多腔模具可在一次成型週期內生產多個零件，但僅憑模穴數並不能決定生產速度、良品產出或單件成本。決策取決於需求、機台產能、流道與模穴平衡、零件幾何、模具投資、製程穩定性，以及每個模穴可用的佐證。
區分多腔模具與家族模具
多腔模具通常成形同一零件的多個實例，家族模具則在一套模具中成形不同零件。後者會帶來零件數量、充填平衡、品質驗收，以及是否所有零件都需在同一生產組合中的額外問題。比較報價前請先說明考慮的是哪一種配置。
核查機台與量產限制
Ask the supplier to confirm the intended machine’s available shot capacity, clamp capacity, plasticizing capability, platen and tie-bar space, and production schedule assumptions. Autodesk’s guidance on selecting cavity count lists machine size, shot volume, production time, required quantity, molding geometry, and mold cost among the factors to consider.
Review cavity and feed-system balance
Ask how the runner, gates, cooling, venting, and ejection are designed to support consistent filling and acceptable parts from each cavity. Autodesk describes runner balancing as dependent on molding conditions, gate locations, runner layout, and the desired filling behavior. Simulation can help compare a proposed design, but sample inspection by cavity is still needed to confirm the tool under the intended conditions.
Compare total program cost
Compare tooling, sampling, maintenance, change parts, machine time, material use, inspection, scrap risk, and the expected production mix. A higher cavity count can increase parts per cycle, but a more complex tool may also require greater investment and maintenance. Ask suppliers to state assumptions about annual volume, operating time, yield, cycle time, and downtime so the comparison uses the same basis.
Define cavity-level validation
- 識別每個模穴，並定義樣品的標示與檢驗方式。
- 設定尺寸、外觀、組裝與功能的驗收標準。
- 記錄材料牌號、機台、製程版本與抽樣條件。
- 議定特定模穴缺陷、維修或製程變更的圍堵與重新驗證方式。
