Well, if you are considering press die casting process for your production, there you need to know some details on the same. Mainly, we are going to tell you more about the major five steps that are involved in the process of press die casting. Also, the total cycle time is very short, and it can range anywhere from 3 seconds to a minute. So, if this is a topic of your interest, you cannot miss out on any steps!
What are the major steps involved in press die casting?
- Clamping: So, in this first step, there is the involvement of preparation and clamping the two halves of the die. Each half of the die will be cleaned well from the last injection, and then lubrication will be done. This will facilitate the ejection of the next part. The time of lubrication will then increase with the part’s size along with the side cores and number of cavities. You should also know that there might be no need for lubrication after every cycle.
- Injection: The molten metal will be maintained at the right temperature in the furnace. This is then transferred to the chamber where it can be easily injected into the die. So, based on the casting machine, transferring the molten metal will be dependent on. So, either a hot chamber or cold chamber will be used. After the transfer has been complete, the molten metal will be injected at high pressure in the die. Due to this pressure, the molten metal will be held in the dies during solidification. Also, a thicker injection of the wall will require more time for injection.
- Cooling: The molten metal once injected in the die will start cooling and solidify as it enters the die’s cavity. So, once the cavity is filled, the final shape of casting will be formed. But the die cannot be opened until its past the cooling time, and the casting has solidified.
- Ejection: After the cooling time has passed, the die halves can be opened. Then an ejection mechanism will be used to push the casting out of the cavity of the die. The mechanism used for ejection needs to use strong force so that the part can be ejected. This is mainly because, during the cooling phase, the part will shrink and sticks on to the die.
- Trimming: When in the cooling phase, the materials in the die channels will solidify attached to the casting. In case, there is any extra material it must be carefully trimmed from the casting. This can be done either manually or with the help of a machine.
Well, these are the main steps used in press die casting. These, when done professionally, it will yield the best-desired results. So, you need to make sure you find the right company who will care for these needs. They need to use the right steps and equipment to give their clients high-quality results.
