Lub raj mis dej Preforms
Muaj PET Lub raj mis dej Preforms rau siab -Speed Stretch Tshuab Moulding
PET lub raj mis dej preforms yog precision txhaj-cov khoom nruab nrab molded ua tiav ntawm stretch tshuab moulding (SBM) rau hauv cov thawv nruj rau qhov tseem, sparkling, thiab ntxhia dej ntim. Tsim los ntawm cov khoom noj-qib nkauj xwb Polyethylene Terephthalate (PET) los yog tom qab- cov neeg siv khoom siv PET (rPET), cov preforms no tsim kom muaj kev ncaj ncees, lub caj dab tiav seal, thermal tolerance, thiab barrier zog ntawm lub raj mis zaum kawg.
Kev ua tau zoo nyob rau hauv siab -ceev rotary tshuab kab nyob ncaj nraim ntawm preform concentricity, qhov hnyav sib xws (+/- 0.2g kam rau ua), AA (Acetaldehyde) cov ntsiab lus tsuj, thiab cov phab ntsa tuab tuab. Tswj cov kev txwv no tiv thaiv phab ntsa thinning thaum lub sij hawm stretch ratio ntawm 8: 1 thiab 12: 1, tshem tawm kev nyuaj siab whitening, thiab tswj axial load zog thaum lub sij hawm siab - ceev palletizing thiab txias - sau los yog ambient filling ua haujlwm.
Txheem Tseem Dej Preforms (11g - 32g)
Optimized rau tseem ntxhia, purified, thiab caij nplooj ntoos hlav dej nyob rau hauv ntim ntawm 250 ml mus rau 2.0 L. Tsim nrog lub teeb yuag caj dab profiles kom txo tau cov khoom siv thaum tuav lub zog hoop nyob rau hauv ntsug load.
Carbonated Soft Drink (CSD) & Sparkling Water Preforms (28g - 52g)
Engineered nrog lub hauv paus hnyav dua, thicker sidewalls, thiab cov rooj vag tshwj xeeb tsim los tiv thaiv sab hauv siab txog 6-8 bar yam tsis muaj radial expansion lossis kev ntxhov siab tawg.
Loj -Format & Gallon Preforms (90g - 750g)
Tsim los rau 3-gallon, 5-gallon, thiab 10L txog 20L dej txias fwj. Muaj nyob rau hauv caj dab tiav txog li 55 hli (xov los yog caj dab-ntiv nplhaib snap-on), muab kev poob siab tsis kam thiab cov qauv nruj hauv qab qhov hnyav tag nrho.
High-Barrier / UV-Protected Preforms
Formulated nrog lub cev UV blockers los yog tshuaj lom neeg oxygen scavengers los tiv thaiv lub teeb degradation thiab tsw oxidation nyob rau hauv rhiab minerals los yog enriched dej.
Recycled PET (rPET) Preforms (25% txog 100% rPET Cov ntsiab lus)
Ua tiav siv GRS{0}}cov ntaub ntawv pov thawj rov ua dua tshiab los yog pellets. Formulated los khaws cia intrinsic viscosity (IV) theem (0.76 dl / g rau 0.84 dl / g) yam tsis ua rau lub qhov rooj crystallization los yog optical haze.
Yam khoom tseem ceeb
Ua tiav nrog cov chaw tswj qhov kub thiab txias thiab qis -shear screws kom AA qib qis dua 1.5 ppm, tiv thaiv tawm - saj hloov mus rau hauv lub raj mis tsis muaj ntxhiab.
Phab ntsa thickness variance tswj nyob rau hauv +/- 0.05 hli thiab qhov hnyav nyob rau hauv +/- 0.2g, kom ntseeg tau zoo ib yam stretch cua sov hla infrared qhov cub teeb.
Kub khiav valve- rooj vag tshuab ua kom lub tiaj tus, amorphous txhaj point nrog tsawg kawg nkaus lub rooj vag tail (< 0.5 mm), preventing base burst during high-pressure blowing (30–40 bar).
Precision-moulded sealing nto thiab threads tiv thaiv micro- leakage thaum lub sij hawm capping thiab roj poob nyob rau hauv daim ntaub ntawv sparkling.
Haze qhov tseem ceeb khaws cia qis dua 1.5% siv cov qib siab -qib resin thiab ceev txias - dej txias mus.
