What are the links to be damaged during the production of copper aluminum castings?
- May 31, 2017 -


Copper and aluminum castings are special structures, so the casting process is very difficult. The most worrying thing is that the mold, once the operation is not good, it is easy to damage the casting mold, thereby increasing the cost of casting production. Now, what we need to do is to find out the factors that may affect the quality of the casting wear, and take precautions against it, and extend the service life of the mould as much as possible.

There are many damages to the casting mold, the most common form of which is crack and crack. The main cause of this problem is stress. What links do stress occur in the end?

First, mold processing and manufacturing links

If the production of mold blank in forging only guarantee the appearance size, and ignore the quality, will make the mold surface deformation and cracking. But also in the car, milling, planing and other finishing process also produces cutting stress, although this stress can be eliminated by intermediate annealing, but there will still be some impact. In addition, quenching, EDM and other processing will lead to stress.

Two, mold processing links

The molding will be after heat treatment, if improper heat treatment, will cause die cracking and premature retirement, especially with no quenching, quenching and tempering, then surface nitriding process, the problem will be more serious.

Three, casting production link

In the mold temperature, mold filling, mold opening and other technical impact, the mold will cause cracks for various reasons.

In short, anytime, anywhere may cause damage to the casting mold, so any link can not be taken lightly.
