Pa intaneti kapena kutsegulidwa kwaintaneti pakuwonjezera mapampu
Kulemba kumbuyo kwa makina owumba kumatha kuyambitsa kuzungulira kwa chizindikiro, chifukwa cha botolo la botolo. Pali njira zingapo zakusintha / kuthetsa mavutowa.

The zida zofunikira zimatengera kwambiri zida zomwe zimagwiritsidwa ntchito (mtundu wa pulasitiki, masterbatch, etc ...) ndi botolo geometry. Kuchepetsa parison kumawonjezera shrinkage komanso. Kukula kwakukulu kwa parison, kumachepera zinthuzo zikafalikira mukamaphulika motero kumachepetsa mabotolowo. Shrinkage imatha kuchitika mpaka maola 72 ataphulika botolo!
The kulembera makulidwe ndikofunikira, makulidwe, akapanda kulembera, ochepera ndiye mwayi wokhala makulidwe pabwino.
The guluu wamagwiritsidwe ntchito pa chizindikiro ndikofunikira. Pali magalasi enaake, omwe amalola kuti lilembe lisunthike, motero kulipirira mphamvu ya shrinkage.
The zilembani zinthu imakhudzanso shrinkage, mitundu yosiyanasiyana yomwe ilipo, pepala, pulasitiki, pomwe iyi yomaliza ilinso ndi mwayi pobwezeretsanso, malingana ngati ndi zinthu zomwezo.
Zolemba za pulasitiki zimakonda kukhala ndi 'shrinkage' bwino kuposa zolembera zapepala.
