What is Core Insertion? Core insertion refers to placing the core into the mold cavity during the mold assembly stage in injection molding. The core is typically a metal insert that forms the final moulded part’s internal shape or hollow areas. It’s an integral part of the mold setup that interacts with the cavity to create the moulded product’s exterior and interior features. Purpose of Core Insertion The core plays a crucial role in defining the internal geometry of the plastic part. By inserting a precisely machined core into the mold cavity, manufacturers can create complex shapes, including holes, undercuts, or internal cavities, that would otherwise be impossible to produce using just the outer mold. Key Considerations in Core Insertion Precision: Proper core insertion is critical because even slight misalignments can lead to defects such as uneven walls, flashing (excess material at the joint), or poor fitment between parts. Precision in alignment ensures that the mold pr
