Stamped Automotive Suspension Components Manufacturing

Metal stamping is a commonly used process for automotive suspension components manufacturing in 2025. Let’s have a look at the types of automotive components that are being manufactured by stamping today and the technology required to ensure these auto parts meet Tier 1 automotive manufacturing standards.

Demand for certified, high quality parts for auto tier 1 supply chains

Automotive parts companies that work in auto tier 1 procurement for the auto tier 1 supply chain are always looking for auto parts manufacturers who can supply stamped and formed automotive parts that meet the standards for OEM automotive manufacturing.

The high quality standards for automotive components manufacturing are set by the International Automotive Task Force (IATF), with IATF 16949 being the globally accepted compliance certification for vehicle manufacturing.

Which suspension components do Tier 1 automotive suppliers need?

Demand for suspension components for tier 1 automotive assembly lines is dominated by the need for high quality control arms (A-arms), and upper and lower arm wishbones with tooling and stamping presses that are suited to the high tensile steel forming required for the majority of Tier 1 automobile assembly lines in 2025.

• Control arms / A-arms
• Upper arms
• Lower arms
• Suspension Wishbones

Standards for metal stamping of critical suspension parts

Metal stamping is a well established technology for rapid mass produced auto parts manufacturing, but it is important to make a distinction between the standards required for manufacturing critical components like suspension control arms and the less stringent requirements for non-structural body parts, trim and components.

Many metal stamping service providers can readily manufacture the majority of stamped and welded assemblies for automotive manufacturing, but the critical safety and quality requirements for tier 1 suspension components add a significant layer of responsibility, auditing and expertise that requires IATF certification as a minimum to ensure compliance with tier 1 manufacturing standards.

How are auto suspension components made?

There are two core production processes for auto suspension component manufacturing. Suspension components can be formed by metal stamping and made into welded assemblies, or machined from forged or cast billets using CNC lathes.

The growth of high tensile steel metal stamping services and technologies has made welded assemblies made from formed high tensile steel components an attractive option for Tier 1 OEM automotive assembly in 2025. Successful long-term Tier 1 supply chain partnerships are now offering high tensile steel parts as a standard suspension component metal stamping service.

What are the advantages of metal stamping suspension components?

The use of CAD/CAE/CAM technologies combined with sophisticated robotic metal stamping presses and tooling enable the rapid production of high tensile formed suspension parts that have some advantages over other auto tier 1 supply chain technologies.

High tensile component stamping

High tensile steel (SPFH590 / Grade 60) metal stamping to make the parts for suspension component welded assemblies enables auto parts manufacturers to reduce weight without compromising on strength, and to do this in components that have a significant impact on vehicle performance, especially vehicle handling and steering responsiveness.

• High tensile metal stamping for strong, lightweight suspension components
• Robotic stamping and welding speeds up manufacturing
• CAD/CAE/CAM technology enables reliable, consistent forming solutions

Lighter suspension components to meet new industry demands

The drive in automotive manufacturing towards reduced weight is in part due to increasing demand for fuel efficient vehicles, and to increase the range of EVs. In lighter vehicles we are likely to see an increase in the use of high tensile automotive metal stamping for all types of suspension components.

The limitations of metal stamping compared to CNC machining using high strength alloys mean that we will continue to find a combination of automotive metal stamping and CNC machining being used to manufacture auto suspension components for the foreseeable future, but the comparative production speed of metal stamping makes it an attractive option, especially with high tensile steels.

Auto tier 1 procurement of suspension components

Auto tier 1 procurement supply chains can only be served by auto parts manufacturers who are as proficient at inventory and logistics management as they are at tooling manufacturing and running automotive metal stamping presses to meet the standards for metal stamping service that are required by tier 1 auto brands.

Automotive suppliers seeking to remain competitive in supply chain tiers for international car assembly lines need to be competent and efficient across all stages of production. From design through production to just-in-time delivery to automotive assembly plants, auto tier 1 procurement requirements can only be met by auto parts manufacturers who are at the top of the game across every aspect of their business.
