First of all, many people think that if you know where to gate the part, you do not need to perform the mold flow analysis. That is a misconception and may not really help you that much in reducing costs and timing as well as may not prevent other problems. Yes you will be able to fill the parts and get the parts but will the parts be the best in very first tryout? That is a question that can be answered by performing the flow analysis.
Many times you many know the overall gate region on the part but you may not be able to locate the exact gate location to have a completely balanced fill all around the part and cavities. Such slight imbalance of 2-10% can be enough to create enough molding problems that sometime can not be seen in processing but are hidden in longer cycle time, cooling, packing issues, scrap rates, surface quality, gate or flow lines, surface finish, processing window, clamp tonnage. In today’s competitive market, this may be enough to wipe out your margins and profits. When you perform analysis from a expert source like Ideal Tech, Inc. then you not only will be able to avoid such issues but also improve your products and save cost and timing. This could be enough to add more to your pockets in the long term making your company more competitive yet producing better quality.
While analysis costs may vary from few hundreds to thousands of dollars depending on the scope of the project, this upfront costing is only one time cost that may seem to be very high initially. However such initial investment may be the cheapest way that can provide the most savings in cost and timing of product design, tooling, processing, assembly, and functional requirements. This complete upfront optimization from Ideal Tech, Inc. may the only lowest costing tool you will have to invest in only one time. On the other hand, if you perform such analysis from any source that offers cheap pricing or any body who performs a quick fill or part analysis, then you may be adding costs to your already expensive tool and not realizing any savings.
