Key Design Tips for Durable Deep-Drawn Metal Components

To achieve optimal durability in deep-drawn metal components, it is imperative to adhere to core design principles that enhance strength, reliability, and service life. Below are the critical guidelines to follow.

1. Choose Appropriate Materials for Durability and Formability

Material selection serves as the cornerstone of deep-drawn part design, as it exerts a direct influence on the component's strength, formability, and resistance to environmental factors. Common metals utilized in deep drawing include stainless steel, aluminum, brass, and low-carbon steel—each offering distinct advantages tailored to specific application scenarios.

Stainless Steel

Famous for its robust mechanical strength and corrosion resistance, stainless steel stands out as an ideal option for parts operating in harsh environments or those requiring long-term durability.

Aluminum

Aluminum features light weight and inherent corrosion resistance, making it particularly suitable for components where weight reduction is a key requirement.

Brass

Brass delivers excellent formability and corrosion resistance, and is widely applied in scenarios that demand high wear resistance performance.

Low-Carbon Steel

Combining favorable formability and sufficient strength, low-carbon steel emerges as a cost-effective solution for manufacturing durable deep-drawn parts.

2. Optimize Wall Thickness to Balance Strength and Formability

Wall thickness is a vital factor affecting the strength and durability of deep-drawn parts. The core challenge lies in finding the right balance: ensuring sufficient thickness to guarantee strength while maintaining adequate formability to avoid cracking or tearing during processing.

Uniform Wall Thickness

It is advisable to maintain consistent wall thickness throughout the entire component to eliminate potential weak points. Excessive thinning of the wall may lead to structural failure under stress, while overly thick walls can cause wrinkling issues during the drawing process.

Thinning Allowance

Thinning of the material is an inevitable phenomenon during the deep drawing process. Therefore, the initial wall thickness of the part should be designed appropriately to accommodate this thinning effect without compromising the structural strength of the final product.

Material Considerations

Different materials possess varying levels of tolerance to thinning. Highly ductile metals, such as aluminum, can withstand more significant thinning, whereas brittle metals usually require a thicker initial wall to prevent damage.

AUNOV Advantage

AUNOV's engineering team conducts in-depth analysis of each design to determine the optimal wall thickness. Leveraging their rich experience with various metal materials, they develop components that achieve an optimal balance between formability and strength, ultimately enhancing overall durability.
