Much Ado About Casting and Molding Process

We live in a world with countless products of innovation which took years and years to perfect. We get to encounter these products every single day that we tend to ignore all the effort that comes into manufacturing all the stuff we own. Do you even know what casting and molding process is? Don’t fret because we’ve got you covered.

For starters, we’ll tell you the difference between casting and moulding. Both of these processes are simple but truly amazing! We’ll even throw in the difference between mould and pattern in casting so that you can appreciate the distinction of each process.

Die Casting VS Injection Molding: Which is Better?

To tell you honestly, the answer lies in what you need. If you need a durable metal product, die casting is the obvious choice and if you need a durable plastic product, plastic injection molding would be the top of your list.

So, how can we know the difference between mould and die? In die casting, raw materials made of metal are forced into cavities made of steel molds through intense pressure. The molds are made out of two parts; the fixer and the ejector. The pressure between the two parts is maintained until the molten metal begins to solidify. After that, the casting may now be removed from the machine. There are types of die casting; squeeze casting and semi-solid molding.

The plastic molding process on the other hands works in a similar way with die casting. Instead of metal, raw materials made of plastic or polymer like duraflex material are used. The raw materials are melted and forced into molds made of steel or aluminum. The molten plastic is allowed to cool and solidify then ejected from the machines. This is the conventional method of plastic molding. The other types of injection moulding are the following; powder injection, co-injection, thin-wall, fusible core injection, injection-compression, and more.

Is there a Difference between Mould and Pattern in Casting?

Well, if you have already understood the process as explained earlier, you will know that the main difference lies in the raw materials that are used. Casting and molding process differ mainly with the fact that die casting uses metal raw materials while polymers or plastic are utilized in plastic mould. As simple as it may sound, that is the difference between casting and moulding.

What are the Applications in Casting and Molding Process?

Die casting is used in manufacturing toys, sink faucet parts, cars, gears, and more. A plastic molding company on the other hand manufactures similar products with die casting. Some known plastic molding products are dog collar buckles, kitchen utensils, car parts, appliances, packaging, and more.

What does the Future Hold for Injection Molding and Die Casting?

As we already know now, there is a little difference between casting and moulding but on what the future holds for both innovations, it’s as bright as the sunlight!

As long as the demand for quality products are present, plastic buckle manufacturers will continue to make quality products and die cast companies will continue to manufacture your favorite die cast toy cars.

There isn’t much difference between mould and pattern in casting but one thing’s for sure. Modern life will never be what it is today without the products of these two processes.
