Zvishoma nezvishoma jekiseni Molding Screw

Iyi zvishoma nezvishoma jekiseni rekugadzira screw inogadzirwa kubva ku38CrMoAla simbi. Raw material yakakosha pakukora mashandiro, uye tinosarudza simbi yakasimba-yakasimba uye isingapfeki kubva kune vane mukurumbira vekuChina vanogadzira simbi inoenderana nemitemo yenyika (GB/T 3077).

Nanhaiya's zvishoma nezvishoma jekiseni rekuumba siruu rine chikamu chakareba chekuminyanisa, chinowanzoverengera chinosvika 50% yehurefu hwesiruu yese. Iyo kudzika kweiyo screw groove zvishoma nezvishoma inodzikira kubva pachikamu chekudyisa kuenda kuchikamu chemita, kuve nechokwadi chekutakura mapurasitiki akatsetseka, compression, uye plasticization. Shanduko yesimba panguva yepurasitiki yakapfava, uye kugerwa kwepurasitiki mukati me screw zvishoma nezvishoma kunowedzera, zvichiita kuti chirongwa chepurasitiki chipedzwe pasi pemamiriro akanyorova.  

Nanhaiya's zvishoma nezvishoma jekiseni rekuumba screw barrels dzakapfuura dzakawanda R&D uye kuvandudzwa uye zvino dzakabatanidzwa mumitsetse yekugadzira yakasiyana-siyana yevagadziri, kuwana mamiriro-e-the-art kuita. Isu tinopa 1-2 gore waranti, zvichienderana neiyo chaiyo yekuwedzera reshiyo. Madhiramu eNanhaiya anoita nitriding process, ane 0.8 ~ 2m gobvu layer yenickel-tungsten alloy spray-welded panzvimbo dzinonyanya kupfeka. Izvi zvinowedzera kuoma kwepamusoro kwebhari ndeye HRC55 ~ 62, inowedzera kupfeka kuramba ne2-3 nguva.

Feature uye Application

Nanhaiya's zvishoma nezvishoma jekiseni rekugadzira screw, ine chikamu chayo chakareba chekumanikidza, inowana "nyoro purasitiki" yemapurasitiki amorphous uye anonzwa kupisa. Kuburikidza nekudziisa zvishoma nezvishoma uye kuenderera mberi nekuveura, inodzivirira kuparara kwezvinhu uku ichisimbisa kunyunguduka, ichiita kuti ive yakanyatsokodzera zvikumbiro zvinoda kugadzikana kwepurasitiki. Chikamu chekumanikidza chinowanzo verengera 40% -60% yehurefu hwesikuru, kureba zvakanyanya kupfuura masiruu akangoerekana avapo (chete 5% -15%), ichipa nzvimbo yakakwana yekuchinja kwezvinhu. Kubva pakadzika groove yechikamu chekudya kusvika kune yakadzika groove ye metering chikamu, kudzika kunoderera zvishoma nezvishoma uye nekuenderera, pasina pachena "kamwe kamwe" shanduko yekuchinja, nokudaro kudzivirira kudzvinyirira kwakanyanya kwezvinhu. Zvikamu zvekudyisa uye zvemamita zvinosandura zvisina mutsetse kuburikidza nechikamu chakareba chekumanikidza, ichigadzira inoenderera mberi screw groove chimiro uye kudzivirira kuunganidzwa kwenzvimbo kana kungoerekana kushanduka shanduko panguva yekufambisa zvinhu.

Gradient jekiseni molding screws akakodzera rigid polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), polysulfone (PSU), uye ABS resin. Aya mapurasitiki angave ane hupamhi hwekunyorovesa tembiricha siyana (semuenzaniso, PVC, inosvika 80-160 ° C) kana kusagadzikana kwekushisa kwekushisa (semuenzaniso, PC, iyo inotapukira kushatisa pakupisa kunopfuura 300 ° C), inoda nzvimbo yakapfava yepurasitiki.

Product Details

Yepamberi tempering, chaiyo machining, uye nitriding maitiro anovimbisa kushanda kwakazara kwezvinhu zvakakosha.

Nzvimbo dzisina njodzi dze screw uye dhiramu dzakasimbiswa ne nickel-tungsten alloy layer, inowana 0.8-2.0mm gobvu layer uye zvakanyanya kunatsiridza kupfeka kuramba.
