Basically, die casting is used to make steel molds known as dies by meting the metal to very high temperatures. Die casting is a technique that allows various manufacturers like redstonemanufacturing to manufacture different metal things like toys and steel sinks.
Workers of die casting must be sure that the die casting machine should be heated up to a required level. If the die is cold, the molten metal that is injected in the mold will strengthen too quickly without forming the correct form.
Warming will take some time according to the size of the mold. But it is very important that it is heated to the highest temperature in order to form the perfect shapes.

The first step in die casting includes spraying the mold with lubricant and then it should be closed. Lubricants help regulate the temperature inside the die and at the same time allows trouble-free removal of the cast.
In the next step the molten metal is injected into a metal die allowing the metal to take the shape of the mold without the risk of swelling or air pockets in the product.
After the mold is allowed to cool and the metal is allowed to solidify. Still high pressure is maintained in the mold so that the metal does not change its nature. Eventually die is opened and the solid cast is removed.
