click and select a setting according to different injection molding objects or molds, so as to complete the correction and setting of the injection stroke quickly and improve the operational efficiency of the injection molding.
