An injection molding assembly comprising a collapsible core assembly, an injection mold press comprising an internal cavity configured to receive the collapsible core assembly, and an actuator configured to insert the collapsible core assembly into the internal cavity of the mold press and method of using the same. The collapsible core assembly may comprise a static core member, a moveable core member coaxial to the static core member and moveable relative to the static core member, and a stripper plate moveable within the collapsible core assembly relative to the static core and configured to eject the molded part. The moveable core member may comprise an external engagement feature disposed at an end of the moveable core member. The external engagement feature may define a geometry operable to matingly engage an internal feature of a molded part supported on the moveable core member upon formation of the molded part.

The disclosure relates to a container, such as a primary packaging container for pharmaceutical, medical, cosmetic, dietetic and/or food products. The container may include an interior surface with at least one undercut section. At least a portion of the container may have an average wall thickness of maximally 0.8 mm, between 0.2 mm and 0.8 mm, between 0.3 mm and 0.7 mm, or between 0.4 mm and 0.6 mm.

The present invention relates to a luggage, having an integrated structure. The luggage includes a one-piece shell, which is constructed from a single molding to form a continuous structure and has at least a top wall and two opposing side walls. The top wall has two sloping curved corners which are sloped and curved toward the cover of the luggage and the respectively abutting side wall. The present also invention provides a method of manufacturing the luggage. The method includes the steps of assembling a family mold to form a mold cavity, injecting mold material into the mold cavity to make the one-piece shell for the luggage, and removing the family mold. The family mold includes an inner mold tool and an outer mold tool, and the step of removing the family mold includes the steps of removing the outer mold tool first, and then, removing the inner mold tool.

A valve housing for a fluid valve having at least one fluid channel through which a fluid can flow is provided. The valve housing can have a receiving space for a valve closing body movable in the valve housing, the receiving space having an opening, via which the valve closing body is introduced into the receiving space of the valve housing, and at least one first valve seat being formed in the receiving space and projecting into the receiving space in such a way that at least one undercut is formed in the receiving space by the first valve seat, and the valve housing being an integral injection-molded part, the at least one valve seat being produced integrally with the valve housing by an injection molding process.

An injection molding method and a deformable molding unit are provided. The method includes the following steps. First, a mold positioning step is performed to define a mold cavity. The step includes: providing a deformable molding unit on a first axis, the deformable molding unit having a deformable cavity and including a bottom portion and a first elastic portion being elastically deformable with respect to the bottom portion; and applying a first compression force to the first elastic portion by a first drive module along a second axis, reducing the size of the deformable cavity to a reduced dimension. Next, plastic is injected into the mold cavity including the deformable cavity with the reduced dimension to form a workpiece. Then, the first compression force is released, allowing the deformable cavity to return to its original dimension. Afterward, the deformable molding unit is retracted along the first axis.
