摘要
本研究主要探討堆高機飾板的翹曲問題，若變形量太大可能會影響不易組裝；若太小可能會造成密合度出現問題。 在塑膠成形的製程中除了要有好的成品設計、模具設計與材料性質外，還要有適當的製程參數，以往的製程參數主要依賴經驗的累積與誤試法來找出較佳參數，但這種方式通常使用較多的時間與金錢；現今透過電腦輔助工程(Computer Aided Engineering，CAE)可以在製造模具前改善缺陷，減少試模、修模的時間並降低其成本，來提高產品的利潤。 本研究分析進澆設計使用單點進澆與兩點進澆的優劣；使用不同的水路方法，傳統水路與異形水路；材料方面加入含有15%及30%的玻璃纖維；利用模流分析軟體(Moldex3D)來模擬實際射出情形，比較不同進澆方式在不同水路設計及含有不同成分的玻璃纖維時的分析結果，探討成型後的收縮問題、冷卻不均問題與變形量問題，解決產品翹曲狀況。

This study mainly discusses the stacker panel warpage, if the amount of deformation too large may affect the assembly, too small may cause problems with the degree of compacting. In the plastic molding process, not only have a good product design, mold design and material properties, but also have the appropriate process parameters, the conventional process parameters depends on accumulated experience using trial and error method to find a better parameters, but this often wastes more time and money; now you can improve defect through Computer Aided Engineering(CAE) before manufacture of molds, to reduce time and cost by test mode, and repair mode to improve products profit. This study investigated the advantages and disadvantages of using one-point pouring and two-point pouring, compared different methods of water, traditional waterways and profiled water guides was also compared. Material of 15% and 30% glass fiber was considered. Mold flow analysis software (Moldex3D) was used to simulate the actual situation of injection. Analysis of the results in different pouring methods and different waterway design and containing different ingredients of glass fiber was valued. The shrinkage was studied after molding, the uneven cooling and deformation problems were also discussed for solving product warp condition.
