This thesis deals with durability assessment for design and analysis of two plate mold insert for dog bone specimen using selected sample. The objective of this thesis is to design two plate mold insert and analyze the material flow of the selected product. The thesis describes the material flow analysis to analyzed the material flow in the part and identify the best gate locations of the components. Acrylonitrile butadiene styrene (ABS) materials were studied in this thesis as sample of material and it is commonly used in industry and lab. The structural three-dimensional solid modelling of two plate mold was developed using the computer-aided drawing software. The strategy of analysis model was developed. The material flow and gate location analysis was then performed using Moldflow Plastic Insight software. The analysis model of the components was analyzed using the two cavities with cold runner design. Finally, the orientation skin for 21 number of different gate location is analyzed. From the results, it is observed that the analysis using Moldflow material flow analysis show the different orientation skin for different gate locations. The gate locations is constrain at the middle of the part where the area that would be test for the specimen. The orientation skin at the both sides of the part is same but only change the length of runner. The increase of length of runner will increase the projected area, the clamping force, filling time and the material waste. So that, the best locations of gate is at the nearest or as short as it can for runner length to be design. But, the first priority is the orientation skin for the material flow. The orientation skin should be same at the middle of part which is parallel to the strength that would be applied on testing. The final design was done in solid modelling and details drawing using SolidWorks software. The results can also significantly reduce the cost and time to fabricate the insert. That is also can be a reference for the future works of fabrications.
