Yakawandisa particle saizi yezvakagadzirwa zvinoderedza particle size
14
Iyo screw yemuchina wekuumba jekiseni haigone kutenderera
Tafura 14 inoratidza zvikonzero zvinogoneka uye nzira dzekurapa dzekusakwanisa kwe screw kutenderera
Nzira dzekugadzirisa zvikonzero zvekuitika
Low melt tembiricha inowedzera tembiricha yekunyungudika
Kuwedzeredza kumashure kudzvinyirira kunoderedza kumashure
Kusakwana kwekuzora kwe screw uye kwakakodzera kuwedzera kwe lubricant
15
Material leak kubva mujekiseni nozzle yemuchina wekuumba jekiseni
Tafura 15 inoratidza zvinogona kukonzera uye nzira dzekurapa dzejekiseni nozzle kuvuza
Nzira dzekugadzirisa zvikonzero zvekuitika
Kunyanya kupisa kwepombi yezvinhu kunoderedza kutonhora kwepombi yezvinhu, kunyanya muchikamu chenozzle
Kugadziriswa kusina kunaka kwekumanikidzwa kwemashure uye kuderedzwa kwakakodzera kwekumanikidzwa kwemashure uye screw speed
Main chiteshi inotonhora zvinhu zvekubvisa nguva yekutanga kunonoka kutonhora zvinhu zvekubvisa nguva
Kusakwana kuburitsa nzendo kuwedzera nguva yekuburitsa, kushandura nozzle dhizaini
16
Nyaya yacho haina kunyungudika zvachose
Tafura 16 inoratidza zvinogona kukonzera uye nzira dzekurapa dzekunyungudika kusina kukwana kwezvinhu
Nzira dzekugadzirisa zvikonzero zvekuitika
Low melt tembiricha inowedzera tembiricha yekunyungudika
Low back pressure inowedzera musana
Chikamu chezasi chehopper chinotonhora zvakanyanya. Vhara chikamu chezasi chehopper cooling system
Short molding cycle inowedzera kuumbwa kutenderera
Kusakwana kuomeswa kwezvinhu, kunyatsobika kwezvinhu
