Hi friends, this Is a very GOOOOOD example for show the deflection en this case of this núcleo. It Is the same example when we have a thin broken insert, the pressure plástic Is More strong that the insert and in the future we have a broken insert and we aré thinking about the root cause for this Is very importan have a designer that know how Is the pressure in machine and check the thin or long part with this problem for this example Is very simple improve this conditions, only need make the núcleo More long for have a looking fit vs the cavity and reiforce for the plástic pressure. For these cases there is software that tells you where the pressure is being increased. If you don't have it, it is easy to detect, you just have to make cuts in the plastic piece and the deflection will be very noticeable. I hope my comment can help you in similar cases, thank you.

Core Deflection during Cavity Filling www.kruseanalysis.com / www.krusetraining.com / www.molding-expert.com Core deflection during injection molding occurs when the molten plastic pushes against the core—an internal feature or protrusion used to shape hollow or complex areas of the molded part—as it fills the mold cavity. This can cause the core to bend, shift, or break due to the high pressure exerted by the flow of material. Core defection leads to dimensional inaccuracies, part warping, or defects such as inconsistent wall thickness or misaligned features in the final product. It's essential to ensure proper core strength, mold design, and material flow control during the injection process to prevent this. #injectionmolding, #plasticsindustry, #moldmaking, #molding, #moldingdefects #plasticinjectionmolding, #plastics, #plasticsengineering, #molddesign, #partdesign, #moldex3d, #Spritzguss, #plastics, #plasticinjectionmolding, #plasticsengineering, #partdesign #arburg,#kunststofftechnik #kunststoffe ,#seminar, #kunststoffindustrie, #polymers,#moldmaking, #moulding,#mouldmaking,#mouldmaker

Part Ejection Challenges due to High Internal Cavity Pressures www.kruseanalysis.com www.krusetraining.com www.molding-expert.com In plastic injection molding, high cavity pressure can result in elevated internal stresses within the molded part. These stresses arise from the excessive force required to fill and pack the cavity to compact the material. Consequently, parts may exhibit warping, cracking, or high molded-in residual stress-related failures over time. Additionally, high cavity pressure can cause ejection issues, as the part may adhere more strongly to the mold surface or experience distortion during ejection, making it challenging to release cleanly. Understanding the reasons for high internal pressure is essential. Proper cavity pressure control is crucial to ensure dimensional accuracy, structural integrity, and ease of ejection in molded components. #injectionmolding, #plasticsindustry, #moldmaking, #molding, #moldingdefects #plasticinjectionmolding, #plastics, #plasticsengineering, #molddesign, #partdesign, #moldex3d, #Spritzguss, #plastics, #plasticinjectionmolding, #plasticsengineering, #partdesign #arburg,#kunststofftechnik #kunststoffe ,#seminar, #kunststoffindustrie, #polymers,#moldmaking, #moulding,#mouldmaking,#mouldmaker

Wall Thickness Variations in Molded Parts and the Impact on Freeze-Off www.kruseanalysis.com / www.krusetraining.com / www.molding-expert.com In manufacturing, particularly in injection molding and other molding processes, controlling wall thickness variations is crucial for producing high-quality parts. These variations can significantly impact the finished product's structural integrity and aesthetic quality, potentially leading to product failure or customer dissatisfaction. Additionally, inconsistencies in wall thickness can lead to a phenomenon known as "freeze-off," where parts of the mold solidify prematurely, disrupting the flow of material and affecting the outcome. #injectionmolding, #plasticsindustry, #moldmaking, #molding, #moldingdefects #plasticinjectionmolding, #plastics, #plasticsengineering, #molddesign, #partdesign, #moldex3d, #Spritzguss, #plastics, #plasticinjectionmolding, #plasticsengineering, #partdesign #arburg,#kunststofftechnik #kunststoffe ,#seminar, #kunststoffindustrie, #polymers,#moldmaking, #moulding,#mouldmaking,#mouldmaker

This shows the effect of design features on mold processing. Wall thickness variations as well as rib thicknesses play a vital role in melt filling and packing. A good explanation on the same. Worth sharing by Kruse Training.
