I ke kūkulu ʻana a me ka hana ʻana i nā ʻoihana hoʻopaʻa paʻa i ʻelua mau mea nui loa:

• Hoʻomau - pehea ka lōʻihi o ka lōʻihi o kaʻu mea hoʻopaʻa i kahi kaiapuni?
• Efficiency - pehea ka wikiwiki e hiki ai iaʻu ke hoʻopaʻa iā ia?
• ʻO kahi mea hoʻololi pāʻani ma ka ʻoihana hoʻopaʻa ʻana ʻo ia ka mea i hana ʻia i nā wili hoʻoheheʻe ponoʻī, i hoʻopōkole i nā kaʻina hana i nā lōʻihi loa.Eia naʻe, ʻaʻole hiki ke hoʻopaʻakikī ʻia nā wili kila kila ʻole AISI 300, ʻo nā mea hiki ke hana i nā wili selfdrilling me nā kiko drill paʻakikī no ka wili ʻana i ke kila ua kaupalena ʻia i nā mea paʻa i hana ʻia mai ke kila.

• HOOMAIKAI No nā makahiki he ʻumi, ua manaʻo ʻia ʻo AISI 304 a me AISI 316 Austenitic Stainless Steel ka mea mua, poʻokela a wale nō i koho ʻia ma ʻAmelika ʻĀkau no ka hoʻohana ʻana i waho ma kahi ʻano paʻakikī; kahakai a me nā wahi ʻoihana, etc.ʻO ka maikaʻi o ka Austenitic Stainless Steel i loko o Chromium a me Nickel a me Molybdenum no AISI 316 he mau hana corrosion maikaʻi loa a ma ka manawa like me ka ductile loa me ka pilikia ʻole o ka Hydrogen Assisted Stress Corrosion Cracking (HASCC) a i ʻike ʻia ʻo Hydrogen Embrittlement.

  Ua hoʻomohala ʻo DD Fasteners i nā ʻenehana forging anu kūpono e hoʻokō i kahi kaʻina hana hana maikaʻi me ka maikaʻi o ka huahana kiʻekiʻe me nā keʻena paʻi maikaʻi no ka hoʻopaʻa ʻana iā ia iho, e like me ka maʻamau #1/4 -1-3/4” me 3/8” poʻo me kekahi. he AISI 304 a i ʻole AISI 316 kila kila EPDM i hoʻohui ʻia.

• E noho mālie, hauʻoli
  ʻO mākou ʻo DD Fasteners China, mea hana screw, kā mākou i ka hana ʻana i nā huahana screw professional no nā makahiki he 20, loaʻa iā mākou nā lawelawe OEM no nā hōʻailona kūloko ma ka Hikina Hikina, a ʻike nui ʻia e ka mea kūʻai mai nā wahi a pau o ka honua.Pūnaewele:
