Challenges Greystone’s Functional Plating Can Help Solve
Vertical Integration
for Consistent Quality
When machining and plating are handled by separate vendors, accountability can become unclear, often leading to delivery delays and quality issues.
Greystone has established a vertically integrated system that handles the entire process in-house, from machining through finishing. This eliminates handoff issues between processes and transportation wait times, reducing the coordination burden on quality assurance and production control teams.
Uniform Coating Thickness
with the PPS® System
In volume production runs of several hundred thousand to several million parts, processing large batches can cause coating thickness variation and increase the risk of defects reaching downstream operations.
Problems caused by uneven coating thickness can be resolved with the fully automated PPS® system. Because the system measures and controls individual parts in real time, it can automatically isolate nonconforming products. The system maintains uniformity with a process capability index (Cpk) of 2 or higher and helps prevent assembly defects caused by out-of-tolerance dimensions.
Meeting OEM Requirements
with IATF Certification
If Tier 1 and Tier 2 suppliers cannot meet the stringent quality requirements of vehicle OEMs, they risk losing repeat business.
Greystone is IATF 16949 certified at all of its global plants*. APQP-based management and automated inspection equipment help meet customer audit requirements. By meeting the 4 PPM defect-rate requirement, Greystone helps customers maintain their business relationships with vehicle OEMs.

Functional Plating Services
by Industry
and Component Type
Semiconductor Components
“We need a shop for difficult plating others declined.”
Japan, est. 1931
- Precious Metal Plating
for Micro Components - Mitsuya supports uniform precious metal plating on parts down to 0.1 mm in diameter. This can help improve precision and durability in semiconductor inspection equipment.
- High-Adhesion Plating
for Tips and Contacts - Mitsuya has developed an in-house process for titanium and tungsten that does not require heat treatment. It can support high-adhesion plating on pin and card contact areas.
- Support for New Product Development
- Engineers can consult Mitsuya before semiconductor IC specifications are finalized and verify performance through prototypes. This can help reduce development risk and rework costs.
- Electronics and Telecommunications
- Semiconductor Inspection Equipment
- Space Development
