Matte + Long-life Continuous Filtration

SUNGJINLOGIS manages particles and suspended solids in the bath through long-life continuous filtration, maintaining uniform matte appearance and stable color consistency.

Long-life Continuous Filtration

Continuously reduces fine particles and suspended solids in real time to lower the risk of surface defects (specks/haze/color stains).

Appearance & Color Consistency

Maintains bath cleanliness and stability to minimize variation in matte texture and color.

Production Stability

Reduces process drift in continuous production to manage defect rates and rework risk.

Control Points

A summary of key control items for consistent matte/semi-matte appearance.

• Reduce fine particles and suspended solids generated during operation through continuous recirculating filtration

• Maintain cleanliness by operating based on filtration flow rate and turnover (circulation volume) standards

• Respond immediately to differential pressure (ΔP) rise with filter replacement/cleaning (clogging/saturation control)

• Prevent re-suspension by regularly removing sludge and settled solids from the tank bottom

• Minimize analytical variability by standardizing sampling location and timing (data reliability)

• When needed, strengthen carbon treatment/filtration to reduce organic contamination and fine particles simultaneously

Verification Evidence

We ensure process reliability through measurable data and systems.

• In-house thickness/appearance/adhesion evaluation and data-based management before/after condition changes

• Support reliability testing such as salt spray (including CASS when required), thermal shock, and heat & humidity cycles

• Secure process traceability through records such as filter replacement history, differential pressure (ΔP), and flow rate

• Process control and 대응 based on quality system requirements (SQ/ISO, etc.)

Typical Applications

Applied to product groups with high appearance-quality requirements.

• Matte appearance–sensitive parts such as automotive interior trims and buttons

• Products with high appearance requirements such as mobile brackets and decorative parts

• Parts where stabilizing downstream nickel/chrome appearance quality is critical
