ʻO Kina OEM maʻamau i hoʻolei ʻia ke kila kalaponanā huahana hoʻoheheʻe ʻia ʻana o ka pūpū.
Ka hoʻoheheʻe ʻia ʻana o ka pūpūUa kapa ʻia ke kaʻina hana hoʻoheheʻe ʻana i ke one resin pre-coated, nā hoʻoheheʻe ʻana i ka pūpū wela a i ʻole ke kaʻina hoʻolei kumu. ʻO ka mea hoʻoheheʻe nui ka one phenolic resin pre-coated, ʻoi aku ka maikaʻi ma mua o ke one ʻōmaʻomaʻo a me ke one furan resin. Eia kekahi, ʻaʻole hiki ke hoʻohana hou ʻia kēia one.
ʻO ke kaʻina hoʻolei one paʻakikī paʻakikī Furan resin (nobake process) hoʻohana i ke one i uhi ʻia i ka furan resin e hana i ka mold. Ma hope o ka hui ʻana i ke one kumu (a i ʻole ke one i hoʻihoʻi ʻia), ka wai furan resin a me ka catalyst wai me ka like, a hoʻopiha iā lākou i loko o ka pahu kumu (a i ʻole pahu one), a laila e hoʻopaʻa i ka paʻakikī i loko o kahi ʻōpala a i ʻole i loko o ka pahu kumu (a i ʻole ke one. pahu) ma ka lumi wela. A laila ua hoʻokumu ʻia ka pahu hoʻoheheʻe a i ʻole ka hoʻoheheʻe ʻana i ke kumu, i kapa ʻia ʻo ia hoʻi ka paʻakikī paʻakikī paʻakikī pahu pahu (core), a i ʻole ke ʻano hana paʻakikī (core).
No ka mea, ua hoʻokumu ʻia ka mold i ka lumi wela a ʻaʻole pono e wela, ua kapa ʻia ka hoʻolei ʻana i ke one paʻakikī ponoʻī. Hiki ke hoʻokaʻawale ʻia ke ʻano paʻakikī paʻakikī i loko o ka acid-catalyzed furan resin a me ka phenolic resin sand self-hardening method, urethane resin sand self-hardening method and phenolic monoester self-hardening method.
