Case Study 17｜REACH-Compliant Automotive Key Lock & Metal Logo Manufacturing for a German Brand

Introduction

At XY-GLOBAL, we specialize in Automotive Parts Manufacturing, providing precision CNC machining, metal logo production, and high-standard surface finishing for global brands.
This case study shares how we supported a German automotive accessories company with REACH-compliant key lock and logo manufacturing.

Below is our behind-the-scenes video for this project：

Customer Background

Our client is a well-known German automotive accessories manufacturer seeking a partner with strong Automotive Parts Manufacturing capabilities.
Their requirements included:

• High-quality key locks

• Brushed interior trim finishing

• Custom metal logos for leather goods

• Fully REACH-compliant manufacturing

• Consistent surface appearance and repeatable production

They needed a supplier who could combine engineering innovation with stable mass-production capability.

Engineering Challenges

1. Brushed Finish Required on Interior Trim

The customer requested a uniform brushed inner-surface finish, which is difficult to achieve directly in typical Automotive Parts Manufacturing processes.
Direct brushing resulted in:

• Poor repeatability

• High risk of deformation

• High cost at mass production scale

This required a more advanced finishing solution.

2. Logo Support Legs Too Hard & Damaging Leather

During testing, the client reported:

• Metal logo support legs were too stiff

• Risk of scratching premium leather

• The material needed more flexibility

Solving real-use problems is a core part of effective Automotive Parts Manufacturing, so our engineering team reacted immediately.

XY-GLOBAL’s Engineering Solutions

1. “Circular Background Plate Bonding” for Brushed Trim

To ensure consistent quality while maintaining manufacturability, we developed an innovative solution commonly used in premium Automotive Parts Manufacturing:

✔ Add a brushed circular background plate
✔ Precisely bond the plate to the interior trim
✔ Achieve a perfect brushed effect
✔ 100% REACH-compliant surface finishing

This improved both appearance and production stability.

2. Optimized Logo Support Leg Material：Soft Copper

To prevent leather damage, XY-GLOBAL revised the material:

• Hard alloy → Soft copper

• Enhanced flexibility

• Eliminated scratching risk

• Improved installation for end users

This practical adjustment is a typical value-added service in modern Automotive Parts Manufacturing workflows.

Sample Testing & Final Results

After multiple rounds of prototype adjustments and engineering validation, the final product met all customer expectations:

• Highly consistent brushed surface

• Zero deformation issues

• Perfect bonding effect

• Soft copper legs with safe contact on leather goods

• Full REACH-compliant Automotive Parts Manufacturing process

• 100% pass rate in final inspection

The German customer visited our China facility this month and praised our technical capability, professionalism, and process control.
