High Efficiency 4 Cavities Medical Treatment Die Steel Mold Core for Lab Petri Dish Plastic Mold Parts

The mold core plate forms the interior of the final plastic part. Similar to the cavity, the mold core can be positioned on either plate. For complex parts such as medical injection molding products, a loose mold core insert may be required. These inserts are removed from the mold at the end of each cycle, and the part is then extracted from the insert.

By convention, the hollow (concave) portion of the cavity space is called the cavity, while the matching, often raised (convex) portion is called the mold core. Most plastic products are cup-shaped, meaning they have distinct inside and outside surfaces. The outside is formed by the cavity, and the inside by the mold core. Flat-shaped products without specific convex portions present different molding challenges, particularly for ejection. Typically, cavities are placed in the injection side mold half, while cores are positioned in the moving half to facilitate ejection.
