An injection molding system includes an extruding system, a discharging channel, a molding device including a first and second mold cavities, and a pressure regulating system regulates pressures inside the first and second mold cavities. An injection molding method includes providing a molding device having a first and second mold cavities, a first feeding port in communication with the first mold cavity, and a second feeding port in communication with the second mold cavity; sensing a first pressure in the first mold cavity, and injecting a first gas into the first mold cavity until the first mold cavity is sensed to have a first predetermined pressure; and sensing a second pressure in the second mold cavity, and injecting a second gas into the second mold cavity until the second mold cavity is sensed to have a second predetermined pressure, wherein the first and second predetermined pressures are different.

A method of producing a container product comprises providing a mold including a first part and a second part. The mold is closed to define a cavity having a first area and a second area. A molten plastic composition including a polymer and a physical blowing agent is filled into the cavity. Then, the molten plastic composition in the cavity is cooled, such that the molten plastic composition in the first area is completely cooled and solidifies or a central portion of the first area has micro uncooled molten plastic composition. The second area has the plastic composition in the molten state. The first part of the mold is moved in the axial direction. The molten plastic composition in the second area forms a beehive foam after foaming and expansion. Then, the foamed container product in the mold is cooled to take shape and then removed after opening the mold.

An at least partially transparent optical component is provided for use in a motor vehicle. The component has a length (L) along a first axis (X), a width (B) along a second axis (Y) that is at a right angle to the first axis (X), and a thickness (D) along a third axis (Z) that is at a right angle to the first and second axes (X, Y). The length (L) and width (B) are significantly greater than the thickness (D). The thickness (D) of the component (10) is between 0.4 mm and 4.0 mm. The component is produced in an injection molded foam process.

A method for manufacturing a foam-molded article by performing a GCP, the method including a step of retreating a mobile side of a mold clamping mechanism of a sealed mold at the same time as when a step of discharging a gas is started, during the step of discharging the gas, immediately after the step of discharging the gas or when a specified delay time after the step of discharging the gas is finished for performing at least one of a mold-back and a core-back to increase a foaming ratio of a foamable resin in a state that a cooling and a solidification of an inside of the foamable resin are not finished.

A system including an injector, a press, and a robotic conveyance is used to form a physically foamed article of footwear component from a single-phase solution of a polymeric composition and a supercritical fluid. The parameters and features of the system are configured for the formation of the footwear component in an automated manner with enhanced throughput by the system.

Tooling and components of an injection-molding system may be used to mold a foam article. The tooling and components may include features that control parameters of the injection-molding and foaming process, such as temperature, pressure, shot size, shot placement, and the like.
