Metal casting is a great creative hobby that you can use to make all sorts of cool objects, and you've likely tried your hand at it if only with some sand after an enjoyable day on the beach. But what exactly is a mold, and how do you even go about creating it? Think of a mold as to be similar like an exclusive container you can pour hot liquid metal into. You need to remove it from the mold permanently after this process so that metal freezes and become hard.
But before jumping at how to make molds, understand the types of moulds. There are two major type to familiarize yourself with: one-part molds and watertight or chamber molds. The Gravity-gietmasjiene simplest form of a mold is one part molds. These are most effective for creating simple shapes. With the latter, two-part molds have to be made which is simpler when creating rounded shapes. The Boqiao molds come in 2 halves and they sit perfectly together. When combined, they make a hole in the center for pouring the hot metal into.
Initially, an original and sculpture are placed inside a box to create the first half of a mold. Next, combine the mold material as per package instructions. Pour this Laedruk spuitgietmasjiene mixture delicately into your sculpture, until it is completely covered. Tapping lightly over the box, getting rid of any interior trapped air bubbles.
Form the Rest of the Boqiao Mold: Once half is completely dry take it out you from the box and flip them over. Put the first part back into your case. You can now make the second half of your mold the same way that you did with first.
Prepare to Cast the Metal: When the BQ smeltoond both halves of the Boqiao mold dry, apply a thin coat of release agent into each half. Squeeze out any excess release agent to ensure a clean mold surface that won't affect your casting.
Melt and Pour the Metal – Weigh out your metal you wish to cast, put it into the crucible. Heat the metal until it is in liquid form with a furnace or melting torch. When it BQ blus oond is melted use the tongs to pour in carefully into your mold.
CRACKS IN THE MOLD: If you see cracks in your mold, that probably means the material of the Aluminium giet dele mold dried too quickly. Next time, just add a little less water to your material and you wont see this issue again.
