Fa'ata'ita'i Blow Molded Product Design: Mai R Transitions to Material Selection

Talofa, sau e fa'atalanoa a matou oloa!

Folasaga ile Design
O oloa faʻapipiʻiina o loʻo faʻaaogaina lautele i pisinisi eseese, aemaise lava i totonu o meainu ma vailaʻau faʻapipiʻiina alamanuia, faʻapea foʻi ma pisinisi meataalo.

Fai le suiga R i pito ma tulimanu
E masani lava, o tulimanu ma tulimanu o le sasaina o oloa e tatau ona faia i le R suiga, aua o le tele o le faʻalauteleina o le fua faʻalautele i tulimanu maʻai e faigofie ona mafua ai le mafiafia o le puipui, ma o tulimanu maʻai e faigofie foi ona maua ai le taʻeina o le mamafa, ma le suiga R. o oloa e mafai ona faia le mafiafia puipui o oloa toniga.

Faʻateleina le faʻatulagaina o mamanu i le faʻamalosi, faʻalavelave ma le faʻalavelave
Faatasi ai ma manaoga eseese o oloa, e mafai foi ona faaopoopo nisi mamanu fausaga i le compression, tension ma torsion:

1. Afai e te manaʻo e faʻateleina le teteʻe umi o le oloa, e mafai ona e mamanuina nisi faʻamalosi i luga o le faʻalavelave faʻalavelave.
2. Ina ia faʻaleleia atili le faʻaogaina o le faʻaogaina o oloa, e mafai foi ona faʻatulagaina le pito i luga i se fausaga arc e faʻamalosia i le faʻamalosi ma faʻaopoopoina i le faʻamalosia o ivi.O le tauau o fagu oloa e tatau ona faʻafefe, e le mafolafola ma saʻo.

E masani lava, o le pito i lalo o le fagu e faia i se foliga concave e faʻateleina ai le malosi ma le faʻamautu.Mo se faʻataʻitaʻiga, e masani ona tatou vaʻai i fagu o loʻo i ai le suauʻu meaʻai ma nisi o foliga concave-convex i luga, lea e le gata ina faʻateleina ai le malosi o le tino fagu, ae faʻafaigofie foi le faʻailogaina o faʻailoga.

Mana'oga ma le fa'aofiina o mea e fa'afefeteina
O le atinaʻeina ma le faʻaogaina o tekinolosi faʻafefeteina e matua lautele lava, lea e fetaui lelei i le atinaʻeina o mea faʻapipiʻi.Ua faasolosolo malie ona atiaʻe mea faʻapipiʻi mai le uluai LDPE, PET, PP ma le PVC oloa e feulaina faʻainisinia palasitika, paʻu ma nisi mea tuʻufaʻatasia.

Manaoga faʻapitoa mo mea paʻu i vaega eseese o le palasitika feula
1. Extrusion blow molding
Extrusion blow molding o loʻo faʻatinoina i se tulaga tafe, ina ia faʻaitiitia le parison sag ma faʻamalieina le tufatufaina o le mafiafia o puipui, e masani ona faʻaaogaina le palasitika ma le mamafa mole mole tetele.

2. Suia tui
O le tui tui e faia i se tulaga maualuga.Ina ia faʻaitiitia le faʻaaogaina o le malosi o tui tui parison, o nisi palasitika e faigofie ona tafe (palasitika ma laʻititi mole mamafa) faʻaaogaina.

3. Su'i fa'alo'alo feula
Amorphous plastic e masani ona faʻaaogaina.Ona o le la'ititi la'ititi o le palasitika amorphous, e faigofie ai ona fa'aloloa.E ui lava o le PET e tioata foi, ae o le mea pito sili ona taua o le faʻaogaina o mea e faʻafefe ai, ma e fai si telegese le fua o le tioata.I se faapuupuuga, o le tele o le palasitika o le togiina o le sasa e feololo i le maualuga o le tufatufaina o le mamafa.

Ituaiga mea fa'a'u'u
1. Polyolefins

HDPE, LLDPE, LDPE, PP, EVA e masani ona faʻaaogaina mo le faʻafefeina o oloa gaosi oloa, koneteina ma meataalo meataalo, mea e teu ai vailaʻau, ma isi.

2. Thermoplastic polyester
PETG ma le PETP e masani ona faʻaaogaina mo le sasaina o fagu faʻapipiʻi mea inu carbonated ma fagu uaina, lea ua suia malie le PVC ma faʻaaogaina lautele.O le mea le lelei o le maualuga o latou tau, ma e masani ona faʻaaogaina mo le tui-tusi faʻafefe.

3. Inisinia palasitika (alloy)
ABS, SAN, PS, PA, POM, PMMA, PPO, ma isi ua faasolosolo malie ona faʻaaogaina i taavale, vailaʻau, meafale fale, vailaʻau vailaʻau ma isi pisinisi, aemaise lava le PC ma lona faʻafefiloi palasitika, lea e mafai ona faʻaaogaina e feula maualuga-grade koneteina ma oloa tau taavale (PC/ABS, ma isi).

4. Thermoplastic elastomer
E masani lava, o le SBS, SEBS, TPU, TPE ma isi mea fa'afefeteina e fa'aaogaina, a'o palasitika thermosetting, pa'u vulcanized ma crosslinked PE e le mafai ona feula.

Aotelega:
Mea masani mo tui tui

PE, PET, PVC, PP, PC ma le POM e masani ona faʻaaogaina mo koneteina ma vaega faʻavae e maualuga le saʻo ma le laʻititi laʻititi.
