Manufacturability Design and Engineering (DFM) – A team of custom molds and design engineers can work with your team to provide first-class component design support. […]
Concurrent engineering can significantly reduce mold design time while completing multiple design tasks. For example, one designer may work on the cavity side while the other works on the core side, […]
shallow side concave of plastic parts requires small core-pulling distance, yet when the molding area of side concave is large, a large core-pulling force is thereby needed, therefore, tilted lifter mechanism can be adopted for side parting and core-pulling. […]
a detail for designing tilted lifter mechanism need to be known, for inner side core-pulling, top of the tilted slide should be 0.05—0.1mm lower than the end plate if core, since during the protruding, […]
a suitable dip angle for designing a tilted lifter mechanism is very important, I think the pin’s dip angle B should be taken 5—25 degree ， […]
I have a tip for designing a tilted lifter mechanism, to endow the mechanism with restoration function, the length of circular bead for restoration should be adopted preferably larger under possible conditions, […]
therefore, shrinkage plays a more important part in the dimension of plastic parts when molding large parts, whereas when molding small parts, […]
abrasion loss during use. The abrasion and restoration during production can lessen the dimension of cores and enlarge the dimension of cavities.
manufacturing tolerance. The manufacturing tolerance directly influences the dimension tolerance of plastic parts, […]
the shrinkage of plastic parts, due to the nature of plastic ( to expand when hot and to shrink when cold), the dimension of plastic parts after molding and cooling is smaller than that of the cavity.
