這份實習報告詳細講述了我在高性能塑膠模具設計和製造方面的實務經驗。實習的重點是獲得精密模具設計、優化生產流程以及確保工業環境中的品質控制 (QC) 標準的實踐專業知識。
在這次實習中，我掌握了使用 SolidWorks 和 AutoCAD 進行 3D 建模和 2D 繪圖、進行流動模擬和建立標準檢查協議 (SIP) 的高級技能。這些方法對於實現無缺陷模俱生產和滿足嚴格的客戶規格至關重要。此外，我還參與了整個模俱生產週期，從概念設計、材料選擇到製造、測試和品質保證。
實習的一大亮點是案例研究，涉及 iPhone 外殼模具的設計和生產，需要精密工程、迭代測試和流程優化。我與跨職能團隊合作，實施了創新的解決方案來應對流動阻力、冷卻效率和收縮控制等挑戰，確保高品質的成果。
實習不僅增強了我的技術知識，還磨練了我解決問題的能力和在團隊環境中有效工作的能力。這段經歷為我未來在模具設計和製造業的努力奠定了堅實的基礎，為我為先進的生產環境做出有意義的貢獻做好了準備。

This internship report provides a detailed account of my practical experience in the design and manufacturing of high-performance plastic molds. The internship focused on gaining hands-on expertise in precision mold design, optimizing production processes, and ensuring quality control (QC) standards in industrial settings.
Throughout this internship, I developed advanced skills in using SolidWorks and AutoCAD for 3D modeling and 2D drafting, as well as in conducting flow simulations and establishing Standard Inspection Protocols (SIP). These methodologies were critical in achieving defect-free mold production and meeting stringent client specifications. Additionally, I participated in the entire mold production cycle, from conceptual design and material selection to manufacturing, testing, and quality assurance.
A highlight of the internship was a case study involving the design and production of a mold for an iPhone case, which required precision engineering, iterative testing, and process optimization. Collaborating with cross-functional teams, I implemented innovative solutions to address challenges such as flow resistance, cooling efficiency, and shrinkage control, ensuring high-quality outcomes.
The internship not only enhanced my technical knowledge but also honed my problem-solving skills and ability to work effectively in team settings. This experience has provided me with a strong foundation for future endeavors in mold design and manufacturing industries, preparing me to contribute meaningfully to advanced production environments.
