20+ Differences Between Cast And Mold

Cast and Mold are two terms that sound like synonyms and have many similarities between them. Hence, many times, they are used interchangeably. Casting and Molding are two processes that are used to create 3D models of various objects.

 To make a 3D copy of anything, firstly, a mold is prepared. Now, something liquid is poured into that mold to make a cast. A Cast is a finished product that is the 3D copy of the object. Mold is a 3D copy that is used to make other copies, known as Cast. 

The major difference between a Cast and Mold is that a cast can not be used to make other casts, a cast is a final product, but a number of casts can be made from a single mold.

Major Differences Between Cast And Mold

What exactly is a Mold?

A mold is a hollow 3D impression of an object whose copies we want to create. First, the original object is placed in a box, and then a liquid material is poured over it until it becomes solid. And then crafted for the desired shape. That is how Molds are made.

The process of making a Mold is known as Molding. Molding is the first step of making a copy of an object. Molds are then used to make Casts. Multiple Casts can be made from a single Mold.

  2. The process of making a mold is known as Molding. 
  3. Multiple Casts can be made from one Mold. 

What exactly is a Cast?

A Cast is a 3D copy of an object made from a Mold. Liquid material is poured into the Mold, allowing it to settle down and become solid. When it becomes solid, it is taken out of the Mold, and that is how a Cast is prepared. 

The process of making a Cast is known as Casting. Casting is the final step of making a copy of an object. Casts are generally not used to make copies from them, but in rare cases, they can be used to do so.

Contrast Between Casting And Molding

Origin Of The Word

  • Cast – The word Cast originated from the Middle English word “casten,” meaning “to throw, cast, overturn.”
  • Mold – The word Mold originated from the Latin word “modulus.”

Purpose

  • Cast – A Cast’s purpose is to be a 3D copy of the original object. 
  • Mold – A Mold’s purpose is to make a number of casts. 

Process

  • Cast – The process of making a Cast is known as Casting. 
  • Mold – The process of making a Mold is known as Molding. 

Product Stage

  • Cast – A Cast is a final product. 
  • Mold – A Mod is used to create other Casts. 

Process Stage

  • Cast – Casting is the final stage of making a copy of an object. 
  • Mold – Molding is the first stage of making a copy of an object. 

Products Used

  • Cast – The products generally used in Casting are plastic, silicone, latex rubber, epoxy resin, etc. 
  • Mold – The products used in Molding are wax, clay, silicon, hot glue, etc.

Conclusion  

The words “Cast” and “Mold” are widely used as synonyms because both are used to make a copy of the original product. Although, they both have different differences which should be kept in mind.

To serve the purpose of creating multiple 3D copies of anything, the first thing that is made is a Mold. Making a Mold is the first step of this process. It is on the basis of Mold, and multiple casts are made. 


FAQs (Frequently Asked Questions)

Q1. What is the major difference between a Cast and a Mold?

One of the differences between a Cast and Mold is that the former is the last stage of this process while the latter is the first stage of this process.

A Cast is the end product. A single Mold can be used to make multiple Casts, but Casts are generally not used to make other Casts. 

Q2. What are some of the materials that are used in making Casts and Molds?

The materials which are commonly used in making Casts and Molds are plastic, wax, silicone, clay, latex rubber, hot glue, etc. 

Q3. What is meant by Molding?

The process of making a Mold is known as Molding. A mold is generally made to make Casts. 

Q4. What is meant by Casting?

The process of making a cast is known as Casting. Casts are made from Molds.
