Mold Casting

metal casting has been around for a while and its a matter of tradition when we talk about types of casting.

As the evidence shows there are many various signs of this method being used for many different needs. Ever since thousands of years ago, this method has been used in various applications; from producing agricultural pieces to creating the best of armors and going to war.

In today’s article of SamenFerforge we are going to talk about the casting and its uses in the modern age.

the story of our success

Casting industry

Basically casting is done in two ways when it comes to industries. But generally the approaches are practically the same.

To play out the steps of casting you need to go through a few steps in general:

  1. Melting

In this method we heat the metal we until it deforms and losses its shape. In this step many prefer to add some scrap iron or metal to add to the elements of molten metal and add to its features.

POURING MOLTEN METAL

  1. Pouring

After melting the metal and mixing it with other materials we are going to pour the liquid into molds that we have prepared.

are you familiar with Ferforge and its many benefits?

  1. Cooling

There is nothing much you can do once we get to this stage. We need to wait for a while till the liquid cools down and take the shape of the mold.

  1. Removing

At this final step, the metal should be removed from the molds.

types of casting

There are two ways to approach metal casting in total. To use Permanent mold or Expendable molds? That is the question.

  • Permanent Molds

These molds are usually made of metals which can be used over and over again. These permanent molds are made out of two halves which locks together and can hold the molten metal until it cools down. The pressure that this mold lays on the metal is a lot and so much that the result is a metal piece with very little impurities.

This method itself has two ways off high pressure system and low pressure system of casting. The quality is always of the best.

  • Expandable Molds

This method is going to take longer than the permanent molds also it costs even more. The point is that each mold can be used only once.

After the molten metal is injected into these plasters, the liquid should cold down and shape. Then the plaster or the Expandable mold is removed by the blows of hammer. The mold breaks and what is left is the piece we wanted.

This method is both time consuming and costly, so why is it that many industries prefer this method over permanent?

Why Expandable Molds?

Why Expandable Molds?

These molds are made of cast iron which are strong and bare high pressure resistance.

Designs are better formed in cast iron molds also the result is always a piece with better detailed designs.

In SamenFerforge we also use cast iron to make expandable molds. This process has enabled us to make the most beautiful and delicate designs, also Samen has the the biggest variety when it comes to designs.

conclusion

As we mentioned, the use of cast iron in our expandable molds has enabled us into making the most beautiful designs with the highest of quality.

The use of 3D machines has enabled us to cut the tiniest of shapes and be sure if the result of metal casting process.
