Say panagproseso na plastik ya materyales et manunan proseso na panagtunaw, panag-agos tan panagpalemew na saray partikulo na goma pian magmaliw ya asumpal lan produkto kayari na pangi-set. Saya so proseso na panagpainit insan panagpalemew. Saya met so proseso na panguman na plastik manlapud saray partikulo ya anggad nanduruman kurti. Parad saray plastik ya thermoforming machine, say interon proseso et nayarin ipasadya parad full-automatic ya operasyon ya anggapoy manual ya operasyon, tan say kalidad na produkto et malet! Say onggendan so mangipaliwawa ed proseso na panagproseso manlapud panmoria na nanduruman yugtan.
1. Tunaw
Say heater na device et mamaabuloy ed saray partikulo na raw material ya kalkalnan natunaw pian magmaliw ya fluid flow. Saray nanduruman raw materials so manunan matukoy parad regulasyon na temperatura. Say pamarakep ed temperatura et mamapeles ed iyaagus na saray hilaw a materyales, ya nayarin mamarakep ed inkaepektibo, balet agmet seguradon naseguro so ani. Kaukolan ya nadampot so manepeg ya balanse. Niarum ni, say maong ya epekto tan saray katangian na PP no walay atagey ya thermal cracking et mas maabig no say raw material et onaagus ya maong ed die legan na produksyon, pian napaliisan so kulang ya filling odino reflux. Say reflux et mankabaliksan ya say iyaagus na raw material et mas maples nen say output rate, tan diad kaunoran et ondarakel so average flow efficiency, ya mipara ed inyaligwas na MFR. Sakey iya ed saray paraan na panagproseso, Balet, saya met so pansengegan na abnormal ya MFR distribution, ya nayarin pansengegan na lalon ag-inkayadyari tan lalon depekto. Balet, lapud aplikasyon, saray PP finished products et aliwan produkton walaan na atagey a dimensional precision, kanian aliwan baleg so epekto to.
2.Tornilyo so sanga
Maslak ed panagproseso na PP et mandedepende ed tornilyo ya mamaandar ed fluidity, kanian baleg so epekto na desinyo na tornilyo. Say diametro et mangaapekta ed output, tan say compression ratio et mangaapekta ed pressure value. Apektaen to met so epekto na output tan say asumpal a produkto, kaiba lay epekto na panlalaok na nanduruman materyales (Color Masterbatch, additives tan modifiers). Say iyaagus na saray hilaw a materyales et mandedependi ed heater, balet say pan-aagus tan pan-apag-apag na saray hilaw a materyales et mamawala met na friction heat energy pian napapeles so fluidity. Kanian, say screw compression ratio et melag, say agos et melag, tan say kapeles na panag-ikot to et kaukolan ya paeleten, kanian mas dakel so friction heat energy nen say screw ya baleg so compression ratio to. Kanian, mabetbet ya ibabaga ya anggapoy master ed panagproseso na plastik, tan say toon maalwar ya makatalos ed performance na makina et sikato so master. Say panagpainit ed saray hilaw ya materyales et aliwan sakey labat a pampainit, noagta kaiba met so petang na friction tan say panaon na pan-suffocate. Kanian, saya so praktikal a problema. Makatulong so eksperiensya pian nasolbar iray problema ed produksyon tan napaaligwas so inkaepektibo. No say epekto na panaglaok na tornilyo et maong, no maminsan et walay duaran yugtan ya nanduruman tornilyo odino biaxial ya tornilyo ya idesinyo, tan kada seksion na nanduruman klase na tornilyo et nibiig pian nawalaan na nanduruman epekto na panaglaok.
