1. Lisosa tsa keketseho ea litšenyehelo tsa ho lahla foam
Keketseho ea litšenyehelo tsa ho lahlela foam e lahlehileng haholo-holo e tsoa likarolong tse peli: mohlala oa foam le tšebeliso ea pente. Tone e 'ngoe le e' ngoe ea ho lahlela e ja ligrama tse 3000 tsa mofuta oa foam (ho kenyeletsoa le riser e tšelang). Haeba u iketsetsa mofuta oa foam, litšenyehelo ka gram ke 0.02RMB. Ke hore, mofuta oa foam o ja 60RMB ka tone; haeba mohlala oa foam o rekoa, hape ke 0.03 ~ 0.05RMB ka gram. Ka mantsoe a mang, e ja 90-150RMB ka lithane tsa castings. Lipente kaofela li iketselitse, theko ea kakaretso e pakeng tsa 500-1000RMB, 'me palo ea lisebelisoa tse ling e fokotsehile, e baloa ho 1000RMB ka tonne ea pente e omileng ea phofo, esita le bakeng sa likarolo tse tšesaane tse nang le marako, e ka ja 50-60 feela. lik'hilograma ka tone, ke hore, ha ho na ho feta 100RMB. Ka hona, litšenyehelo tsa ho lahlela foam tse lahlehileng lia eketseha, tse ka hlalosoang e le:- ①Moetso oa foam o entsoeng hae: hoo e ka bang 160RMB; (liphetoho le 'maraka)
