but how to design a spure bush, I have some principles in the followin: […]
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, […]
so when we select a feeding system, what is the primary principle? I think it is to maintain the temperature and pressure as it flows out of the nozzle and fill out the cavity easily. Commonly, it prefers a “ short and thick” spure, runner, and gate. Other considerations are also given to the requirement [...]
in that case, in practice, how to make a decision on gate and runner design is very important. Because every mold has it’s making schedule. […]
Although the design of runner and gate has a great impact on the part’s molding, and quality. […]
yes! You are right, while the melt plastic passes the spure, runners and gate, it fills out at elevated temperature and reduced pressure, due to friction. The melt plastic material gradually cools off in the cavity by heat transfer.
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, […]
today we should discuss something about feeding system, because in mold design, […]
the eighth principle for deciding on the parting line is to consider the impact of draft. […]
