Nyob ntawmtxhaj tshuaj molded qhov khoom, tshwj xeeb tshaj yog cov ntaub ntawv raw yog ABS, PP, PC, feem ntau koj yuav pom ci ntsa iab cov cim kev nyuaj siab ntawm cov khoom, ejector cov cim kev ntxhov siab, rau hauv cov cim kev ntxhov siab, cov nqaij tuab qhov sib txawv ntawm qhov kev ntxhov siab.
Cov cim ci ntsa iab thiab dawb no yog cov txiaj ntsig ntawm kev ntxhov siab sab hauv, uas tsis muaj ntau tshaj li kev xav txog kev ntxhov siab thiab kev ntxhov siab txias. Cov cim kev ntxhov siab tsis tu ncua nyob ze ntawm lub rooj vag feem ntau tshwm sim los ntawm kev taw qhia kev ntxhov siab, thaum lub cev nqaij daim tawv sib txawv yog qhov tshwm sim ntawm kev taw qhia thiab kev ntxhov siab, thaum lub ejector tus pin thiab slant tus pin kev ntxhov siab yog tsim los ntawm ntau yam.
Feem ntau, nrog kev nce siab thiab lub sijhawm, thawj tus yog cov cim kev ntxhov siab ntawm cov nqaij tawv tuab sib txawv, cov cim kev ntxhov siab ntawm ejector tus pin, tom qab ntawd cov cim kev ntxhov siab ntawm cov nqaij tuab sib txawv, thiab thaum kawg qhov kev ntxhov siab tsis xwm yeem nyob ze ntawm lub rooj vag (sab saib yuav dawb thiab ci), tau kawg, nws kuj nyob ntawm cov qauv tshwj xeeb ntawm cov khoom thiab qhov chaw ntawm qhov nkag.
Yog li ntawd, thaum cov kev ntxhov siab no tshwm sim, txo qhov tuav tuav thiab tuav lub sij hawm yog qhov tseem ceeb tshaj plaws, thiab kev nkag siab txog qhov no, ces pib los ntawm qhov no los hloov cov khoom tsim thiab pwm tsim tau zoo dua li kev hloov molding.
1. Cov khoom tsim.
The overall meat thickness is too thin or flowing end meat thickness is thicker leading to filling pressure and holding pressure is too large, need to add glue or flowing end steal meat. That is to say, when the holding pressure is reduced, see if the shrinkage can steal meat to improve, if not, it is necessary to add glue on the large side.
Try to avoid poor meat thickness, if there is a need to do a large differentiation.
The rib of the male mold to avoid doing too big leads to the mother mold having rib stress marks.
2. Pwm tsim.
Gates are too small or the number is too small and unevenly distributed.
The movable parts with loose mold or unreasonable waterway configuration lead to high mold temperature.
3. Pwm tej yam kev mob.
The reasonable setting of holding pressure and time (lower).
Increase or decrease the mold temperature (increase can improve the filling and reduce the pressure; decrease is to make the surface shiny, the surface and stress marks close, generally speaking, reduce the mold temperature is the majority of options)
