Described is a process and system for direct printing of a decorative pattern onto an extruded PVC slat. The process includes providing a hot extruded PVC slat; directly contacting a surface of the hot extruded PVC slat with a direct printing cylinder as the slat is moved in a downstream direction, where the cylinder has a pattern with a cell structure that receives ink and rotates to directly apply the ink in the form of the pattern onto the surface of the hot extruded PVC slat. The process also includes controlling a temperature of the direct printing cylinder to inhibit drying of the ink while present on the direct printing cylinder.

A method for forming an uncured rubber component, the method includes conveying an uncured extruded rubber strip extruded continuously from an extruder using a conveyor, the conveyor including a first conveyor and a second conveyor located at a downstream side of the first conveyor in a convey direction, the step of conveying including shrinking the uncured extruded rubber strip, wherein the step of shrinking is such that the uncured extruded rubber strip, in a relaxed state of a U-shaped manner, passes through fluid held in a tank between the first conveyor and the second conveyor without being restrained so that the uncured extruded rubber strip shrinks freely while receiving buoyancy from the fluid, and cutting the uncured extruded rubber strip in a predetermined length to form an uncured rubber component, after the step of shrinking.

A system and method for reducing draw resonance of a plastic material in molten state, so-called melt, leaving an extrusion group of a plant for the production of plastic film, includes at least one thermostatically-controlled cylinder, having an embracement angle of the melt on the cylinder that is adjustable on the basis of the process rate, i.e., the linear movement speed of the plastic film, and/or on the basis of the temperature measured in the proximity of or in correspondence with the clamping area of the melt in a thermoforming, calibration and cooling group included in the plant and positioned downstream of the system.

A method of recycling a mixed plastic waste comprising plastics having different melting temperatures includes conveying the mixed plastic waste through an extruder such that at least some of the higher melting point plastic is passes through the extruder without melting and is present in the extrudate as solid material.

An extruder and molding assembly comprising an extruder positioned upstream from a mold, the mold having a mold cavity and a separate pressurization member fluidly connected to the mold cavity wherein the extruder is operable at a first pressure to fill at least a majority of the mold cavity and the pressurization member is operable to fill a remainder of the mold cavity.

To provide a biaxially oriented polyester film that has extremely low content of antimony, excellent hygiene, few foreign substances, excellent transparency and heat resistance, and is excellent in printability, workability, and productivity. A biaxially oriented polyester film characterized by a content of antimony in the film of 10 ppm or less, a content of phosphorus in the film of 25 ppm or more and 75 ppm or less, an intrinsic viscosity of the film of 0.51 dl/g or more and 0.70 dl/g or less, and a number of defects with a size of 1 mm or more is 1.0 or less per 1000 square meters of the film.

A molding apparatus that adsorbs thermoplastic resin extruded in a sheet form from an extruding machine, onto a cavity of a mold, and shapes the thermoplastic resin into a shape according to the cavity is provided. The molding apparatus may include a frame that is positioned on a periphery of the mold and is movable relative to the mold, wherein a suction part for suctioning the thermoplastic resin is provided in a contact surface of the frame to contact the thermoplastic resin, and the suction part is provided in a linear shape along with a longitudinal direction of the frame positioned on the periphery of the mold.

A method and apparatus for manufacturing a duct bank comprising the steps of loading a frame with a series of templates, positioning the frame adjacent a pipe extruder, aligning a set of a plurality of holes with a die of the pipe extruder, extruding a pipe of a first length into the set of holes, repeating the steps of aligning and extruding for each set of holes, thereby forming the duct bank, banding the duct bank, and removing the duct bank from the frame.
