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.

The present disclosure concerns an apparatus and a method for injection molding of an elongated hollow article, such as a urinary catheter, said apparatus comprising a heated central mold with an inlet opening for entering liquid molding compound into a substantially tubular cavity formed in said central mold; an elongated central mold core which is provided in the tubular cavity and extends beyond said tubular cavity and into a tip mold cavity of a tip mold part which is aligned with the tubular mold cavity in the longitudinal axis of the central mold core; wherein the tip mold part is moveable in a linear movement in a direction along the longitudinal axis of the elongated central mold core.

A microbubble creating method using a forming machine for creating microbubbles by: installed a microbubble generating member in a mold, feed screw or barrel for enabling a perforated tip of the microbubble generating member to be surrounded by the applied fluid polymer so that when a high pressure high temperature gas is delivered through the perforated tip of the microbubble generating member, microbubbles are created with well mixed with the fluid polymer, and the expected foamed polymer product is thus obtained after cooling.

A structural component serves as a container for a vehicle. The structural component comprises a trough-shaped container section, an edge region, and fastening elements that are provided in the edge region. The container section forms a compartment and defines a bottom region and two or more wall regions, which are at least sectionally inclined with respect to the bottom region. The two or more wall regions are arranged between the bottom region and the edge region. The fastening elements are arranged and distributed around the container section. The container section and the edge region are formed of an injection moldable fiber reinforced thermoplastic material. The structural component at least sectionally has a porous internal structure that is formed by foaming the thermoplastic material.

An injection molding apparatus includes an injection unit, a mold clamping unit, and a controller. The mold clamping unit includes a toggle fixing portion, a fixed mold attachment portion, a movable mold attachment portion, a motor, a ball screw, a crosshead, and a toggle section configured to move the movable mold attachment portion along a mold clamping direction. The toggle section includes a first member associated with a first rotary shaft, a second member associated with a second rotary shaft and a third rotary shaft, and a third member associated with a fourth rotary shaft. A length of a line connecting a center of the first rotary shaft and a center of the second rotary shaft is equal to or longer than a length of a line connecting a center of the second rotary shaft and a center of the third rotary shaft.
