I ka mahina o Mei, ua hele mai nā ʻenekinia o Grace i ka muliwai Nile nani e hoʻopau a holo i ʻelua laina hana paipu PVC 315-630mm. ʻO ka laina hana i loaʻa i kahi extruder māhoe-screw counter-rotating flat, kahi pahu pahu, kahi pahu spray, kahi tractor, kahi mīkini ʻoki, a me kahi mīkini lapalapa; ʻo ka ʻāpana he hana hilinaʻi a me ka hana kiʻekiʻe.

Hoʻolālā kūʻokoʻa ka counter-rotating flat twin-screw extruder a hoʻolālā ʻia e Grace i kahi hoʻolālā twin-screw hou, nona ka hopena plasticizing like ʻole e hōʻoia i ka hana paʻa o nā mea waiwai PVC i ka wā o ka hana ʻana; hiki i kahi pahu ho'ēmi kiʻekiʻe ke hōʻoia i ka hana paʻa o ka mea hoʻokipa; a ʻoi aku ka pololei o ka ʻōnaehana mālama wela; Hoʻomaopopo ka mana PLC i ka hana synchronous o ka mīkini holoʻokoʻa.

Hoʻohana ka pahu pahu i ka hoʻolālā wili paipu kiʻekiʻe a hiki ke hoʻololi ʻia ke kihi spray, ʻoi aku ka maikaʻi o ka hoʻoluʻu ʻana, hoʻomaʻamaʻa koke ʻia nā paipu paʻa i ka wahi mua; Hoʻokele ʻia ka tractor e kahi kaʻa servo, paʻa a hilinaʻi ka traction, a haʻahaʻa ka walaʻau; ʻO ka mīkini ʻoki honua hou, hilinaʻi a paʻa, ka hopena suction chip maikaʻi, haʻahaʻa haʻahaʻa; Hoʻohana ka mīkini flaring i ka mana PLC, me ka hoʻomehana maikaʻi a me ka hoʻomaha.

Me ka hoʻoikaika mau ʻana e uhaki i nā pale, ua loaʻa iā Grace kekahi mau laina paipu e holo ana i nā hale kūʻai aku ma ʻAigupita, a ʻo ka manaʻo mai nā mea kūʻai aku he maikaʻi loa ia, a ua loaʻa i kahi māhele mākeke a me ka inoa maikaʻi. Ke nānā nei i ka wā e hiki mai ana, e holomua ana ʻo Grace a lilo i mea hōʻailona hou no Made in China ma ʻAigupita a me ka Middle East a me ʻApelika ʻĀkau me nā huahana kiʻekiʻe, nā lawelawe kūpono a me ka hoʻomau mau.
