The Benefits of Sand Mouldings in Aluminium Casting

Published - 19th Nov 2022

Sand casting is a very popular casting process, primarily because of the many benefits sand mouldings offer the casting process.

Key properties of a sand moulding

There are specific properties of sand moulds that have an important impact when we are creating quality castings. These include:

  • Strength: Sand mouldings hold their shape under high stress
  • Permeability: Sand allows gas and steam to escape during the casting process
  • Flowability: Sand can fill small cavities and create a more precise mould
  • Collapsibility: Sand allows the metal casting to shrink without the risk of cracking
  • Refractory Strength: Sand can withstand extreme temperatures
  • Controllable moisture content: Too little moisture in a mould may cause it to break apart. Too much moisture can cause steam bubbles
  • Reusability: Sand can be reused for making new moulds

The benefits of using sand mouldings

The properties of a sand mould provide it with numerous and very specific benefits:

  • Cost effective: Low tooling costs makes it one of the cheapest methods, making it ideally suited for lower volume needs.
  • Offers wide material choice: As these moulds can withstand high temperatures they can be used with many different materials, including those with high melting temperatures.
  • Quick to set up: This makes sand moulds great for prototyping and small production runs.
  • Flexibility: Sand can be used to create moulds of many different sizes and with basic or complex shapes, making it useful for a large variety of designs.
  • Quality surface texture: Using the right finish with these moulds can give an excellent surface texture.
  • Minimal wear: Patterns used to create the mould can be reused many times with minimal wear during production.
  • Environmentally friendly: Sand can be recycled to be reused which helps to ensure minimum waste and cost.
