| Summary: | 碩士 === 國立虎尾科技大學 === 車輛工程系碩士班 === 105 === 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.
