Overmolding Solution-Vacuum Casting The overmolding process refers to injecting one material onto the surface or interior of another material product. This process is formed by the physical (buckle, surface roller pattern, thread) or chemical (cohesion, mutual dissolution) bonding of two materials together, which appear as a single component but are made of dual materials. 1. Whole Overmolding This process refers to encapsulating metal products, generally using high-hardness TPE/rubber with a hardness of 80A or above.   2. Partial Overmolding The encapsulated product can be metal or plastic. By performing hole treatment or other adhesive techniques on the wrapped parts, the physical and mechanical bonding between the two materials can be strengthened, thereby improving the firmness of the wrapped adhesive. Overmolding may apply to the following products, such as sports equipment accessories, shock absorbers, automotive air conditioning sealing rings, silicone sealing rings, plumbing valve accessories, rubber-metal parts, etc. #CNC #5-Axis #Molding #Design #mechanical #auto #medical

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

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.

What is Sheet Molded Compound (SMC)? Sheet molding compound is a type of reinforced polyester containing glass or carbon fibers. The fibers, which are typically 1” or greater in length, are suspended in a bath of resin – usually epoxy, vinyl ester, or polyester. The long fibers and sturdy resin combined produce a strong, cost-efficient material. The method by which SMC is produced ensures complete integration of fibers and resin. The resin is applied in the form of a paste to a film; next, the fibers are cut and added to the paste. The substance is then squeezed between two films; it is compacted until it reaches the desired thickness and texture and then stored for several days to “cure” until it can be sold and used.  SMC is usually sold in rolls, which are cut into smaller pieces called “charges”. Heat and pressure are applied to the charges in a process known as "compression molding", which cures the SMC and creates the final product. Compression Molding takes place in a device called a “compression molding press,” which is usually hydraulically powered. Most compression molding presses require that both the loading of SMC into the mold and the unloading of the finished product must be manually carried out by a skilled operator. The press usually consists of the upper and lower halves of the mold placed between two heated plates. Pre-heated SMC is placed into the lower half of the mold. The upper plate is then lowered, applying up to 2000 psi of pressure to the mold. Consistent application of heat and pressure causes the SMC to spread and properly fill every part of the mold. Compression molding can therefore be used to create even complex, detailed parts with great accuracy. #automotive #composites #smc #technology #knowledge Lone Wolf Consulting, LLC
