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.
