After more than 100 years of development, plastic pelletizing extruders have been derived from the original single screw, such as twin screw, multi screw, and even screwless models. Plastic pelletizing extruder (main machine) can be formed with various plastics such as pipes, films, holding materials, monofilaments, flat filaments, packing tapes, extruded nets, plates (sheets), profiles, pellets, and cable coatings. Auxiliary machines are matched to form various plastic extrusion molding production lines to produce various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used machines in the plastic processing industry, now and in the future.
Tandans devlopman plastik extruder plastik se konsa:
(1) èkstrudè yo ap devlope nan direksyon pou gwo - echèl, segondè - vitès, ak segondè - efikasite. Extruders Plastik plastik ak dyamèt vis nan 200 - 250mm yo trè komen. Èkstrudè espesyal ak dyamèt vis ki pi konsekan pase 400mm pa estraòdinè. Ogmante dyamèt nan vis la ka ogmante kapasite pwodiksyon an nan èkstrude la. Lè yo dyamèt vis la double, ka kapasite pwodiksyon an nan èkstrudè a ap ogmante plizyè fwa.
Yon lòt metòd efikas ogmante kapasite pwodiksyon se ogmante vitès la nan vis la. High - vitès ak ultra - segondè - èkstrudè vitès ak vitès pi wo a 300 r / min te parèt aletranje, kidonk anpil amelyore kapasite pwodiksyon an nan èkstrude la. Sepandan, pwoblèm tankou plastifye pòv yo pral pote sou apre ogmantasyon nan vitès la wotasyon, ki ankouraje moun yo etidye ak tès teyori a èkstruzyon ak vis estrikti. Kòm yon rezilta, anpil nouvo kalite vis parèt, tankou di ki kalite separasyon, kalite melanje, tip baryè, ak kalite chent, Konbinezon, elatriye rapò a aspè nan vis la te tou devlope soti nan 20: 1 rive nan 36: 1, kèk. kòm yon wo 43: 1. Sa a se trè efikas pou amelyore bon jan kalite a plastifikasyon ak efikasite.
(2) The auxiliary equipment of the extruder has also been perfected and standardized to meet the requirements of different plastic products.
(3) Extrusion automation, using microcomputer to detect and control the extruder process parameters, the temperature difference can be controlled within ± 1 ℃. The extrusion equipment adopts microelectronic technology to make the plastic extrusion molding process develop in the direction of accuracy, precision, energy saving and automation.
(4) Yo nan lòd yo satisfè kondisyon ki nan nouvo materyèl ak pwosesis nouvo, extruders nouvo oswa dedye yo toujou ap parèt. Tankou twa - èkstrudeur vis ak planetè mil - vis, vis - èkstrudeuz gratis, èkstrude reyaktif, de - èkstrude koulè, mousan extruder, elatriye.
Sèjousi, modèn plastik extrudeurs pelletizing yo jeneralman te adopte modèn teknoloji elektwonik ak òdinatè kontwòl pou pote sou - liy enspeksyon tout pwosesis EXTRUSION, ak adopte microchausses fèmen - bouk kontwòl. Yo nan lòd yo satisfè bezwen yo diversifiée nan devlopman pwodiksyon, plastik teknoloji bòdi devlope nan direksyon pou modèn efikas gwo - pwodiksyon echèl ak kontwòl entèlijan.
