There is disclosed a member for sealing, baffling and/or reinforcing components of an automotive vehicle. The assembly generally includes a carrier, an expandable material and at least one fastener.

A producing method for producing a foam-molded product by using a plasticizing cylinder having, from an upstream side in the following order: a plasticization zone, a flow rate adjusting zone and a starvation zone, the producing method includes: plasticizing and melting a thermoplastic resin into a molten resin in the plasticization zone; adjusting a flow rate of the molten resin in the flow rate adjusting zone; allowing the molten resin to be in a starved state in the starvation zone; introducing a pressurized fluid containing the physical foaming agent having a fixed pressure into the starvation zone so as to retain the starvation zone at the fixed pressure; bringing the molten resin in the starved state in contact with the pressurized fluid in the starvation zone in a state in which the starvation zone is retained at the fixed pressure; and molding the molten resin into the foam-molded product.

A process for the extrusion of plastics, such as plastics that tend to adhere or stick to parts of an extruder, using a planetary roller extruder in the feed part.

A molding apparatus, a cigarette filter rod and a preparation method thereof are disclosed. The molding apparatus comprises a single-screw extrusion system and a cooling setting system. The single-screw extrusion system comprises a feeder and an extruder. The feeder is arranged on the extruder. The extruder comprises a cylinder. A heater is arranged outside the cylinder. A screw is arranged inside the cylinder, and a mouth mold is arranged at one end of the cylinder. The cooling setting system comprises a round tube and a cooler. The cooler (6) is arranged outside the round tube. One end of the round tube is butted with the mouth mold of the extruder; and multiple groups of grooves are formed on threads of the head of the screw.

An installation for producing a polymer melt for a porous film, in particular for a membrane film, comprises a planetary roller extruder. Said extruder is used to produce a flowable polymer melt from thermoplastics. The planetary roller extruder has a filling opening and a discharge side for delivering the polymer melt. A melt pump is further provided. The discharge side of the planetary roller extruder is connected to a downstream inlet side of the melt pump for further conveying the polymer melt. The connection is in the form of a pressure channel shielded from the ambient atmosphere or a pressure line shielded from the ambient atmosphere. The planetary roller extruder and the melt pump are designed and/or can be driven in such a manner that the polymer melt is applied or can be transferred under pressure at the melt pump on the inlet side.
