Why look at a theoretical number like the perfect
cooling time? One reason to compare "current" cooling to the perfect cooling prediction is to determine if it would be worthwhile to improve the cooling.
Plus, if you have a large gate and run a hot mold, you should be able to reduce your melt temperature, which will not only decrease
cooling time but also improve part quality.
Cooling times were established following determination of gate seal.
It is an important factor to improve workability and to shorten
cooling time at the work site.
These wide swings in temperature are the result of changing sand-to-metal ratios, casting
cooling times and poured vs.
In these examples, the tail temperature is illustrated as a function of
cooling time for two melt temperatures.
Not quite that much time, though, because within this
cooling time, your machine has to be doing some other things:
This process of pre-cleaning castings with their runner systems still attached helps decrease casting
cooling time by removing the insulating surface sand.
It simulates the electromagnetic field, displaying mold temperature, heating time,
cooling time, where to place inductors and cooling channels, and what tool alloy is best suited to the part design and molding material.
Each mold has a cycle time between 32 and 34 sec, but overall cycle time is reduced since the
cooling time of one mold face overlaps the injection phase in the other face.
When used with a pushout system, extra
cooling time should be given the furnace before attempting to "push" linings with a full patch.
The simulation was carried out for a filling time of 30 sec, a
cooling time and mold open time of 1 min after ejection, and a total cycle time of 7 min.
