Pressure Die Casting is the fancy name we give to die casting metal these days. The process involves injecting molten metal into a 3d mold to get a finished part or product done in a matter of moments. The usual suspects preferred for this manufacturing method are aluminum, lead, copper, steel, zinc, and magnesium. This manufacturing process is as sold as the time humanity has been using metal artifacts to get tools done, but it has evolved a great deal since the time of the swordsmiths.

These days we need to follow four basic rules to get pressure die casting done right, so buckle up and take notes. You need to know this to get a well-made product done with this manufacturing method:

Do the Prep Work for your Mold

Getting your mold ready is easier said than done. The workshop you are working with better takes their time lubricating the mold's interiors walls down to the last crevice. This will help regulate the temperature and create a protective layer between the metal and the mold itself, making the process easier to remove the finished product once you are done casting.

Get the Injection Process Calibrated Right

Once the production cycle begins, there is no stopping it. Before you get started, you have to make sure the clamping process goes without issues. Your mold will have to open and close quite a few times, depending on the production run you have set for it. If the clamping is not calibrated to perfection, you risk having a defective product in hand. Also, we should examine the pressure it closes with attention because, if for any given reason the mold doesn't close the way it's supposed to, you will have leakages and waste a lot of money.

Check the Cavity Ejection

If your mold has ejection pins, you need to check they are working the way they are supposed to. These ejection pins are the ones that keep the production cycle running smoothly. Once your part is done, the machine goes for another one with the pins ejecting each finished part every single time. After that, go for the cooling time, especially if the pin has to eject the product after cooling. The last thing you want is to create a mess by having the ejection pins expelling something that hasn't had the time to cool off properly.

Make Sure the Shakeout Runs like Silk

No pressure die casting is perfect; even when you are incredibly careful, you will have to get rid of the scraps of metal that fill the mold's cavities. The mold needs a shakeout to get rid of any excess and to get ready to create a newly casted part. This process takes a fraction of a minute, and it's mostly automated, but as it happens with all else we mentioned on the list, it needs to be fine-tuned by a human technician before getting started; otherwise, you get finished parts full of impurities or with charred surfaces.
