Nzọụkwụ Usoro Lamination Key

1. Nkwadebe ihe eji eme ihe: Họrọ pellets plastik kwesịrị ekwesị (dịka, PE, PP, PLA) na ihe ndị ọzọ (dịka ọmụmaatụ, akwụkwọ na-amaghị nwoke, akwa na-abụghị akwa).

2. Na-agbaze Plastic na Extrusion: A na-etinye pellets plastik n'ime onye na-apụ apụ, ebe a na-agbaze ha n'ime mmiri viscous na okpomọkụ dị elu. A na-esizi na T-die pụpụ plastik a wụrụ awụ ka ọ bụrụ otu ihe nkiri gbazere.

3. Mkpuchi na Mgbakọta: Ihe nkiri rọba a wụrụ awụ na-ekpuchi ya nke ọma n'elu mkpụrụ osisi a na-enwebeghị ọnya n'okpuru nchịkwa esemokwu. N'ebe mkpuchi ahụ, plastik a wụrụ awụ na mkpụrụ ahụ na-ejikọta ọnụ n'okpuru ọrụ nke rollers nrụgide.

4. Ntu oyi na Ntọala: Ihe mgbagwoju anya na-agafe ngwa ngwa site na rollers jụrụ oyi, na-ekwe ka oyi akwa plastik a wụrụ awụ mee ngwa ngwa dị jụụ ma sie ike, na-eme ihe nkiri plastik siri ike.

5. Ikuku: The mma na ịtọ laminated mejupụtara ihe na-emerụ n'ime mpịakọta maka ụdi nhazi na ojiji.
