摘要： A system for controlling the manufacture of dimensionally varying tubular members extrudes a continuous tube with a lumen from an extrusion machine. The extrusion machine has a melt pump, which regulates the flow rate of the melt through the extrusion head. The extrusion head forms a melt flow and introduces air pressure within the melt flow to form the lumen of the tubing. An air pressure regulator controls the pressure of the air introduced through the extrusion head. A puller supplies tension to the tubing as it is extruded through the extrusion head. The system uses a diameter gage and/or a wall thickness gage to measure the change in the wall thickness of the tubing as a function of its length. Further, the system uses a laser to gage the profile of the tubing. The system automatically compares the measured dimensions against stored dimension targets to generate feedback to the components of the extrusion machine, automatically adjusting one or more process variables for the next tubular member in the extrusion sequence. Finally, the system sorts the tubular members that fall within acceptable error margins, and sorts out those that fall outside the error margins.

摘要： Disclosed are techniques for mitigating vent flow into a vent attachment on an extruder vent of an extruder. The vent attachment has a vent attachment port configured to release gases from the extruder vent. The techniques include monitoring temperature via a temperature probe mounted at least partly inside an interior opening of the vent attachment. The temperature probe is communicatively coupled to a programmable logic controller (PLC). A region of the vent attachment adjacent the temperature probe is cooled so as to reduce an operating temperature of the region and of the temperature probe. Vent flow is detected in response to the PLC determining a rate of temperature change of the temperature probe exceeding a predetermined threshold rate and thereby indicating presence of the material in the vent attachment port.

摘要： A startup control method of a resin extruder is provided. The resin extruder extrudes supplied resin material to a die as molten resin by rotating a screw. The resin material is supplied with a low supply amount which is smaller than a target supply amount and the screw is rotated at a low rotational frequency which is smaller than a target rotational frequency when starting the resin extruder. A supply amount of the resin material and a rotational frequency of the screw are gradually increased. After elapse of a set startup time, the supply amount of the resin material is brought into a target supply amount and the rotational frequency of the screw is brought into a target rotational frequency.
