Ar antáirgí páirteanna múnlaithe insteallta, go háirithe na hamhábhair atá ABS, PP, PC, feicfidh tú go minic marcanna struis lonracha ar dhromchla an táirge, marcanna struis ejector, isteach sna marcanna strus fo, marcanna strus difríochta tiús flesh.
Tá na marcanna dealraitheacha lonracha agus bán seo mar thorthaí ar strus inmheánach, nach bhfuil níos mó ná strus treoshuímh agus strus crapadh fuaraithe. Is gnách go mbíonn marcanna struis neamhrialta in aice leis an geata mar thoradh ar strus treoshuímh, agus is é an difríocht tiús feola an toradh coitianta ar an treoshuíomh agus an strus crapadh, agus bíonn fachtóirí níos mó ag baint le bioráin ejector agus marcanna struis bioráin slant.
Go ginearálta, le méadú ar bhrú agus ar am, is é an chéad cheann marcanna strus difríocht tiús flesh, marcanna strus bioráin ejector, ansin marcanna strus difríocht tiús flesh, agus ar deireadh na marcanna strus neamhrialta in aice leis an geata (radharc taobh bán agus lonracha), ar ndóigh, braitheann sé freisin ar struchtúr sonrach an táirge agus suíomh an inlet.
Dá bhrí sin, nuair a bhíonn na marcanna strus seo le feiceáil, is é an brú sealbhaíochta agus an t-am sealbhaíochta an ceann is tábhachtaí a laghdú, agus é seo a thuiscint, ansin tosú as seo chun dearadh an táirge a mhodhnú agus tá dearadh múnla níos éifeachtaí ná coigeartú múnlaithe.
1. Dearadh táirge.
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. Dearadh múnla.
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. Coinníollacha múnlaithe.
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)
