Core

Definition

In the context of compression molding, the core refers to the central part or component around which the polymer material is shaped and formed. This element plays a crucial role in defining the final geometry of the molded part and can influence the mechanical properties and performance of the finished product. The core can be made from various materials and its design often accommodates specific requirements like heat distribution or strength.
