Hoʻokumu ʻia nā huahana ʻōpala ma ke ʻano hoʻohua kino a i ʻole kemika me ka lāʻau ma ke ʻano he kumu kumu no ka loaʻa ʻana o nā huahana like me ka sponge. Ua hoʻohana nui ʻia kēia ʻenehana i nā ʻoihana hana like ʻole, e like me nā puka kaʻa a me nā sila puka makani, nā cushioning pads, nā hale kūkulu hale, nā mea seismic, nā keʻena pale haʻuki, etc.

ʻO ka ʻōlelo maʻamau, pono e hoʻoheheʻe ʻia nā huahana i hoʻoheheʻe ʻia ma o ka mold e pili ana no ka hoʻoheheʻe ʻana, kahi huahana rubber ma hope o ke kiʻekiʻe wela, kiʻekiʻe kaomi vulcanization, mai ka mold cavity a i ʻole mold core ka mea maʻamau i ʻike ʻia he mold release. ʻO ka demolding maikaʻi ʻole kekahi o nā kumu koʻikoʻi no nā hemahema maikaʻi o nā huahana rubber a me ka hopena i ka hana pono. Hiki iā ia ke hoʻopōʻino e like me ka distortion a me ka haehae ʻana i nā ʻāpana, a ʻo kekahi hoʻi e hōʻino i ka ʻōpala, e hoʻopilikia i ka hana maʻamau. ʻO ke aʻo ʻana i nā mea maikaʻi ʻole e pili ana i ka demolding o nā huahana rubber he mea nui ia e hōʻoia i ka maikaʻi o nā huahana, pale i nā hemahema, pale aku i ka ʻōpala, a hoʻomaikaʻi i ka hana pono.

ʻO nā pilikia maikaʻi maʻamau a me nā hoʻonā ʻana i ka huʻa ʻana o ka lāʻau 1、ʻAʻole i lawa ka pua hū 2. ʻAʻole lawa ka hoʻopiha piha ʻana 3. ʻO nā lua huʻa ʻole (nui a liʻiliʻi paha) 4. over-vulcanization a i ʻole under-vulcanization
