技术 铸模制造塑料 is a comprehensive and complex process, involving aspects such as adhesive application, ejector pins, parting surface design and machining, process layout, and product appearance requirements. When handling mold design, the injection position and method need to be considered first. The use of adhesives is influenced by the number of cavities and product appearance, especially for large or complex-shaped products. The best practice is to select appropriate materials and create side or submarine gates to ensure optimal molding results. When designing runners, the length and shape are crucial; a well-designed runner not only conserves material but also promotes smoother adhesive flow. Typically, the size of the primary runner should be 25% larger than the secondary runner. For products in high-appearance-demand fields, such as cosmetics, side gates should not be used long-term to avoid surface damage. In these cases, attention should be given to the use of adhesives and submarine gates. 
Secondly, parting surface design is a critical step. When designing the parting surface, it is essential to check for undercuts to ensure the structure’s rationality, strength, and feasibility. Smooth parting surfaces and a minimized number of parting lines should be used to improve the mold’s performance and lifespan. After confirming all design elements, the core size of the mold can be determined. At this point, a 1:1 scale product view should be generated, with a mirrored copy applied based on the product’s shrinkage rate.

逐步指南：從圖紙到成型零件
“模塑製造中的「定位」是指固定零件基準面的順序，確保每個型腔都按照相同的參考進行切削。跳過步驟會導致兩個型腔產生偏離。標準順序如下：
- 設計審查 — 確認拔模角、壁厚和密封。.
- 基準設定 — 在機加工中心上鎖定 3-2-1 基準參考。.
- 粗加工與精加工 — 去除余量，然後達到公差要求。.
- 首件檢驗 — 對照圖紙進行測量。.
- 型腔平衡 — 驗證所有型腔與首件檢驗結果相符。.
經常問的問題
我實際可以保持的公差是多少？
標準模塑塑料的公差約為 ±0.1 毫米；精密模具成本較高，但可以做到更好的精度。該 ISO 20457 等級提供了在無歧義的情況下指定此項的術語。.
為什麼我的兩個型腔不一致？
通常是第二步的定位錯誤——型腔之間基準面未重新歸零。第五步驟的平衡首件檢驗可在生產前發現此問題。.
