Robotic Pretreatment
SUNGJINLOGIS standardizes process conditions through robotic pretreatment automation, ensuring stable plating adhesion and repeatable cosmetic appearance.
Standardized Operating Conditions
Standardizes key variables such as time, temperature, and concentration to minimize operator-to-operator variation.
Repeatability-Driven Quality
Secures pretreatment uniformity to reduce color and appearance variation in downstream processes.
Production Stability
Reduces process drift in continuous production to manage defect risk and rework.
Control Points
A summary of key control items that create pretreatment uniformity.
• Operate each pretreatment tank with standardized recipes (time/temperature/concentration)
• Maintain treatment uniformity by checking agitation, filtration, and circulation conditions
• Manage rinse water quality and contamination to minimize drag-out and contamination risk
• Control contact and contamination factors by standardizing rack/fixture cleaning and maintenance
• Reduce process variation by standardizing robot motions (immersion/transfer/drip time)
Verification Evidence
We build process confidence through measurable data and systems.
• In-house evaluation of thickness, appearance, and adhesion with data-based history tracking
• Quality systems in operation: SQ / ISO 9001 / customer requirement compliance
• When issues occur: root-cause analysis → condition correction → recurrence prevention (reflected in SOPs and checklists)
Typical Applications
Applied to product groups with strict appearance-quality requirements.
• Automotive interior parts: supports demanding requirements for appearance and tone consistency
