摘要:
An injection-molding system includes an extruding system configured to produce a mixture; a discharging channel communicable with the extruding system and including an outlet configured to discharge the mixture; and molding devices configured to receive the mixture. Each of the molding devices includes a hollow space, and a feeding port communicable with the hollow space and engageable with the outlet. An injection-molding method includes providing an extruding system configured to produce a mixture, a discharging channel including an outlet, and first and second molding devices; engaging the outlet with the first molding device; injecting the mixture into the first molding device; disengaging the outlet from the first molding device; moving the discharging channel away from the first molding device and toward the second molding device; engaging the outlet with the second molding device; injecting the mixture into the second molding device; and disengaging the outlet from the second molding device.
摘要:
Injection molding machine comprising at least one first and one second injection unit having a chamber for injecting a plasticized molding material and a piston for advancing a predetermined amount of plasticized molding material along a first axis from the chamber into a cavity of a mold, the machine including a form tool comprised of at least a first tool portion and a second tool portion, a tool cavity being at least partially disposed in the first tool portion.
摘要:
The present disclosure provides a molding machine and a method of molding a part. The molding machine may include multiple molding systems (e.g., extruders) for pumping molten material into one or more mold cavities. The multiple molding systems may pump the same material or different materials into the one or more mold cavities. The multiple molding systems may be individually and/or collectively controlled. A method of molding a part may include pumping material into one or more mold cavities via multiple molding systems, ceasing pumping material into the one or more mold cavities when one or more pressures associated with the multiple molding systems are achieved, and releasing a molded part from the one or more mold cavities after the one or more pressures are achieved.

Provided is a multi-layer container excellent in delamination resistance and gas barrier property, which can be manufactured without employing any molding method involving a special apparatus, which increases a production cost, and a complicated step. Specifically, the multi-layer container includes a laminate structure of three or more layers having at least a gas barrier layer between an innermost layer and an outermost layer, in which the gas barrier layer in a site formed of the laminate structure has a portion having a thickness 0.01 to 0.9 times as large as the maximum thickness of the gas barrier layer. Further, provided are a mold suitable for manufacturing the multi-layer container, and a manufacturing method for a multi-layer container using the mold.
摘要:
A material handling and mold filling system is provided which directs the flow of molten plastic material from an extruder and allocates the molten material to a plurality of nozzles through the use of independently operated, variable valves. The system therefore provides independent streams of molten plastic material having variable temperatures and flow rates or volumes to particular sections or regions of the mold. This independent temperature or flow of molten plastic material facilitates the complete, rapid and accurate filling of the molds, reducing turbulence and other temperature or flow-related imperfections in the finished components. A multiphase material handling system is also disclosed for expeditious sequential and simultaneous filling and pressing of the mold and extracting the completed component from the system.

摘要:
A method of injection molding at least one part in a single mold having therein at least one cavity, the method comprising providing first and second injection molding devices, using the first injection molding device to inject material into the single mold, and thereafter using the second injection molding device to inject material into the single mold.
摘要:
An injection mold unit is provided for an alternate feed, injection molding of parts of a plasticized material and has first and second plasticizing and injection devices, with a respective bores and a mold comprising a heating channel block and a mold cavity. The heating channel has a first passageway connected to the bore of the first plasticizing and injection device, the first passageway having first and second branches in fluid communication with the mold cavity. The heating channel also has as well as a second passageway connected to the bore of the second plasticizing and injection machine and having first and second branches in fluid communication with the mold cavity. One way valves are located in each of the first and second branches of the first and second passageways. The one way valves respectively located in the first branches of the first and second passageways control a flow of plasticized material in a first direction from one of the plasticizing and injection devices, through the mold cavity, and to the other plasticizing and injection device. The one way valves respectively located in the second branches of the first and second passageways controlling a flow of plasticized material in a second direction from the other plasticizing device, through the mold cavity, and to the one plasticizing and injection device, whereby plasticized material is alternately fed to and through the mold cavity.
