A method of producing a bioplastic granulate on the basis of sunflower seed shells or sunflower seed hulls. In the method, ground sunflower seed shells/sunflower seed hull material is provided, wherein the particle size is in the region of 3 mm or less, preferably in the region of 0.01 to 1 mm, preferably in the region of 0.1 to 0.3 mm. A plastic material is provided, which is compounded with the sunflower seed shells/sunflower seed hull material, wherein the compounding operation is preferably effected in an extruder, preferably a double-screw extruder. The compounded material is chopped at the end of the extruder section with a tool with the addition of water, wherein the water is at a temperature of preferably more than 50 C., preferably about 80 to 90 C., to cool down the compound material. During the compounding operation, the compounding material is subjected to atmospheric degassing and/or vacuum degassing.

A method for producing a rubber member according to the present invention includes the steps of: supplying a rubber composition to a cylinder provided in an extruder; extruding the rubber composition to a downstream side of the cylinder while kneading the rubber composition in an internal space of the cylinder that includes a plurality of protruding members protruding from an inner wall surface of the cylinder; compressing the rubber composition at least once in the step of extruding the rubber composition to the downstream side; discharging a gas generated from the compressed rubber composition to outside of the cylinder; discharging, through a discharge outlet of the cylinder, the rubber composition after the gas has been generated; and molding the rubber composition that has been discharged through the discharge outlet into a predetermined rubber member shape.

Methods and an apparatus are presented. A bulk molding compound is consolidated by sending the bulk molding compound through a die breaker and an extrusion die of a consolidation system.

A feeding screw machine for feeding a processing screw machine comprises a housing with at least two housing bores formed therein and screw shafts rotatably arranged in the at least two housing bores. The at least two housing bores and the at least two screw shafts define a free volume in a respective cross-sectional plane, which decreases monotonically at least in some regions for continuous compression of a material in a conveying direction. This enables an improved supply of material with a low bulk density.
