1. Project Background

A holiday gift brand approached XY-GLOBAL with concerns about surface durability in their stainless steel ornaments. Their previous supplier produced mirror-polished pieces that were easily scratched, and fingerprints were highly visible on the surface. Because these ornaments were part of a premium seasonal collection, the client required a more reliable finishing process using SUS304 stainless steel.

2. Our Material Capability

XY-GLOBAL supports a wide range of stainless steel materials commonly used in decorative hardware, aesthetic components, and precision accessories:

• SUS304 – General-purpose stainless steel with excellent corrosion resistance and formability

• SUS316L – Superior corrosion resistance for medical, marine, and high-end consumer products

• SUS420 – High hardness and wear resistance, suitable for blades and mechanical components

• SUS630 (17-4PH) – High-strength precipitation-hardening stainless steel for structural parts

This project specifically uses SUS304, chosen for its balance of corrosion resistance, appearance, and process compatibility.

3. Our Manufacturing Solution

After receiving the client’s samples, our engineering team analyzed the root cause of the scratch issue and determined that the previous supplier lacked adequate post-polish surface protection. To improve durability and appearance, we optimized the process as follows:

1) High-Precision Laser Cutting (SUS304 Sheet)

We cut the SUS304 stainless steel sheet using high-precision laser processing to ensure clean edges, accurate outlines, and minimal heat-affected zones.

2) Mirror Polishing (Bright Polished Finish)

We polished the ornaments to achieve a reflective, high-gloss mirror surface according to the client’s aesthetic requirements.

3) Anti-Fingerprint Coating (Key Enhancement)

To significantly improve durability, we applied a transparent anti-fingerprint coating designed to:

• Increase resistance to scratches and micro-abrasion

• Reduce fingerprint visibility

• Maintain a clean surface during handling and packaging

• Improve long-term appearance and customer satisfaction

Comparative testing confirmed that the upgraded finishing process performed markedly better than the previous supplier’s product.

4. Client Feedback

The client reported highly positive results after receiving our samples and subsequently moved the product into production:

“All feedback has been very positive. You are by far my favorite vendor to work with. Communication is excellent, and every product delivered meets our expectations perfectly.”

Following the success of the ornament project, the customer plans additional CIM and stamped metal projects.

5. Technical Overview

• Material: SUS304 stainless steel

• Supported Materials: SUS304, SUS316L, SUS420, SUS630

• Processes: Laser cutting + mirror polishing

• Surface Finish: Anti-fingerprint coating

• Application: Holiday ornaments, keychain accessories, decorative parts

• Specification: Appearance-based customization; dimensional requirements vary by design

6. Quality Control & Inspection Standards

To ensure every SUS304 ornament meets the customer’s expectations, XY-GLOBAL implements strict inspection procedures:

Incoming Material Inspection

• Verification of SUS304 material certification

• Thickness, flatness, and surface condition checks

In-Process Quality Control

• Laser cutting accuracy inspection

• Edge quality check to prevent burrs

• Polishing uniformity and reflectivity assessment

Surface Treatment Validation

• Adhesion testing for anti-fingerprint coating

• Micro-abrasion scratch resistance comparison

• Fingerprint visibility reduction evaluation

Final Quality Inspection

• 100% visual inspection under controlled lighting

• Packaging protection to avoid friction during transport

These steps ensure that each ornament arrives in perfect condition without scratches or fingerprints.

7. Application Scenarios & Customization Capability

Although this project focuses on a holiday ornament, the same manufacturing techniques and surface expertise can be applied to various industries:

Suitable Product Categories

• Fashion accessories

• Premium brand packaging components

• Keychain and jewelry hardware

• Decorative metal plates and tags

• Custom event merchandise

• Lifestyle and home décor pieces

Customization Options

• Material selection: SUS304 / SUS316L / SUS420 / SUS630

• Finishes: mirror polish, brushed finish, matte sandblasting, PVD color coating

• Additional processes: engraving, laser marking, CNC profiling, bending, stamping

• Logo customization for branding or retail packaging

XY-GLOBAL supports low-volume flexible production as well as stable long-term mass production, allowing customers to prototype and scale efficiently.

8. Conclusion

The upgraded manufacturing process for the SUS304 mirror-polished ornaments not only solved the customer’s scratch and fingerprint concerns but also enhanced the product’s perceived value and consistency. By combining precise laser cutting, high-quality polishing, and an anti-fingerprint protective coating, XY-GLOBAL delivered a final product that exceeded customer expectations and strengthened long-term collaboration.
