Forging vs. Casting: Which is better?

Outsourcing Web Hosting Support: 6 Reasons Why It Makes Sense

Forging and Casting are two manufacturing methods that have ruled the industry since long now. But the manufacturing world is divided between the two processes, while a few highly favor others vote for advantages of casting. Forging Company favors forging and casting specialists suggest for casting. So here, we’ve tried to explain you about which of these processes are actually better for you.

To pick the most appropriate process for your needs, it is important to answer a few questions:

  1. What is the material that you are about to process?

  2. What Product Strength do you desire?

  3. What is the tightness of Tolerances you expect?

  4. Do you require an ultra-finished product or a raw product?

  5. What is the temperature sensitivity of the material?

  6. How much will be the net waste

Let us understand what both the processes do to the material:

Forging:

Physically strengthen a material using force while the state of the material is not altered. The material will always remain in the solid state, although the process does involve frequent heating.

Advantages of Forging:

  • Increases the strength of the material at a very granular level by constant beating.
  • Less expensive process of hardening
  • Low net waste
  • Labor costs are less in case of a Forging Company
  • No need for very high tech equipment
  • Reliable strengthening

Forging comes with a small set of disadvantages that the forged materials do not have much tolerance level. The product, shaped through forging, does not look much finished and needs rework.

Casting

Melting the material and poured into desired molds is known as casting. No physical force is required just by heating the material above the melting temperature, it is solidified into the desired shape.

Advantages of Forging

  • Increases the tolerance of the material and helps meet the exact product requirement with molding.
  • Low finishing cost as the product is highly shaped
  • One-time investment in creating exact molds.

Casting process has its own disadvantages that may not make casted products suitable for a process. The end product is porous as compared to a forged product and the entire process is costlier. The process requires a lot of monitoring.

Which Is Better?

At a comparative level, we can need to decide our preference as per the end product requirement. For example, if you need a steel product, you need to find out the tradeoffs for the final product perform better. Or, you may consult with Casting and Forging suppliers, detailing them on your exact requirements.

Some stats for you, here:

  • A Forged product has around 26% higher tensile strength
  • A Forged product has 37% higher fatigue strength.
  • A forged product offers 34% higher yield strength
  • As per trusted Forging Suppliers, a forged product is less prone to deformation as compared to cast product due to its strength at a granular level.

To Summarize

The forging process takes a lot of force to shape the material as the desired making forging to be used for large product manufacturing a difficult process so forging puts a limitation on the size of the final product. A Forging Company generally works on softer metals like aluminum, steel, nickel, and copper.

To add tolerance and finish to the product a machine touch is required. Casting offers the advantages of obtaining a precise shape and the finishing process will be shorter. Steel, brass, iron, aluminum, and tin are most suited material for casting.

While the process selection depends upon the final product that you need, you must run through the advantages of both the processes to take a right decision.
