Die castings

Metal casting is an important technique in many industries. The most common metal casting process today is sand casting, but other methods like die casting, or investment casting are also popular and widely used.

The casting process has been used for thousands of years. There are many different types and all result in a great finished product.

Advantages Of Casting

Casting is a process that allows you to make complex shapes without the cost of other methods. It is also environmentally friendly.

Sand Iron Castings

Sand casting is the process of making molds by using sand. This process uses molten metal and has to be cooled so that it can cool down before the mold is broken apart.

One of the biggest differences between Sand Casting and Die Casting is that anything can be used to make sand molds. This means the initial set-up time is lower and the lead time on new products is shorter. Another advantage of sand casting is that parts can be very large.

A cast is made by shaping sand around a metal mold. The part cools and the sand falls away. Sometimes, if needed, a separate piece of the mold is created to make the part more complicated (with an inner hole).

Investment Casting

Investment casting is a manufacturing process that replicates designs in wax. The wax material is dissolved from the ceramic replica before pouring molten metal into the mold. Thin, intricate patterns can be possible with investment casting.

Die Casting

Die casting is a type of process that is referred to as a “permanent mold” process because the mold is reused while molding from part to part. As the name suggests, this process uses a hard die into which liquid metal is injected under pressure to form the part being made. Once the metal is injected into the die, it is cooled to harden, and then ejects the part from the die. While the initial cost of manufacturing these dies is high, they are very cost-effective in long term, because it’s reusable and very fast.

Die Casting is a high-end production process that allows for very precise and accurate pieces to be created at a low cost. A die is used as the mold and molten metal is injected under pressure into the cavity, then cooled and hardened to create a perfect casting with high velocity.

What is casting and where is it used?

What is casting and where is it used?

Casting is a manufacturing process that was used in the Copper Age to produce castings from liquid metal. This type of manufacturing is still popular today because it is highly reproducible and efficient. Castings can be found everywhere from manhole covers to aircraft engines.

The casting process comparison

Die Casting and Sand Casting

Sand casted parts are made in a different process and have thicker walls. They require more machining, less precision, and higher tooling costs but they’re quicker to produce and can be made with lower part cost and smaller minimum quantity requirements.

Die Casting and Forging

Forgings are denser and stronger than die-cast parts. They can be produced in calcium, iron, and other metals, and larger sizes than diecasting. Die cast parts have more intricate shapes and forges can’t produce them.

Die Casting versus Stampings

Die castings are more complicated and can be made in more shapes and sizes. However, it can still replace several parts with one die casting. Diecast parts require less assembly operations, have less waste, and are able to be made in more complex shapes.

Cold Casting versus Plastic Injection

The cold cast polyresin product is a cheaper option than the injectionmold, so it enables shorter production runs. With the colder molding process, the product can be more detailed and contain more undercuts. The other advantage of polyresin over injection plastic is that with cold cast molds we are able to create things faster and with less variation. Injection molded parts on the other hand are stronger, more stable, heat resistant and have less variation than cold cast parts.
