Nui nā ala e hiki ai pa?i ki?i ma ka metala:

1. Pa?i siliki a pa?i pa?i: Inā nui a palahalaha ka wahi, hiki iā ?oe ke ho?ohana i ka pale silika a me ka pa?i pa?i pa?i, akā ho?okahi ke kala o ka pa?i ho?okahi, a ?a?ole hiki i ka pa?i pale ke pa?i i nā kala maika?i loa a pa?akikī. He ki?eki?e loa ke kumukū?ai kala piha. Ke ho?ohālikelike ?ia me ka pa?i pale, hiki ke pa?i i nā huahana me nā koi kala mālie.

2. Pa?i pa?i: ?a?ole ?oko?a loa ka hopena mai ka pa?i pale, kūpono no ka curved, curved, concave a convex surfaces a me nā huahana pākahi hiki ?ole ke pa?i ?ia.

3. ?O ke kalai ?ana i ka laser lolouila a i ?ole ke kalai ?ana: Hiki i ke kahakaha laser ke hana i nā kikokikona maika?i a me nā laina, akā ?a?ole hiki ke hana i nā ?ano kala. ?O ke kala ke?oke?o a hinahina wale nō. ?Oi aku ka maika?i o ka hopena o ka etching ma mua o ke kahakaha ?ana o ka lolouila, a ?a?ole maika?i loa. Inā makemake ?oe i ke kala, pono ?oe e kala ka?awale.

4. UV ink jet: Inā palahalaha a ma?ema?e ka ?ili a nui ka wahi, hiki iā ?oe ke hana i ka UV ink jet, e ho?opu?i i nā ?ano kala ma luna o ka pā metala, ua like ka hopena me ka ink jet, inā ?a?ole ki?eki?e nā koi. hiki iā ?oe ke hana i nā ki?i a i ?ole ka?a ka?a, a ho?opili pololei ma ka ?ili metala , ?O kēia ala ke kumu kū?ai ha?aha?a loa.
