Based on annual or project order volume and delivery schedule, calculate the required daily output. Higher total demand generally favors multi-cavity designs to reduce the mold cost per part.<\/p>\n\n\n\n
Accurately measure the complete molding cycle (including injection, packing, cooling, and ejection). Shorter cycle times increase single-cavity output, allowing a lower cavity count and avoiding over-investment.<\/p>\n\n\n\n
Match cavity number with machine clamping force, shot capacity, and workshop scheduling to maximize overall equipment effectiveness (OEE) and ensure the mold aligns with available resources.<\/p>\n\n\n\n
Abrasive materials such as glass-fiber or mineral-filled resins significantly accelerate cavity wear. In these cases, prioritize high-quality mold steels (e.g., S136, H13) and moderately reduce the number of cavities to extend mold life and lower long-term maintenance costs.<\/p>\n\n\n\n
