Say injection molding machine screw et manunan kabiangan na makina, ya manunan uusaren ed pangiyakar, pangi-compact, panagtunaw, tan pangi-pressurize na saray plastik ya materyales. Say istruktura tan performance to et direktan mangaapekta ed inkaepektibo na panagplastik tan kalidad na produkto.
Say laman na tornilyo et tugyopen na feeding section, compression section, tan homogenization section. Say feeding section et responsable ed pangipainit tan pangiter na solidon raw materials; say compression section et makadampot na panagtunaw, panaglaok, tan panag-awit na dagem; tan say homogenization section et mangiseguro na parepareho na temperatura na natunaw tan inkapekder na agos. Base ed pandumaan na saray kalidad na plastik, saray tornilyo et nayarin i-categorize ed taloran klase: gradient type (matukoy ed saray materyales ya sensitibo ed petang a singa say PVC), abrupt type (matukoy parad polyolefins), tan general-purpose type. Say manunan pandumaan et walad karukey tan biskeg na desinyo na seksion na panag-ipit. Saray manunan parametro et kaiba so diametro, aspect ratio, tan compression ratio, ya kaukolan ya mipara ed saray kablian na materyal pian napaaligwas so epekto na panagplastik. Saray materyales ya mabetbet ya uusaren et saray materyales ya atagey-na temperatura tan ag-onkupas a singa say 38CrMoAla alloy tan tungsten carbide nickel-based alloy. Legan na panguusar, nakaukolan so estandartisadon proseso na preheating tan regular a panaglinis tan panagmintina pian ag-onlelereg so tornilyo odino naderal so makina.
