Sand casting is a type of casting technique that uses sand to make the casting mold. The sand is usually combined with a binding agent and some additives to increase its strength and firmness. The additives also add good qualities to the product. Sand casting products are some of the most durable parts manufactured. They often feature an intricate design. The technique can also be used to make simple parts. The popularity of sand casting can be attributed to its numerous benefits. In this write-up, we discuss sand casting benefits.
The benefits of sand casting
Below are the primary advantages of this casting production technique;
One of the primary benefits of sand casting is that it is highly cost-effective. The production costs for sand casting are low. This is primarily because the tooling costs are lower. For this reason, it is an ideal production technique in the instance where lower production volumes are required. However, the cost of the process usually depends on the material used to manufacture the part. The most common materials applied are plastic, wood, and metal. Plastic and wood are generally cheaper than metal.
2. Versatility and variety
You can use the technique to manufacture a variety of products. Sand casting also allows the use of a wide range of metals. This includes metals with high melting points. In most cases, such metals would cause the mold to melt if used in other casting methods. Besides the variety, sand casting is also one of the most versatile production techniques on the market. This is because it can create varying product sizes and weights, including parts weighing more than two hundred tons. However, most sand casting requires machining of the surfaces.
3. No quantity limitations
With sand casting, you can produce large quantities of parts. Since this technique’s tooling cost is simple, making single-piece runs is also possible and straightforward. The method also allows you to produce large product volumes. However, despite the lack of quantity limitations, you must ensure that the design elements and tolerance are high-quality. They also have to be prepared correctly for the casting process to run smoothly.
4. Accuracy and speed
The process also offers a high level of accuracy. This is the reason why it is applied in manufacturing large and complex products. Regardless of the product size, the technique maintains its accuracy. In most cases, it also allows for a good surface finish. Additionally, the production method is also fast.
Sand casting is also one of the most eco-friendly methods of production on the market. Recycled scrap metals can be used to make new products. Additionally, the sand used can be reused in the casting process. The process also does not use harsh chemicals. The chemicals used as binding agents and additives are not discarded into the environment.
The sand casting production method is the oldest form of casting in existence. The production method has been around for more than 5000 years. Regardless of its age, it remains one of the most popular production methods. Its timelessness can be attributed to all the other benefits listed in this post, plus the fact that it is faster than other techniques.
