6mm Aluminum Stamping for Automotive Copper-Aluminum Busbar

1. Project Overview

For this automotive project, Innoway Precision manufactured a 6mm thick aluminum component used in a copper-aluminum welded busbar assembly.

The part is used in an automotive electrical connection system, where stable dimensions, consistent forming quality and reliable assembly fit are important for downstream welding and final assembly.

• Product: Copper-Aluminum Welded Busbar Component
• Application: Automotive
• Material: Aluminum
• Thickness: 6.0 mm
• Process: Stamping, forming and inspection
• Inspection: In-process inspection + dedicated gauge inspection

Unlike conventional thin sheet metal parts, a 6mm aluminum component requires stronger forming capability and better control of dimensional consistency.

2. Project Challenges

The main challenge was not simply forming the 6mm aluminum plate, but maintaining stable geometry throughout production.

For this type of automotive component, several factors are important:

• Thick aluminum requires higher forming force.
• Burr and edge condition must remain controlled.
• Formed dimensions must remain consistent between batches.
• Critical features must fit correctly in subsequent welding and assembly.

Any excessive dimensional variation could affect the positioning of the copper-aluminum busbar during the next manufacturing stage.

3. Our Solution

Based on the product structure and application requirements, our engineering team developed a controlled manufacturing process for the 6mm aluminum component. The project focused on three areas:

Stable forming
The forming process was optimized to maintain consistent part geometry and reduce variation during production.

Process inspection
Key dimensions were monitored during manufacturing instead of relying only on final inspection.

Dedicated gauge inspection
Critical features were checked using dedicated inspection gauges to ensure repeatable fit and dimensional consistency.

The objective was simple: keep the process stable and make every part suitable for the next assembly stage.

4. Project Result

The project achieved stable production of the 6mm aluminum stamped component, with consistent forming quality and reliable critical dimensions.

The finished parts meet the requirements for subsequent copper-aluminum welding and automotive assembly.

For us, thick metal stamping is not only about press capacity It is about maintaining consistent quality from the first part to mass production.

If you are developing an automotive busbar, battery connection component or other custom thick aluminum part, our engineering team can review your drawings and manufacturing requirements.
