When using standard, off-the-shelf slides, there is no question that the leadtime on a project can be reduced. The time that would have been spent squaring up blocks, machining, heat treating and grinding all of the slide components can be used to focus on the molding area—cores, cavities, slide faces, etc. […]
what is a balanced runner? The balanced runner is that all runners have identical length, shape, and sectional dimensions, from the spure to each cavity. […]
when a sprue allows the melt plastic material to flow into the cavity, that is called direct gate, in that case, the plastic part will be left with a trace by the sprue. […]
we have discussed too much about the feed system of a injection mold. Today I want to say more details about feed system assembly, […]
where is called gate in a feeding system? When melt plastic flows out of the nozzle of the injection molding machine into the mold, to a single cavity mold, […]
the third principle for deciding on the parting line is to keep the plastic part on the side of moving half of it’s mold, […]
the second principle for deciding on the parting line is to facilitate venting. You know, the end of the material flow line is a good candidate for venting. For example, […]
Gas injection, inject high-pressure inert gas such as nitrogen into the core of fusant and the gas enveloped by plastic fusant shall move forward along a direction with minimum resistance and meanwhile push the flowing front of fusant to move further forward unitl the mold cavity is fully filled. […]
fusant injection, the plastic fusant is quantitatively injected into the mold cavity. In this stage, it is very similar with traditional injection molding. […]
the most important thing is that kind of molding method does not need to open the machine and further transport of a molded part in one mold. […]
