What is the definition of “multi-cavity injection mold”?
Injection molds contain more than one cavity of the same shape. Multiple-cavity injection molds have a symmetrical layout, producing many parts of the same design.
Cavity Construction –Plastic Mold Making In China Design Basically, plastic mold making in the china cavity will be consist of a cavity main insert, and cavity insert, for this product. We use a cavity main insert shaped like a pin, and to release the air trap. We put a cavity insert pin (pink color) with gas vent land. Gate located at cavity main insert that one position with the parting line China Injection mold making process Cavities: 1, 2,4 to muti cavity up to 120 cavities mold Treatment: Pretreat, Heated to HRC 54, Or nitriding Mold Steel: Cavity, core, and slide; P20.2738.2312,2344, H13 available Standard: YUDO, DEM, HASCO, LKM Design Software: UG, PRO-E, SOLIDWORKS, AUTOCAD Why custom multi-cavity injection mold fill unevenly
The balanced filling is critical for making china plastic injection molding identical parts, achieving high CPKs, holding tight tolerances, and getting “good” data from the design of experiments.
We know for plastic injection moulding about the importance of uniform filling or balanced flow for each cavity of a multi-cavity mold. The balanced filling is critical for making identical parts, achieving high CPKs, holding tight tolerances, and getting “good” data from the design of experiments (DOEs). Balanced flow is critical for both filling and packing (filling influences packing).
