The cavity insert forms the external shape of the molded part, while the core insert forms the internal features. They work together to create the complete mold cavity.
Replacement depends on material, production volume, and maintenance. Typically, high-wear inserts in abrasive materials may need replacement every 100,000-500,000 cycles, while well-maintained inserts can last millions of cycles.
Minor damage like scratches or wear can often be repaired through welding, re-machining, or re-coating. Severe damage usually requires replacement due to precision requirements.
