摘要： In accordance with one embodiment of the present invention, a system for controlling the properties of an extrusion from a production line is provided. The production line comprises a raw material feed, a mixer, and an extruder. The control system comprises one or more ammeters electrically coupled to an electrically driven mixing motor and an electrically driven extrusion motor. Output signals indicative of the load amperes IM of the mixing motor and the load amperes IX of the extrusion motor are provided. The controller is in communication with the raw material feed and the ammeter and is programmed to compare the load amperes IX of the extrusion motor to the load amperes IM of the mixing motor and determine whether a result of the load ampere comparison warrants modification of an operating parameter of the production line. If so, the controller modifies one or more operating parameters of the production line to account for the variation from the target value. Additional embodiments are disclosed and claimed.

摘要： It has been discovered that the melt instability of styrenic polymers, particularly high impact polystyrene (HIPS) can be reduced or eliminated by the blending therewith of a relatively high melt flow index (MFI) material, such as polystyrene homopolymer. Draw resonance of the melt blend can also be reduced by this method, thereby improving melt processing of these materials. A method to measure melt instability of drawn materials is also discussed.

摘要： The invention relates to a material conveying device for feeding at least one injection molding and/or extrusion unit with a non-free-flowing or viscous feed material, having a feed hopper rotatable relative to a bracket about an axis of rotation and a screw conveyor arranged rotatably along an inner jacket surface of the feed hopper in a screw shaft of the bracket, which is designed to convey the feed material from the feed hopper to an outlet, wherein the screw shaft is connected to a hopper outlet of the feed hopper, and wherein the screw conveyor is drivable via at least one drive device.
In order to enable the conveying of feed materials with different properties in the simplest possible way, it is provided that at least one media feed channel opens into the screw shaft, which is designed to feed at least one additional medium to the feed material, wherein at least one mixing device is arranged in the region of the screw conveyor and/or downstream of the screw conveyor, which is designed to mix the feed material and the additional medium.

摘要： An apparatus for extruding plastic, including a plastic feed, an extruder, a colored liquid additive supply, a positive displacement metering pump, and a controller. The extruder has a housing receiving plastic from the plastic feed, a heat source, and a screw adapted to drive plastic through the housing The pump supplies colored liquid additive from the supply to the plastic in the phase change section of the extruder housing. The controller controls the drive rate of the screw and the pump to supply a selected volume of colored liquid additive per unit of time which is based on the drive rate of the screw. In use, the extruder is converted to adding a different color without cleaning the housing feeding section.
