He aha ke kūlana aupuni no ka nui o ka hoʻomanawanui ʻana o nā ʻāpana injection kaʻa?
ʻO ke kūlana aupuni no ka nui o ka hoʻomanawanui ʻana o nā ʻāpana injection automotive ʻo GB / T 14486-2008 "Plastic molded Parts Size Tolerance".Hōʻike kēia maʻamau i ka hoʻomanawanui dimensional o nā ʻāpana i hoʻoheheʻe ʻia, a kūpono i nā ʻāpana i hoʻoheheʻe ʻia i hoʻopili ʻia, paʻi ʻia a hoʻopaʻa ʻia.
Wahi a ke kūlana aupuni, ua hoʻokaʻawale ʻia ka nui o ka hoʻomanawanui ʻana o nā ʻāpana injection automotive i nā māka A a me B.He kiʻekiʻe nā koi pololei o ka papa A, kūpono no nā ʻāpana injection precision;He haʻahaʻa nā koi pololei o ka papa B, kūpono no nā ʻāpana injection maʻamau.ʻO ka laulā hoʻomanawanui kikoʻī penei:
(1) Linear dimensional tolerance:
ʻO nā ana laina e pili ana i nā ana ma ka lōʻihi.No ka papa A i hoʻoheheʻe ʻia i nā ʻāpana, ʻo ka nui o ke ahonui o ka laina laina he ± 0.1% a ± 0.2%;No nā ʻāpana i hoʻoheheʻe ʻia i ka papa B, ʻo ka pae hoʻomanawanui no nā ana laina he ± 0.2% a ± 0.3%.
(2) ʻO ka ʻae ʻana i ka huina:
ʻO ka ʻae ʻae ʻana e pili ana i ka ʻae ʻana o ka Angle ma ke ʻano a me ke kūpaʻa kūlana.No ka papa A injection molded parts, the Angle tolerance is ±0.2° to ±0.3°;No ka papa B injection molded parts, the Angle tolerance is ±0.3° to ±0.5°.
(3) Ke ʻano a me ke kūlana kūlana:
ʻO ke ʻano a me ke kūlana kūlana e like me ka poepoe, cylindricity, parallelism, verticality, etc. No ka papa A injection, hāʻawi ʻia ke ʻano a me ke kūlana kūlana e like me ka papa K ma GB/T 1184-1996 "Shape and Position Tolerances not specified Tolerance Value";No ka papa B injection, hāʻawi ʻia ke ʻano a me ke kūlana kūlana e like me ka papa M ma GB/T 1184-1996.
(4) 'Oka 'ilikai:
ʻO ka ʻeleʻele o ka ʻili e pili ana i ke ʻano o ka microscopic unevenness ma ka ʻili mīkini.No ka papa A injection molded parts, the surface roughness is Ra≤0.8μm;No ka papa B injection molded parts, the surface roughness is Ra≤1.2μm.
Eia kekahi, no kekahi mau koi kūikawā o nā ʻāpana injection automotive, e like me nā panels instrument, center console, a me nā mea ʻē aʻe, ʻoi aku ka kiʻekiʻe o nā koi hoʻomanawanui dimensional, a pono e hoʻomalu ʻia e like me nā koi huahana kikoʻī.
I ka pōkole, ʻo ke kūlana aupuni no ka laulā o ka dimensional tolerance o nā ʻāpana injection automotive he GB / T 14486-2008 "Dimensional tolerance of Plastic molded parts", e kuhikuhi ana i nā koi o ka dimensional tolerance, shape and position tolerance and surface roughness of plastic molded. ʻāpana.I ka hana maoli, pono ia e hoʻoponopono a hoʻopaʻa pono e like me nā koi o ka huahana a me ka hoʻolālā mold e hōʻoia i ka hoʻokō ʻana o nā ʻāpana injection i nā koi.
