Weld kab (tseem hu ua Weld kab lossis cov kab sib xyaw ua ke los ntawm kev txhim kho kev ua kom zoo nkauj {}}
1.} Cov txheej txheem ua kom zoo
- Ua kom yaj kub txog qhov kub thiab txias: ntau dua kev txhim kho polymer fusion ntawm kev sib piv {}}}}}}} .
- txhawb kev txhaj tshuaj nrawm / siab ua kom tawg dua txias ua ntej kev sib ntsib ua ntej
- Txhawb nqa cov khoom siv kub: Tiv thaiv kev ua kom ntxov . kev sib tw wel6 2} {{% {{8}
2.}} Cov Khoom Npaj Npaj Thiab Hloov Kho
- Pre-Dry Polymers: Moisture >0 {{.} 05% ua rau muaj kev cuam tshuam weld uas tsis muaj zog weld interfaces}} g {}}}, tsiaj).
- Ntxiv cov kev txhim kho ntws: lubricants (e .} gucosity homogeneity kom tsis txhob txaus txaus {}}
- Xaiv cov txiaj ntsig tshaj plaws: amorphous polymers (e {{1} g}, AB) Vim li cas, pp) vim molecular diffusion .
3. Mould Tsim Kev Txhim Kho
- Rooj vag optimization:
- Relocate gates to ensure flow fronts meet at angles >135℃(tsim cov kab muaj zog meld es tsis txhob weld kab) .
- Siv cov kab hluav taws xob valve (SVG): tswj lub rooj vag ua ntu zus los ntawm kev ua piv txwv, SVG txo weld kab los ntawm 80% los ntawm synchronizing pem hauv ntej convergence.
- Txhim Kho Qhov Chaw: cuab cua ntawm Weld cov ntsiab lus inhibits fusion {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}
- Hloov kho phab ntsa tuab: tshem tawm txog kev hloov siab hloov ua kom txaus siab ua rau muaj kev kub ntxhov ntawm 1 . 5: 1).
4. Tshaj tawm cov kev tswj qhov kub thiab txias
- ** Thaum tshav kub kub lub voj voog kom nrawm (RHCM):
- Thaum tshav kub kub rau 120-150℃ua ntej kev txhaj tshuaj, tom qab ntawd txias nrawm.}}}} .
- Tsim nyog rau cov khoom loj (e {{2} g}}, tv be}, tv beld bezels), txo cov beld beltibility thiab nce zog los ntawm 40%.
- Induction Cua Sov: Tsis yog-planar coil reeped nthwv dej uniformly (e {degree) {.

- Meltflipper ™ thev naus laus zis: cov nyiaj sib piv kub viuxalees voltions nyob rau hauv ntau-kab noj pwm, ua kom symmetrical flow front.
6. kev tsim qauv-tsav tsim
Siv pwm los yog cov cuab yeej zoo sib xws rau:
- Kwv yees Weld Lej Thaj Chaw thiab Lub Zog (raws li kev sib dhos lub kaum sab xis thiab ntsuas kub) .
- Cov rooj sib tw kuaj qauv tsim / hloov chaw zoo ua ntej tooling {{1} Tus piv txwv: Lub lens pwm redesign txhij weld kab rau tsis yog-{3}
