you mean in mold labeling? we also make such mold for container. the process is to insert a label to mold cavity, the label will be static charged to stick to mold surface.
to sucess the process, product design is very important, must consider the flow of plastic, flow direction can't shift the...
Dear Pud,the material is PS. Mold core steel is H13,HRC 50.
Dear Pat, you're right for long thin mold, this kind of deflection happens all the time. It also happens on muti-cavity thin-wall container. ex. a 4 cavity thin-wall cup, mold core will always tilt toward the center of mold plate...
Dear Pat,
yes, the plate thickness is very important. Some of our mold core support plate can be over 120mm....
attached is another sample of mold. you can see mold deflection in the middle area.
we can adjust by machining the support plate or by putting some thin copper sheet in the middle...
Hi,
we're designing a 4 cavity thin-wall cup, but we face the problem of mold base deflection. the middle of mold plate(male side) will sink by injection pressure and cause uneven wall-thickness. When mold base sink, mold cores will move toward the center.
we have to put few thin copper sheet...
