Tandem Extruder | Cascade Extruder | Two Stage Extruder
The unique configuration of the Two-stage extruder machine is designed to combine the excellent mixing performance of the high-speed parallel Twin screw extruder with the advantages of the low-speed single-screw extruder’s low-temperature stability for a more efficient production process and better product output.
The Two-stage machine is characterized by its unique structural design. The first stage is the GTE high-speed parallel Twin screw extruder
, which uses the high dispersion and strong shear of the twin screw to complete the plasticization and dispersion quickly and fully. At the same time, because the screw is a building block structure, the screw combination can be adjusted arbitrarily according to different materials in order to achieve the best mixing state of the material. The second stage is GDE low-speed single-screw extusion machine, used for low-temperature extusion, due to the single-head deep groove structure of the single screw, which helps to stabilize the pressure of the melt in the extusion process, the single-screw barrel is equipped with heating and cooling, which can accurately control the extusion temperature and avoid excessive decomposition of the melt. Two-stage extusion machine combines the characteristics of high speed and strong mixing of twin screw and the characteristics of low speed, low temperature and weak shear of single screw, maximize the advantages of equipment and greatly improve production efficiency. The two machines are placed vertically to save space and provide continuous production line layout.

Structure:
Stage 1 is GTE high-speed co-rotating twin-screw extruder. Stage 2 is GDS low speed single screw extruder. Two machines are placed vertically.
Principle and applications:
◆ The synthetic twin-screw and single screw advantages combined with complementary. Twin screw extruder forced transfer, mixing and dispersing efficient plasticizing, no head die backpressure backflow.
◆ To avoid the high shear overheating; Single screw high pressure extrusion, but low shear at low speed, also avoid the overheating of contradictions.
◆ Twin screw and single screw combination, function decomposition, the process increases the independent variable, operation for each process step by step optimization; Higher efficiency and capacity.
◆ They are widely used in all kinds of heat sensitive material system and big volume to take off the swing homework, such as PVC,XLPE, halogen-free flame retardant cable, shielding material, highly enriched carbon black and rubber dehydration post-processing operation etc.

Bred applikationserfarenhet
Biologiskt nedbrytbar plast är en plast som är nedbrytbar av naturliga mikroorganismer som bakterier, svampar och alger. En idealisk biologiskt nedbrytbar plast är ett polymert material som fungerar bra, kan sönderdelas helt av mikroorganismer efter kassering och i slutändan blir en del av kolets kretslopp i naturen genom oorganisering.
Color masterbatch är en integrerad del av plastindustrin. Det kan inte bara ge färg till plastprodukter, öka värdet på varor, förbättra viss prestanda hos plast, utan kan också ge speciella optiska egenskaper till material.
Startade på 1940-talet används de nya funktionella polymererna, som i första hand omfattar alla typer av ingenjörsplaster (såsom PA, PC, ABS, PET, PPS, etc.), redan inom elektronik, elektriska apparater, fordons-, transport-, flyg-, försvars- och militärindustrier, etc.
Filler masterbatch finns för bearbetning av plastfilmer, soppåsar, shoppingkassar, undertröjor, förpackningspåsar etc. Den har utmärkt spridning, blåst film utan vita och svarta fläckar och hög finhet för att säkerställa produktens lyster och seghet.
Icke-kristallisation torr PET-plåtextrudering erbjuder flera fördelar. Den används för att producera PET/PLA-plåt utan energiförbrukning av förtorkningskristallisering och anpassning till produktion av material med hög effekt, låg energiförbrukning och hög plastkvalitet.
Rengöringslinjen för PET-avfallsplastflaskor innebär att plastavfallsflaskorna avmärks av avetiketteringsmaskinen, pulveriseras av krossen och sedan bearbetas av rengörings- och torkutrustning, så att återvinning och integration av avfallsplastflaskor blir en ny typ.
Termoplastisk elastomer har omfattande justerbar hårdhet och fysikaliska egenskaper. Dessutom behöver den inte vulkaniseras, är återvinningsbar och kan minska kostnaderna, så användningsområdena är relativt breda inklusive tätningar, bilinteriörer, limbelagda material, olika rördelar, etc.
