Adverse factors of injection machine and product structure design affect injection filling
Adverse factors of injection machine and product structure design are in the following: […]
the eighth principle for deciding on the parting line is to consider the impact of draft
the eighth principle for deciding on the parting line is to consider the impact of draft. […]
design a right draft for your plastic part
as for draft, actually different parts have different requirement, a tall or larger plastic part design has a smaller draft, for a special need or higher precision requirement, […]
why some plastic parts are scratched?
during ejection, why some plastic parts are scratched? In order to answer this question, I need to introduce Draft to you. […]
how to add ribs to a plastic part design
but how to add ribs to a plastic part design, maybe there are something need to be considered: […]
the wall thickness of plastic part
the wall thickness of plastic parts is a very important parameter, because they often need to assembly with other parts, maybe plastic part or metal part and so on, so it needs to have sufficient strength for it’s application, […]
they affect the shrinkage of the plastic material
yes! You are right, as for affecting the shrinkage of the plastic material, I want to add something, the wall thickness and shape of plastic part also affect it’s shrinkage. For example, the plastic part with a thin wall shrinks less.
molding cycle
In order to achieve the shortest possible molding cycle, special cooling methods, added ejection features, special mold material and lubrication will be considered, on the other hand, some other elements may also have a significant impact on the molding cycle. For example Differences in the plastic, wall thicknesses, draft angles, methods of gating and so [...]
