摘要： In a method for producing a coiled tubing (RW) from a thermoplastic material, in a first shaping step a tubular extrudate (EX) is extruded via an annular nozzle gap (16) in an extruder (12) before, in a second shaping step directly following the first shaping step, the extrudate which is drawn down from the nozzle gap and is still plastically deformable is calibrated in a shaping device (18) in order to obtain a geometrically defined profile cross section (PQ) and is shaped into the coiled tubing, whereupon the coiled tubing having the geometrically determined profile cross section solidifies. This method allows for continuous production of the coiled tubing with a new, high quality in respect of dimensional and shape tolerances on the profile cross section of the coiled tubing. The invention also relates to a device (10) for producing such a coiled tubing.

摘要： Plastic profile extrusion system includes an extrusion die that pre-forms a hot, unfrozen plastic profile shape. Cooled calibration device receives the hot plastic in a longitudinal cavity through the calibration device to conductively cool the plastic as it holds the plastic profile to size and dimensions. For plastic parts with channels, inside corners, or other difficult to cool sections, the calibration device would require a metal ridge to hold the shape of that channel or corner as the heat is conducted from the hot plastic through the metal ridge into the body of the calibration device. This invention replaces metal ridges that hold the shape of the plastic profile during cooling in at least part of the calibration device with fluid cooling passages that communicates with the moving portion of the plastic profile and cooling medium to fill the flow passages to extract heat from the plastic material.

摘要： The present invention relates to the technical field of optical film production, and provides a light guide film production device, including a feeding unit, a fusion stirring unit, an extrusion molding unit, a cooling shaping unit, a guide leveling unit, a flattening unit, and a finished product winding unit. The cooling shaping unit is provided with a first water tank to perform heat exchange on an extruded light guide film for heat recovery, so that edge film pressing mechanisms press pressure blocks at the edge film positions using the memory effect of a memory alloy. Circulating water of the first water tank subjected to heat exchange is delivered to a second water tank disposed in the flattening unit, so that a first conveyor belt made of the memory alloy in a third drive device drives a second rolling roller set to rotate to realize secondary utilization of recovered heat. In the present invention, an air delivery mechanism with one airflow pipe to the cooling shaping unit, and the other airflow pipe to the flattening unit is further provided. According to the present invention, the heat of the light guide film production process is used to improve the quality of the light guide film and reduce the energy consumption of the light guide film production process.

摘要： Mold blocks of a pipe molding corrugator are provided with enhanced cooling capability due to the provision of cooling fins on the side portions of each mold block. Air can be forced between the fins and some exhaustion of the air can occur at the base of the fins adjacent the mold block cavity. With this arrangement, enhanced cooling of mold blocks is possible.
