Apparatus for feeding single grains to one or more processing machines comprising at least one singulating device, a granular material reservoir for a bulk material, and a feeding device for feeding the singulated bulk material to the injection molding machine. The singulating device is formed from a singulating disk provided with suction openings distributed over the pitch circle. On one side of the singulating disk, the granular material reservoir is arranged to hold bulk material. Via the shaft, the singulating disk is mounted to be rotated with the suction openings for receiving and dispensing grains. Furthermore, a grain scraper and/or a grain aligner for the bulk material or grains is arranged on the singulating disk in order to scrape off the grains and/or align the grains, or a stirring or carry-along element is arranged on the singulating disk for receiving the bulk material or on the shaft.

A system and method for creating a rigid foam substitute is provided. By using natural binding materials and natural fiber materials, the system and method may be used to create environmentally friendly substitutes for expanded polystyrene. The system generally comprises a processing room and molding facility. The processing room may comprise an opener, cleaner, and blower, which may be used to break up and clean the natural fiber material. The molding facility may comprise a mixer, molder, and kiln, which may be used to create casts. The method generally entails processing a natural fiber material before mixing it with a natural binding material and fluid to create a fluidic mixture, wherein said fluidic mixture is subsequently molded and cured to create a finished product.

An ultralow-gloss polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) resin composition and a preparation method thereof are provided. The composition includes the following components: 40-80 parts by weight of bisphenol A polycarbonate, 19-40 parts by weight of acrylonitrile-butadiene-styrene graft copolymer, 1-20 parts by weight of ultralow-gloss toughening modifier, and 0.1-5 parts of processing aid. The ultralow-gloss toughening modifier includes the following components: post-treated polymeric microspheres, a low-temperature toughening agent, a coupling agent, and aid. The preparation method of the composition includes: fully mixing all components in a high-speed mixer to obtain a mixture; feeding the mixture into a main feed port from a twin-screw extruder, melting, extruding, cooling, drying, and pelletizing. The PC/ABS resin composition prepared by the present invention has extremely low gloss level and excellent impact toughness, and it can be applied in scenarios requiring low temperature resistance and low gloss level.

A control method of feeding weight of plastic particles based on speed regulating motor and weight feedback is characterized in that it includes a central processor (71), which is electrically connected to a motor controller (72), and the motor controller (72) drives a actuator (73) to drive a controlled object (74) to complete an operation, so that a mixing bin (4) outputs the corresponding amount of materials, and characterized in that a detection device (75) is set on the controlled object (74), and the detection device (75) is communicated with the central processor (71).
