Pulasitiki Injection Molding Screw Barrel Kapangidwe ndi Magwiridwe

Mitundu ya Mimbi: Bimetallic vs. Integral

Kusankha mbiya yoyenera kungapangitse kusiyana kwakukulu momwe aPulasitiki jakisoni womangira screw mbiyaamachita. Migolo ya Bimetallic imagwiritsa ntchito chitsulo cholimba chokhala ndi zitsulo zolimba mkati. Kapangidwe kameneka kamasunga zinthu zamtengo wapatali ndipo amalola opanga kuti alowe m'malo mwa nsalu yokhayokha, zomwe zimapangitsa kukonza kukhala kosavuta komanso kotsika mtengo. Kukwanira pakati pa mbiya ndi mbiya kuyenera kukhala kolondola kuti kutentha kuyende bwino komanso kupewa kuyenda. Migolo ya Bimetallic imagwira ntchito bwino pokonza mapulasitiki otsekemera kapena olimbikitsidwa chifukwa amakana kuvala komanso amakhala nthawi yayitali.

Migolo ya Integral imapangidwa ngati chidutswa chimodzi. Izi zimawapatsa kulondola kwambiri komanso ngakhale kugawa kwa kutentha pambiya. Amapangitsa kuti zikhale zosavuta kukhazikitsa ndi kusunga makina otenthetsera ndi ozizira. Komabe, amafunikira kuwongolera kokhazikika kopanga kuti akhalebe apamwamba. Poyerekeza ziwirizi, migolo yophatikizika imapereka chisamaliro chosavuta komanso kutentha kwa yunifolomu, pomwe migolo ya bimetallic imapereka kukana kovala bwino komanso kusinthika kwagawo kosavuta.

Migolo ya bimetallic nthawi zambiri imakhala nthawi yayitali kuposa migolo yophatikizika, makamaka ikakonza zida zolimba. Mapangidwe awo amachepetsa nthawi yocheperako komanso ndalama zosinthira, zomwe zimathandiza kuti kupanga kuyende bwino.

Screw Geometry: Ratio ya L/D, Compression Ratio, ndi Flight Design

Zithunzi za geometrywononga mkati mwa mbiya ya pulasitiki yopangira jekeseniamaumba momwe mapulasitiki amasungunuka ndi kusakanikirana. Chiŵerengero cha L / D, chomwe chimafanizira kutalika kwa wononga ndi m'mimba mwake, chimakhudza kusungunuka kofanana ndi kusakaniza. Zomangira zazitali (chiŵerengero cha L/D chapamwamba) chimapatsa pulasitiki nthawi yochulukirapo kuti isungunuke ndi kusakaniza, zomwe zimapangitsa kuti zinthu zikhale bwino. Komabe, ngati screwyo ndi yayitali kwambiri, imatha kuyambitsa kuwonongeka kwamafuta, makamaka ndi mapulasitiki osamva kutentha. Zida monga PVC ndi POM zimafunika zomangira zazifupi kuti zisawonongeke, pomwe mapulasitiki odzaza magalasi kapena owoneka bwino amapindula ndi zomangira zazitali komanso madera osakanikirana.

• Zida zokhazikika bwino zamatenthedwe zimagwiritsa ntchito zomangira zazitali kuti zisakanize bwino.
• Mapulasitiki osamva kutentha amafunikira zomangira zazifupi kapena ulusi wapadera.
• Zomangira zanthawi zonse (L/D ~20:1) zimagwirizana ndi mapulasitiki wamba koma zimatha kuwonetsa mitundu yosiyanasiyana.
• Zomangira zotchinga (L/D ~ 24:1) zimathandizira kusakanikirana kwa mapulasitiki olimba.
• Zomangira zolekanitsa (L/D ~18:1) zimathandizira zida zomwe sizimva kutentha kuti zisawonongeke.
• Zosakaniza zosakaniza (L/D ~ 22:1) zimapereka yunifolomu yosungunuka pamapulasitiki apadera.

Chiŵerengero cha kuponderezana chimayesa kuchuluka kwa wononga pulasitiki. Mapulasitiki apamwamba kwambiri amafunikira chiŵerengero chapamwamba cha kuponderezana kuti asungunuke ndi kusakaniza bwino. Kusintha chiŵerengero cha kuponderezana kumathandizira kulinganiza momwe zinthu zimayendera komanso mtundu wazinthu. Opanga nthawi zambiri amayang'anira ndi kukonza zomangira zomangira kuti zigwirizane ndi zosowa za zinthuzo.

Mapangidwe a ndege amafunikiranso. Zomangira zokongoletsedwa bwino bwino zimasungunuka bwino pofananiza ndi kayendedwe ka polima. Makina oyendetsedwa a Melt Delivery amathandizira kuwongolera kutentha ndi kukhuthala, kuchepetsa chiopsezo cha kuwonongeka.
