Die casting, is the most widely used in a variety of casting processes, which is characterized by the use of mold cavity to melt the metal to exert high pressure. Compared with other metal casting technology, die-casting surface is more smooth, more consistent size, and lower cost. In the die-casting process, there are some common problems, will affect the normal use of the machine and the accuracy of casting, then what are the problems, what kind of solution? Here we look at the following:
Casting casting production process of the most common nine problems and their solutions:
The first question: hammer stuck
Solution: 1 in the production, often measuring the temperature, to avoid the hammer, the Secretary of the cylinder temperature is too high; 2 use high-quality, non-impurity alloy material, to avoid impurities in the hammer.
The second question: the head of the head in the gooseneck
Solution: and other equipment at room temperature, try to turn the hammer, such as can not turn, then change the Secretary, the hammer out. If you want to quickly solve the stuck problem, the best is the replacement pot.
The third question: playing when playing dozens of mold material can not play, to wait a few minutes to continue to feed
Solution: to see whether there is a bright spot on the top of the head, such as all the gray section, then the block Tsui, the nozzle temperature can be appropriately increased, the time from the nozzle down 0.1 to 0.2 seconds, fixed cooling water slightly Off the point.
The fourth question: die-casting thin-walled products easy to crack
Solution: the emergence of this problem may be a problem with the material or mold is not open or improper selection of process parameters, try to control the proportion of waste should not exceed 30%, stay time should not be too long, about 3s per mm wall thickness, When not long, generally 0.5-2s.
The fifth question: the material is too hard, the tool is easy to wear
Solution: With the original material ratio, no renewable materials, the use of specifically for the carbide production of gemstone blades.
