The invention relates to a welding tool and a method for pulse welding films of plastic for medical packs formed as bags. The invention generally provides for the film material that has been plastified during welding, and is consequently free-flowing, to be specifically displaced by increasing the sealing surface area. The displaced film material can for instance compensate for dimensional and form tolerances. At the same time, however, the strength of the welded seam region, which adjoins the interior space of the bag, is not reduced.

An object of the present invention is to propose a bending die capable of creating a product without causing buckling, even if the shape of the product is long or bent freely in three-dimensional space. The bending die according to the present invention is a bending die having a smooth shape formed by virtually and continuously moving, in three-dimensional space, a profile including a substantially circular-shaped first closed curve having a recess portion, wherein an opening width b of the recess portion is shorter than a groove width a of the recess portion, a tube insetting portion is formed by the recess portion, and the smooth shape is realized and created in real space using a three-dimensional printing technique.

An injection mold insert includes a housing of a first material and an inner core of a second material sealed in the housing of the first material. A mechanical strength of the first material is greater than that of the second material. The thermal conductivity of the second material is greater than that of the first material. The inner core is formed by filling a molten liquid of the second material into an inner cavity of the housing.

A method for manufacturing a panel for an aircraft is provided. The method includes arranging, on a curing surface, a skin of pre-preg composite material, arranging a plurality of pre-formed, uncured composite stringers, each having an open cross section with a web and a base transverse to each other so that a first base portion protrudes toward a first side and a second base portion protrudes toward a second side, arranging the stringers on the skin with the base in contact with the skin, arranging, on each stringer, a respective first mandrel to completely cover the first base portion and a respective second mandrel to completely cover the second base portion, and having the skin and the stringers undergo a co-curing process in autoclave with vacuum bag.

A method of forming shaped articles by welding.

A blow molding tool (1) for a blow molding machine (1). The blow molding tool (1) comprises at least one first blow mold half (2) and one second blow mold half (3). The first blow mold half (2) has a baseplate (4) and a molding body (5). At least one mold cavity (6) with an inner wall (51) is arranged in the molding body (5). At least one region (511) of the inner wall (51) of the mold cavity (6) comprises, in the associated section of the molding body (5), separate temperature control channels (54) for controlling the temperature of the region (54).

Described herein are expandable foaming molds. The foaming molds described herein permit mold boundaries to expand along with the expanding polymer and thereby conform to the foaming dynamics of the polymer material. By modifying the temperature and pressure applied to the mold devices described herein, the properties of the resulting foamed polymer can be fine-tuned for specific applications.

A method for forming a tool for creating a formed component includes providing a forming tool having a core and cavity with respective core and cavity shutoff bands. Core and cavity finished parting planes are determined, wherein the engagement of the core and cavity finished parting planes defines a forming cavity. Rough portions of the core and cavity shutoff bands are removed to define respective rough parting planes. The respective rough parting planes are offset by approximately 130 microns from the respective core and cavity finished parting planes. The core and cavity are semi-finished to relieve stress within the core and cavity. The core and cavity shutoff bands are fine cut so that outer surfaces of the core and cavity shutoff bands are equal to the respective finished parting planes. The engagement between the core and cavity outer surfaces is substantially free of gaps.

The invention relates to a blow molding tool for a blow molding machine for producing plastic containers in an extrusion or stretch blow-molding process. The blow molding tool comprises two blow mold halves, each of which comprises at least one molding body in which at least one mold cavity is disposed, and a baseplate that receives said molding body. An insulation block consisting of a thermally insulating material is arranged between the molding body and the baseplate and, optionally, further components of the blow mold halves.
