spure is located at the entrance of a mold
we have discussed too much about the feed system of a injection mold. Today I want to say more details about feed system assembly, […]
Newer CAM software advances benefit five-axis machining
Most mold and die shops rely on three-axis machines to do most of their milling work. Five-axis machines were not considered sturdy enough to mill hard materials used in Class 1 mold cavities. Moreover, five-axis programming was harder to learn and program. In general, these statements remain true. […]
How to quickly and efficiently polish an Aluminum mold
Blow molds and many prototype molds are made from aluminum. Aluminum is a very soft material and requires special polishing procedures. A fine finish can be achieved, although it may never be as fine as the finish that is possible on steel. The following is a basic polishing procedure for aluminum. In time and with [...]
Select a suitable coating for mold component
A popular practice of moldmakers and injection molders is to coat mold components as an attempt to increase the durability and achieve longer life while reducing maintenance and operational costs. This practice is certainly plausible, as it often falls short of providing the expected results and reduces the potential for maximum cost savings. [...]
innovation benefit First-rate mold solution co,ltd
In a well-established industry like moldmaking, the idea of innovation is a bit like the weather – everyone talks about it, but no one seems to be able to do anything about it. Steven , President and CEO of First-rate mold solution co, ltd., is an exception to that rule. First-rate mold solution co, ltd [...]
what is the primary principle in selecting a feeding system in mold design?
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 practice, how to make a decision on gate and runner design is very important
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. […]
the design of runner and gate has a great impact on the part’s molding and quality
Although the design of runner and gate has a great impact on the part’s molding, and quality. […]
through feeding system, the melt plastic fills into mold cavity
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 in a mold?
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, […]
