POTS WITH UNDERCUTS, OPENING MOLDS, FORMING MACHINES, AND PRODUCTION LINES FOR POTS WITH UNDERCUTS
Pot with an undercut that includes a bottom wall (5), a side wall (6) that is closed on itself and connected to the bottom wall (5), with an opening providing access to the interior of the pot. The outside surface of the side wall of the pot has a non-symmetrical undercut shape for rotation around the vertical direction (Z). The outside surface has at least one vertical demolding plane (P) such that an undercut value of the pot with respective side ends of the pot, with a maximum side spacing of the outside surface in relation to the vertical demolding plane (P), is less than a maximum undercut value of the pot on the circumference of the outside surface of the pot.

Mold with separable features
A mold comprises a main body and a separable feature. One or more weakened regions join the separable feature to the main body. The one or more weakened regions are breakable to enable the main body to be removed from a shell independently of the separable feature after the shell is formed over the mold.

Mold with weakened areas
A breakable or deflectable mold includes a first section, a second section, and a weakened region that joins the first section to the second section. The weakened region is breakable or deflectable to enable the first section to be removed independently of the second section after a shell is formed over the breakable mold.
Molding tool and molding method for producing containers with undercuts
A molding tool (1000), in particular a thermoforming tool, for producing a container (10) is provided. The molding tool comprises a mold bottom (200) and a mold insert (100) receiving the mold bottom (200), wherein the mold insert (100) is constructed of at least two mold insert parts (110, 120) that together with the mold bottom (200) define a cavity (300) provided for reshaping a two-dimensional web of material into a container, wherein a first mold insert part (110) is mounted stationary in the molding tool (1000) and a second mold insert part is axially movable in the molding tool (1000).

Multi-cavity mould, a heating element for forming a smooth periphery for thermoformed thin-gauge plastic products and method for forming such a periphery
A multi-cavity mold (1) for a thermoforming machine used in high-volume, continuous thermoforming of thin-gauge plastic products (2) from a preheated thin-gauge thermoplastic sheet (3) comprising an upper tool (11) and a lower tool (12) arranged in a cooperating manner; the lower tool (12) comprising cavities (8) in which cavity molds (8) are placed and base plates (91) from which supporting blocks (92) extend perpendicularly over a predetermined total height (a), situated between adjacent cavities (8), each supporting block (92) comprising two zones, a first substantially rectangular shaped zone (92a) and a second substantially isosceles trapezoid shaped zone (92b) in a vertical cross section through a y-z plane and two vertical channels (81) to alter, during forming of the products (2), a thickness of a peripheral flange (B), to decrease from a medium thickness (t) to a lesser thickness (t1).

Method and device for manufacturing containers by thermoforming
The containers are thermoformed at a thermoforming station from blanks cut out from a sheet of thermoplastic material. Before thermoforming the containers, at least some blank zones in the sheet are heated, the hot blanks are cut out from the heated zones and the hot blanks are conveyed to the thermoforming station.
