To Jendalf: tool must be bigger than this hole :-)
Please check also diameter of machine nozzle and tool inlet. sometimes the splays can come from big shear, try to reduce injection speed. Please check also front of melt on short shot parts. If you...
hello, usualy the minimum mould dimensions are mentioned in machine drawings. If not, is there a rule, take a minimal distance between ejector holes on moving side and this is minimal toolsize - for...

Valve is not fully closed.

could you paste a photo of the part and injection gate position please?
also information about used material and if you made a filling study
It is a looooong time ago for me..... If I remember, inside are two halfmoons and the locking nuts are fixating the halfmoons in position. Halfmoons are connected by rubber O-ring. The screw is...
as usually 4 digits from hot-line phone number to KM Germany (it can be changed)
the base is to have a propper drying and proper process temeratures You have to still have in the brain, that the material contain FR aditives, which are sensitive for temperature. If FR aditive...
I fully agree with this. - very unusual
Please talk with your maintennce guy, how the screw hydraulic motor was replaced. I can imagine, that with reverse rotation the stucked tip can be released. I...
is not possible to move screw forward and take it out through barrel head?