3. Ompatey o ompatey so ulo
Say pananguman na kurti na plastik et mandedepende ed mold odino die head. Say injection molding ya asumpal ya produkto et taloran dimension, tan say mold et komplikado met. Nepeg ya ikonsidera so problema ed panag-upot. Saray arum ya produkto et say plane, strip tan needle continuous product dies. No espisyal so kurti da, niklasipika iratan bilang espisyal ya kurti. Nepeg ya imanoen so problema na tampol ya panagpalemew tan panagsukat. Maslak ed saray plastik ya makina et singa saray hiringgilya. Say puersa na pangipaway na tornilyo et pansengegan na baleg a presyon ed melag ya outlet tan mamaaligwas ed inkaepektibo na produksyon. No say die head et adesinyo bilang sakey ya eroplano, no panon ya gawaen ya parepareho so inkaapag-apag na saray hilaw ya materyales ed interon tapew, say desinyo na die head na panagsabitan na kawes et importante. Imanoen so pankanawnawan man-extrude pian napalaknab so fish gill pump tan napabiskeg so suplay na raw materials.
4. Panagpaliis
Nilikud ed pangibubo na saray hilaw ya materyales ed sprue gate, say injection mold et walaan met na desinyo ya mamalemew na saray hilaw ya materyales diad cooling channel. Say extrusion molding et mandedependi ed cooling water channel ed roller pian nadampot so cooling effect. Niarum ni, wala met iray air knife, cooling water ya direktan inbasa ed blowing bag, hollow blowing tan arum niran paraan na panagpalamig.
5. Palaknaben
Say panproseso lamet tan pangilaknab ed asumpal a produkto so mamaaligwas ed epekto. Singa bilang, say pandumaan na kapeles na packing belt ya ipapaandar na saray roller ed arap tan beneg so pansengegan na extension effect. Say tensile force na extension part na asumpal a produkto et napabiskeg, ya aliwan mainomay ya nabuyak, balet ta mainomay ya nabuyak ya pabitay. Say inkaapag-apag na belat na molekula et mangapekta met ed epekto na panaglaknab ed maples a produksyon. Amin ya produkto ya in-extrude, kaiba lay fibers, et walaan na ag-inkaparaan ya kalaknab. Say vacuum tan compressed air forming et nayarin ipasen met ya sananey a klase na extension.
6. Manpaabeba
Antokaman ya raw material et walay problema tod shrinkage, ya sengegan na internal stress legan na thermal expansion, cold contraction tan crystallization. Diad inkalapagan, say thermal expansion tan cold shrinkage et mainomay ya natalonaan, ya nagawaan diad pamarukey na panaon na panagpabetel ed panagproseso tan pamasiansia ed pressure ya tuloytuloy. Saray kristalin raw materials et mas baleg so pandumaan na shrinkage da nen saray non crystalline raw materials, manga 16% parad PP, balet manga 4% labat parad ABS, ya midumaan a tuloy. Sayan parte et kaukolan ya nalampasan ed molde, odino saray additives pian nabawasan so shrinkage rate et mabetbet ya iyarum, say LDPE et mabetbet ya iyarum ed extrusion plate pian napaaligwas so problema ed necking.
Say plastik ya thermoforming machine et nayarin usaren ed ngalngalin amin ya thermoplastics. Diad agano niran taon, say plastic thermoforming machine et matalona met ya nausar pian makagawa na pigaran thermosetting ya plastik. Say siklo na panagmoldi na plastic thermoforming machine et antikey (pigaran segundo anggad pigaran minuto), tan sarag ton gawaen iray hulma ya komplikado so kurti, suston kabaleg tan diad sakey a panaon. Kaiba ed saray produkto na GTMSMART thermoforming machines Plastic Thermoforming Machine, Cup Thermoforming Machine, Plastic Vacuum Forming Machine, Plastic Flower Pot Thermoforming Machine.
GTMSMART mangiter na primeron klase na makina ed sankaabigan ya presyo ya mainomay ya makasumpal ed saray pankaukolan yo ed dakel a produksyon. Nengnengen so nanduruman produkto mi tan makaromog kayo na dakel ya high-performance ya opsyon ya matukoy ed saray pankaukolan yo.
