Ongororo yezvinokonzeresa warpage uye deformation yejekiseni yakaumbwa zvigadzirwa:
1. Mold:
(1) Ukobvu uye kunaka kwezvikamu zvinofanira kunge zvakafanana.
(2) Dhizaini yegadziriro yekutonhodza inofanirwa kuita tembiricha yechikamu chega chega chegomba yunifomu, uye sisitimu yekudurura inofanirwa kuita kuti zvinhu zviyerere symmetrical kudzivirira kuputika nekuda kwekusiyana kwekuyerera uye shrinkage rates, uye zvakakodzera gobvu vanomhanya uye. mainstream of the hard-to-form parts.Mugwagwa, edza kubvisa density mutsauko, kudzvanywa musiyano, uye tembiricha musiyano mugomba.
(3) Nzvimbo yekushandura uye makona ehukobvu hwechikamu inofanira kunge yakatsetseka zvakakwana uye iine yakanaka mold kuburitswa.Semuenzaniso, wedzera iyo mold yekuburitsa margin, kunatsiridza kukwenenzverwa kweiyo mold pamusoro, uye chengetedza kuenzana kweiyo ejection system.
(4)Kupera kwakanaka.
(5) Wedzera kukora kwemadziro echikamu kana kuwedzera kutungamira kwekurwisa-warping, uye simbisa iyo anti-warping kugona kwechikamu nekusimbisa mbabvu.
(6)Kusimba kwechinhu chakashandiswa mukuumbwa hakuna kukwana.
2. Plastic chimiro:
Crystalline mapurasitiki ane mikana yakawanda ye warping deformation pane amorphous mapurasitiki.Mukuwedzera, mapurasitiki ekristalline anogona kushandisa crystallization process yecrystallinity kuderera nekuwedzera kwekutonhora uye shrinkage rate kugadzirisa warpage.
3. Maitiro ekugadzirisa:
(1) Kudzvanywa kwejekiseni kwakanyanyisa, nguva yekubata yakarebesa, uye tembiricha yekunyunguduka yakadzikira uye kumhanya kwakakurumidza, izvo zvichaita kuti kushushikana kwemukati kuwedzere uye warp deformation.
(2) Tembiricha yekuumbwa yakakwira zvakanyanya uye nguva yekutonhora ipfupi, izvo zvinozoita kuti chikamu chibviswe nekuda kwekupisa panguva yekudonha.
(3) Deredza screw kumhanya uye kumashure kumanikidza kudzikisa density uchichengeta hushoma hwekuzadza huwandu kudzikamisa chizvarwa chekushushikana kwemukati.
(4) Kana zvichidikanwa, mativi anokombamira kukombama uye deformation anogona kuva akapfava-kuumbwa kana kugadzirwa obva adzorerwa.
