Do you often have problems with metallic particles in the hot runner or in the tool? Is the subsequent disassembly/cleaning of the tool too complicated and time-consuming? This is particularly an issue with a central plastic supply via pipes. There is a simple solution: flow filter V. Advantages: ✔ Trouble-free injection molding without failure ✔ Only a minimal increase in spray pressure ✔ Low energy consumption

"An Improper Gate Location Can Cause Core Deflection." www.kruseanalysis.com www.krusetraining.com www.molding-expert.com An improper gate location in casting or injection molding can cause core deflection, which occurs when the flow of molten material exerts uneven pressure on the mold's core. This uneven pressure can bend or shift the core, leading to defects in the final product, such as uneven wall thickness, misalignment, and compromised structural integrity. Proper gate placement ensures balanced flow and minimizes the risk of core deflection, thereby improving the quality and consistency of the manufactured parts. #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

The strategy of ejecting a multi-part mold insert together with the article allows external cooling outside the injection molding machine. In this way, the thermal problems of polymer inserts in rapid tooling can be solved. This is accompanied by a simplified design, as a complex temperature control ejector system is no longer required. This approach and all its advantages can also be transferred to steel molds. 👉 Read the full article (PI+): https://lnkd.in/duVpRJaP Text: Dr.-Ing. Stephan Kartelmeyer, Finn Welling, B.

🌈 Analysis of the causes of cracking of injection molded products 🚀🚀 🔥🔥 1. Processing: ✅ Excessive processing pressure, too fast speed, too much filling, too long injection and holding time will cause excessive internal stress and cracking.⚡ ⚡ ✅ Adjust the mold opening speed and pressure to prevent rapid strong pulling of the parts from causing demolding cracking. ✅ Properly increase the mold temperature to make the parts easy to demold, and appropriately lower the material temperature to prevent decomposition. ✅ Prevent cracking due to weld marks and plastic degradation causing low mechanical strength. 🔥🔥 2. Mold: ✅ The ejection should be balanced, such as the number of ejector pins and cross-sectional area should be sufficient, the demolding slope should be sufficient, and the cavity surface should be smooth enough to prevent cracking caused by residual ejection stress concentration due to external force. ✅ The structure of the part should not be too thin, and the transition part should use arc transition as much as possible to avoid stress concentration caused by sharp corners and chamfers. ✅ Use as few metal inserts as possible to prevent the internal stress from increasing due to the different shrinkage rates between the inserts and the parts.⚡ ⚡ ✅ For deep-bottomed parts, appropriate demoulding air inlet channels should be set to prevent the formation of vacuum negative pressure. 🔥🔥 3. Materials: ✅ The recycled material content is too high, resulting in low strength of the parts. ✅ Excessive humidity causes some plastics to react chemically with water vapor, reducing strength and causing ejection cracking.⚡ #injection #mold #injectionmolding #molding #ejection #material #process #mould #tooling #plastic #plastic #demoulding #demoulding #cavity #surface

This is a key factor in a capable process development. Understanding the correct transfer position will help to create the optimum pack sequence and gate seal. This provides for a consistent product to be produced.

A Smooth Transition to the Packing Phase www.kruseanalysis.com / www.krusetraining.com / www.molding-expert.com When a molding machine switches from the filling phase to the first stage of packing pressure, the internal cavity pressure typically increases. During the filling phase, molten material is injected into the mold cavity at a high velocity, gradually building up pressure as the cavity fills. However, once the filling phase ends and the machine transitions to the first packing stage, additional material is injected at a lower speed to compensate for shrinkage and ensure the cavity is fully packed. This results in a rise in cavity pressure as the material densifies and compresses the molten material inside the cavity. The transition from a speed-controlled phase to a pressure-controlled phase should be accomplished without pressure spikes or dips. The goal is a smooth transition. The pressure increase is crucial in ensuring that the final part has the correct dimensions and surface quality. #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
