Along with the core and cavity placement, draft angles can also be used to keep the part on the right side of the mold. All these points contribute in one way or another to the placement of the core and cavity. Not only does everything need to fit together well to keep the process ...
PROBLEM TO BE SOLVED: To eliminate the warpage of a cavity side core by a temperature gradient during cooling and also as a change in the direction where a positioning pin and a core pin are fitted.;SOLUTION: In the mold assembly comprising the cavity side core and a movable side core, ...
An A-side (cavity) and B-side (core) of a mold are represented with the ejector plate and pins placed on the B-side. One of the goals of rapid injection molding is to produce parts quickly. Proper design helps ensure that good parts will be produced on the first run. Determining how...
5.46 which shows a simple core and cavity. When the part is molded, the shrinkage through the thickness of the part is frequently so low that when the mold opens, the outside of the molded part rubs against the cavity walls (shown in the figure with light shading). When texture is ...

If the mold design were reversed, the outside of the glass would shrink away from the cavity in the B-side and onto the core in the A-Side. The glass would release from the B-side and stick to the A-side where there are no ejector pins. At this...
Insufficient ultrasonic energy can only melt a small part of GF/PP pellets, and most GF/PP pellets are only bonded together in the mold cavity. At this time, there are clear pellet boundaries and large voids on the surface. Therefore, the microstructure of the mold core surface is not repl...
