ʻO nā hiʻohiʻona nui o nā paipu kukui pololei:
ʻO ka paipu me ka pololei o ka paia, ka hoʻopau kiʻekiʻe, ka ʻaila oxide i mālama ʻole ʻia i ka wela, ka paia o loko o ke kila maʻemaʻe kiʻekiʻe e kū i ke kaomi kiʻekiʻe, ke anuanu deformation, flaring, flattening ʻaʻohe māwae, hiki ke hana i nā ʻano o ka deformation paʻakikī a me ka hana mechanical. . Ka waihoʻoluʻu paipu: keʻokeʻo me ka ʻālohilohi, me ka luster metala kiʻekiʻe.

ʻO nā kumu nui o nā paipu kukui pololei:
ʻO nā kaʻa, nā mīkini a me nā mea ʻē aʻe i hoʻohana ʻia no ka paipu kila pololei, hoʻopau i nā koi mechanical kiʻekiʻe. A i kēia manawa wale no nā mea hoʻohana o ka precision kila precision, hoʻopau kiʻekiʻe koi mea hoʻohana, a ma muli o ke kiʻekiʻe precision malamalama paipu precision tolerances hiki ke malama ma 2-8 uea, no laila, he nui machining mea hoʻohana e hoola i ka hana, mea, manawa poho, ka seamless kila. Hoʻololi mālie ʻia ka paipu a i ʻole ka pahu i paipu māmā pololei.
