As far as aluminum sand casting is concerned, know that it can offer a lot of advantages. These advantages fall in a lot of categories including logistics, finance and so on. Let’s take a look at some prominent advantages.
1. Flexible Quantities
Flexible production quantity is the first main advantage. For instance, some castings can deliver up to 100,000 pieces per year. This is possible because of innovative mold designs that can balance unit and tooling costs.
2. High Strength
This process gives high strength. Molten aluminum is put into a strong metal mold that reduces the mold temperature. As a result, the metal solidifies into a fine-grain texture, which is free of trapped gas and porosity. Therefore, your castings enjoy much better quality metallurgical properties, higher strength and pressure tightness.
3. Less Machining
Machining costs a lot of money. The goal of manufacturers is to reduce the use and cost of secondary machining. They do so by offering close dimensional control, total repeatability and a smooth finish. Also, this process allows flat casting of the surfaces. At times, they are free from any taper or draft.
4. Low Cost
The biggest benefit of aluminum sand casting is low cost. Since machining is reduced during this process, customers can enjoy much lower unit costs. Engineers use their experience and knowledge in order to produce new mold designs. And this helps reduce the tooling costs considerably.
5. Molded Inserts
Aluminum sand casting allows you to cast molded inserts. Typically, the casting is cast with the help of a stainless steel insert in order to offer a wear-resistant, hard surface and keep the other part lightweight.
Also, the casting is designed to offer wear-resistant and durable threads. At times, cast-in threaded ones offer lower costs than CNC taping or drilling. Regardless of this, molded inserts offer cost-saving techniques.
6. Smooth Surface Finish
Fine surface is another great advantage you can enjoy if you follow this technique. The finish is smooth enough for gaskets and o-ring seals in a number of applications. Also, they are smooth enough. Aside from this, the castings feature a clean appearance that can help reduce the need for many expensive operations, such as mass finishing and polishing. Apart from this, it’s easy to tumble, paint, plate, coat, anodize and polish the castings.
7. Close Tolerance
Usually, metal molds are used to make castings. Therefore, the dimensional variation and close tolerance of the pieces is negligible. So, you can enjoy higher precision and accuracy. Also, you can cast a lot of parts without machining. As a result, you can save a lot of money.
8. High Quality
For guaranteed high-quality castings, upfront engineering and process control are quite important. The combo of these two can help exceed industry standards by reducing the failure rate and internal scrap. This is done by keeping an eye on all the processes and investing a lot of effort into designs and development processes.
