Holoi Hoʻoheheʻe Māmā

Hana ʻia kēia wili hoʻoheheʻe lohi mai ke kila 38CrMoAla. He mea koʻikoʻi ka waiwai maka i ka hana ʻana, a koho mākou i ke kila ikaika a paʻa i ka ʻaʻahu mai nā mea hana kila Kina kaulana i kū i nā kūlana aupuni (GB/T 3077).

ʻO Nanhaiya's injection molding screw hiʻohiʻona i kahi ʻāpana hoʻopaʻa lōʻihi, maʻamau ma kahi o 50% o ka lōʻihi o ka lōʻihi. Ke emi mālie nei ka hohonu o ka ʻāwī wili mai ka ʻāpana hānai a i ka ʻāpana ana, e hōʻoia ana i ka lawe ʻana i ka plastic plastic, ka hoʻoemi, a me ka plasticization. He mālie ka hoʻololi ʻana o ka ikehu i ka wā o ka plasticization, a piʻi mālie ka hopena shearing i ka plastic i loko o ka wili, e hiki ai ke hoʻopau ʻia ke kaʻina hana plasticization ma lalo o nā kūlana haʻahaʻa.  

Ua loaʻa i nā ʻano R&D a me nā hoʻomaikaʻi hou ʻana o Nanhaiya i loko o nā laina hana o nā mea hana like ʻole, e loaʻa ana i ka hana kiʻekiʻe. Hāʻawi mākou i kahi palapala hōʻoia 1-2 makahiki, e pili ana i ka ratio hoʻohui mea kikoʻī. Hana ʻia nā barela o Nanhaiya i kahi kaʻina hana nitriding, me kahi papa mānoanoa 0.8 ~ 2m o ka nickel-tungsten alloy spray-welded ma nā wahi i hoʻopaʻa ʻia. Hoʻonui kēia i ka paʻakikī o ka pahu ʻo HRC55 ~ 62, e hoʻonui ana i ka pale ʻana i ka lole e 2-3 mau manawa.

ʻĀpana (Hōʻike)

Hiʻona a me ka noi

ʻO Nanhaiya's injection molding screw, me kāna ʻāpana hoʻopaʻa lōʻihi, loaʻa i ka "plasticization palupalu" o nā plastic amorphous a me ka wela. Ma o ka hoʻomehana lohi a me ka ʻohi hoʻomau, pale ia i ka hoʻohaʻahaʻa ʻana i nā mea ʻoiai e hōʻoiaʻiʻo ana i ka hoʻoheheʻe ʻana o ka hoʻoheheʻe ʻana, e kūpono loa ia no nā noi e koi ana i ke kūpaʻa plasticization kiʻekiʻe. He 40% -60% ka nui o ka lōʻihi o ka wili, ʻoi aku ka lōʻihi ma mua o nā wili hikiwawe (5% -15%) wale nō, e hāʻawi ana i kahi wahi hoʻololi no ka mea. Mai ke awāwa hohonu o ka ʻāpana hānai a hiki i ke awāwa pāpaʻu o ka ʻāpana ana, e emi mālie a hoʻomau ka hohonu, me ka ʻike ʻole ʻia o nā wahi hoʻololi "kōkō", no laila e pale ai i ka hoʻokaumaha nui ʻana o ka mea. Hoʻololi maʻalahi ka ʻāpana hānai a me ka ana ʻana ma o ka pauku hoʻopaʻa lōʻihi, e hana ana i kahi ʻano hoʻomau ʻoi aku ka hoʻomau ʻana o ka ʻāpana a me ka pale ʻana i ka hōʻiliʻili kūloko a i ʻole ka hoʻololi koke ʻana i ke kaomi i ka wā o ka lawe ʻana i nā mea.

He kūpono nā wili hoʻoheheʻe gradient no ka polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), polysulfone (PSU), a me ka resin ABS. Loaʻa i kēia mau plastics ka laula wela hoʻoluʻu ākea (e laʻa, PVC, ma kahi o 80-160°C) a i ʻole ke kūpaʻa wela maikaʻi ʻole (e laʻa, PC, hiki ke hoʻohaʻahaʻa ʻia i nā mahana ma mua o 300°C), e koi ana i kahi kaiapuni plasticizing mālie.

Nā kikoʻī huahana

ʻO ka hoʻomaʻamaʻa kiʻekiʻe, ka mīkini pololei, a me nā kaʻina hana nitriding e hōʻoia i ka hana piha o nā mea nui.

Hoʻoikaika ʻia nā wahi palupalu o ka screw a me ka barela me ka nickel-tungsten alloy layer, e loaʻa ana i kahi papa mānoanoa 0.8-2.0mm a hoʻomaikaʻi nui i ka pale ʻana i ka lole.
