How much do you know about precision casting?

Precision casting may be very strange for some friend, but for our precision casting factory is familiar with, because we are manufacturer of main do is it, if you need this knowledge can contact our factory, below is our manufacturer finishing for the user to determine the precision casting with pressure and mould and method of filling time, hoping to bring some help to users.

1. Pressure holding time.

The length of holding time depends on the material and wall thickness of precision casting.For castings with high melting point, large crystallization temperature range and thick wall, the holding time is longer.For the casting with small crystallization temperature range and thin wall, the holding time can be shorter.If the holding time is insufficient, it is easy to cause shrinkage.But the pressure holding time is too long, not very large effect, but easy to cause the vertical die-casting machine to cut the residual material difficult.

Second, mold opening time.

After holding pressure, mould should be opened to take out precision casting products.The time from the end of the injection to the die casting die opening is called die opening time.Enough time to make the precision casting in the mold will have a certain strength, mold opening and ejecting will not produce deformation or crack.If the mold opening time is too short, the mold will be released when the casting strength is still low, and the casting is easy to deformation.

Iii. Filling time

In die casting, the time required for liquid metal from entering the die casting mold cavity to filling the mold cavity is called filling time.The length of filling time depends on the size and complexity of the precision casting.
