Aluminum Die Casting Design Guide: Things to Consider before Start

When designing an aluminum die-cast component, it is imperative to consider various factors such as its application, appearance, functionality, precision, and ultimately, the cost. Initially, it is crucial to establish clear objectives for the part and make a balance between the requirements and the allocated budget. Below, we have outlined the key considerations that should guide your design.

1. Using Function

When designing a product, it is essential to think about its possible applications. Aluminum die-cast parts have gained popularity due to their ability to fulfill both structural and aesthetic functions, making them a preferred choice over other materials. Thanks to the advancements in modern computing power, the accuracy achieved through die casting has significantly improved.

You should communicate the specific application of your parts to the die caster. This information is crucial as it enables them to assist you in selecting the optimal material and determining appropriate tolerances for the design parameters, tailored to your requirements. Additionally, it is essential to consider key properties such as corrosion resistance, strength-to-weight ratio, and conductivity.

However, it’s common for customers to overpay for quality and strength that exceed their actual needs. Therefore, having a clear understanding of the functional requirements of your parts provides deeper insight into the die casting process. This understanding can help you make informed decisions, ensuring that you only pay for the necessary quality and strength, optimizing costs and meeting your specific needs.

2. Appearance Requirement

The appearance of internal aluminum die-cast parts may not be as crucial, but it becomes significant when dealing with exterior casting parts such as housings or casings.

End users always prefer aesthetically appealing products, so the looks of a part is equally important to its performance. Consequently, external die-cast components must possess an attractive appearance.

Therefore, when designing your parts, it’s crucial to consider aesthetic aspects. It’s advisable to plan ahead the desired surface finishing you want to achieve. A superior finishing not only enhances the aesthetics but also provides additional protection against harsh weather conditions. 

3. Assembly Method

The complexity of aluminum die-casting parts can range from relatively simple to highly intricate, depending on the design specifications. Historically, conventional die casting equipment posed limitations on the types of parts that could be cast, making it challenging to produce parts with intricate details.

However, modern advancements have overcome these limitations. Complex parts can now be divided into suitable segments and joined together after casting using various assembly techniques. Some common die casting assembly methods include fastening, threading, welding, injected metal assembly, and cored holes.

It’s crucial to select a specific assembly technique for your die-cast parts before initiating the design process. The chosen assembly method will significantly impact the design decisions you make. It’s essential to evaluate each technique and choose the most suitable option that fulfills your specific requirements and objectives.

4. Cost Budget

It is imperative to conduct a thorough cost budget analysis for your project, as budget considerations have a direct bearing on every aspect of your manufacturing business. Consequently, your design must align with your allocated budget.

An experienced designer can significantly minimize die casting expenses while maintaining the integrity and quality of your parts. To avoid unnecessary costs resulting from overdesign, it’s crucial to adhere to specific design parameters.

For instance, incorporating pockets into your design enables you to create lighter parts without compromising performance, thus reducing material costs. Additionally, reducing or eliminating undercuts and sharp corners can significantly lower tooling and casting costs while simplifying the manufacturing process.
