PRODUCT PORTFOLIO

Eight solution areas across the surface treatment line

From cleaning and activation to plating, conversion coating, post-treatment, and bath-management equipment, we review chemicals and support around the full process flow.

Pretreatment

Substrate-specific degreasing, pickling, etching, desmut and activation establish a clean, active surface for subsequent plating and coating.

Steel and iron · Copper and copper alloys · Aluminum and its alloys · Zinc and zinc-plated surfaces · Nickel underlayers

Electroplating

Copper, nickel, tin, zinc, chromium, silver and gold baths are managed together with current, additives, agitation and filtration.

Steel and iron · Copper and copper alloys · Zinc-based surfaces · Nickel underlayers · Connectors and electrical contacts

Electroless plating

Metal, reducer, pH, temperature and bath loading are controlled to maintain deposition rate and stability in electroless nickel and copper.

Steel and iron · Copper and copper alloys · Aluminum and its alloys · Catalyzed non-conductors · Electronic and precision parts

Aluminum anodizing

Alloy-specific chemical polishing, etching and desmut are managed through anodizing, dyeing, sealing and nickel leach-out removal.

Aluminum and aluminum alloys · Aluminum sheet and machined parts · Precision-machined parts · Decorative components · Functional oxide-film parts

Conversion coating

Phosphate, chromate and zincate treatments for steel, zinc and aluminum are reviewed with pretreatment and downstream processes.

Steel and iron · Zinc and zinc-plated surfaces · Aluminum and its alloys · Copper and copper alloys · Substrates before painting or plating

Post-treatment & specialty chemicals

Anti-tarnish, protective coatings and specialty cleaning/removal processes improve appearance, corrosion resistance and storage stability after plating.

Copper and copper alloys · Silver-plated surfaces · Nickel- and tin-plated surfaces · Contacts and connectors · Decorative and functional parts

Basic chemicals

Sulfuric, hydrochloric and nitric acids, caustic soda and other line chemicals are managed by specification, concentration, replenishment and lot.

Sulfuric acid · Hydrochloric acid · Nitric acid · Caustic soda · Acid and alkaline raw materials for finishing

Filtration equipment & related systems

Circulation, filters and carbon-treatment conditions are reviewed by process to control particles, sludge and organic contamination in plating baths.

Plating-bath filter systems · Filter cartridges and media · Chemical-resistant pumps and piping · Carbon-treatment systems · Tank and agitation equipment

CORE PROCESS

Focused control for processes prone to quality variation

Surface treatment quality depends on the connection between pretreatment, bath composition, temperature, agitation, filtration, rinsing, and post-treatment.

Electroless nickel

We review pH, temperature, metal concentration, reduction reaction, and bath stability to support uniform deposits.

Defect diagnosis

Aluminum anodizing

Alloy-specific pretreatment, film formation, dyeing, sealing, and color variation are reviewed as one process flow.

Etching & desmut

Zinc & zinc-nickel

Alloy composition, current conditions, conversion coating, and post-treatment are considered for corrosion resistance and appearance.

DEFECT SOLUTION

Technical support that narrows causes from defect symptoms

Defect photos, timing, operating conditions, and recent changes help prioritize whether pretreatment, the plating bath, equipment, or post-treatment should be checked first.

TECHNICAL SUPPORT MODEL

Connected support from first inquiry to result review

A field issue is rarely explained by one number. We begin with the substrate and process history, then prioritize the factors most likely to influence quality.

01
Process intake
We collect the substrate, process sequence, chemicals in use, defect photos, timing, and recent changes.
INPUT · Photos / conditions / history
02
Cause grouping
Pretreatment, bath chemistry, equipment, rinsing, and post-treatment are separated into priority cause groups.
CHECK · Process priorities
03
Condition review
We review the analysis items, chemical additions, condition adjustments, and sequence for a controlled trial.
ACTION · Add / adjust / test
04
Result follow-up
Trial results and recurrence are reviewed to organize the next control items and inspection interval.
FOLLOW-UP · Verify results

MANUFACTURING · R&D · QUALITY

Local manufacturing, analysis, and quality in one system

A connected flow from raw-material checks and production to in-process inspection, final inspection, and LOT management supports reliable supply.
