A casting apparatus for producing hollow cast objects (24) comprises - a cavity (14), - a filling apparatus (18) for filling flowable casting material (16) into the cavity (14), - a displacement apparatus (22, 30) which is configured for displacing, by means of pressurized fluid, a part of the casting material (16) which has been filled into the cavity (14), wherein the displacement apparatus (22, 30) comprises a nozzle arrangement (22) for this purpose. According to the invention, the nozzle arrangement (22) which ejects the pressurized fluid can be moved into the cavity (14) and out of the latter.
A casting device for producing hollow cast objects comprises a cavity, a filling device for filling flowable casting material into the cavity, a displacement device designed to drive a projectile (10) into, preferably through, the casting material filled into the cavity, wherein the projectile extends along a projectile longitudinal axis (12), and wherein the projectile (10) has a non-rotationally symmetrical cross-section in at least one axial contour section (48) of the longitudinal extension thereof.
A casting device (10), in particular injection-moulding device (10), for producing at least partially hollow objects comprises a filling device (12) which is designed for pouring flowable casting material into a main cavity (18), and a displacement device (14) which is designed, upon the activation thereof, to displace some of the casting material poured into the main cavity (18) into a secondary cavity (20) which is or can be brought into flow connection with the main cavity (18), wherein the secondary cavity (20) can be at least partially, preferably completely, heated.
INJECTION-MOULDING PROCESS FOR PRODUCTION OF A COMPONENT WITH AT LEAST TWO FUNCTIONAL COMPONENTS DESIGNED TO BE MOVABLE SEPARATELY FROM ONE ANOTHER AND RELATIVE TO ONE ANOTHER
An injection-moulding process for production of a component with at least two functional components designed to be movable separately from one another and relative to one another in a shared injection mould (10) encompasses the following steps: injection of flowable moulding composition into at least one first mould cavity (26) to form a first functional component using a first injection pressure and a first hold pressure, injection of flowable moulding composition into at least one second mould cavity (28,30) to form a second functional component using a second injection pressure different from the first injection pressure and a second hold pressure different from the first hold pressure, where one injection pressure, from the first injection pressure or second injection pressure, higher than the respective other injection pressure, and the hold pressure associated with the higher injection pressure higher than the respective other hold pressure have been selected in such a way that the functional component formed using the higher injection pressure and using the higher hold pressure has negative shrinkage.

A plastic container (10) comprises a container body (12) and an electrically conductive electrode device (28) which is arranged on the container body (12) in such a manner that at least one section (34) of the electrically conductive electrode device (28) is exposed inside (26) the container body (12) in order to be contact-connected by material which has been poured or can be poured into the container body (12), wherein at least sections of the electrically conductive electrode device (28) are formed from electrically conductive plastic.
G01F 23/24 - Indicating or measuring liquid level or level of fluent solid material, e.g. indicating in terms of volume or indicating by means of an alarm by measuring physical variables, other than linear dimensions, pressure or weight, dependent on the level to be measured, e.g. by difference of heat transfer of steam or water by measuring variations of resistance of resistors due to contact with conductor fluid
Disclosed is a vehicle underbody part (10), particularly an underbody panel or a wheel arch panel, which is embodied as an injection-molded plastic part and comprises at least one opening (11) closable by means of a cap (15) that is to be opened. The cap is connected to the underbody part (10) via a joint piece (14) while the underbody part (10), the joint piece (14), and the cap (15) are formed by a monolithic injection-molded plastic part.
The invention relates to a method for producing a panel or housing part (20) of a vehicle, especially an underbody guard or a wheel house panel. A semi-finished product (10) which comprises at least one core layer (11) in the form of a nonwoven from high-melting and low-melting fibers is heated above the melting temperature of the low-melting fibers and shaped in a mold (16), while adding pressure, to give the panel or housing part. The semi-finished material is compacted in the mold in some high-density regions at the edge of the panel or housing part and/or at a distance to the edge to give monolithic regions (III) that are substantially devoid of gas bubbles to such an extent that the material of the semi-finished product in these high-density regions flows along the mold gap while the intermediary porous regions (A, B, C) retain the porosity of the nonwoven of the core layer.
