Joalo ka moetsi oa hlobo o rekisetsang kantle naheng ea China, Ha a bapisoa le hlobo ea lapeng, litheko tsa hlobo tsa kantle ho naha li phahame haholo lilemong tse fetileng, lekhalo le bakoa ke maemo a diffriend. American Society of Plastic Industry (SPIAN-102-78) e arola hlobo ka mekhahlelo e mehlano. Mefuta ena e mehlano ea hlobo e na le litlhoko tse fapaneng, 'me maemo a ho khetholla a sebetsa feela ho tsamaisana le mochini oa ente o qobellang lithane tse ka tlase ho 400.
Linako tsa potoloho ea bophelo ho fihlela makhetlo a limilione tse 1, tse khethehileng bakeng sa bokhoni bo phahameng ba tlhahiso ea sehlahisoa. Ho khetha tšepe ea hlobo e ntle ka ho fetisisa ho e etsa, e tsamaellanang le hlobo ea sehlopha sena e hloka theko e phahameng ka ho fetisisa. Litlhoko li bontšoa ka tsela e latelang:
(1) Ho hlokahala ho ba le lintlha tse qaqileng tsa sebopeho sa hlobo.
(2) Litlhoko tsa ho thatafala ha hlobo bonyane BHN280 (HRC30).
(3) Sebaka sa hlobo (ho kenyeletsoa li-cavity le li-molds tsa mantlha) bonyane ka har'a mefuta e thata ea BHN450 (48HRC), lisebelisoa tse ling tsohle tse kang li-slider, lifters, lifters tse otlolohileng, joalo-joalo li lokela ho ba thata.
(4) Tsamaiso ea ejection e tla ba le tsamaiso ea tataiso.
