SEECIN Quality Control (QC) Process

SEECIN implements a strict, full-process quality control system to ensure that all products meet customer requirements and international standards. Quality management is embedded in every stage, from raw material procurement to final product delivery, with the following key steps:
01

Supplier & Raw Material Quality Control

Supplier qualification audits to ensure compliance with company quality standards.

Incoming raw material inspection, including checks on appearance, dimensions, and composition, to verify compliance.

Key materials require test reports and are subject to periodic reviews.

02

Production Process Quality Control

First Article Inspection (FQC): Comprehensive inspection of the first batch before full-scale production to ensure compliance with process standards.

In-Process Quality Control (IPQC): Regular inspections during production to detect and correct defects in real-time.

Final Inspection (OQC): Comprehensive testing of finished products, including appearance, functionality, and packaging integrity.

03

Equipment & Process Control

Routine maintenance of production equipment to ensure stability and precision.

Strict parameter control for key processes such as injection molding, stamping, and glass blowing.

Use of automated testing instruments during production to guarantee product consistency.

04

Packaging & Finished Product Inspection

Visual and functional inspection before packaging to ensure product quality and completeness.

Compliance of packaging materials with environmental and shipping standards.

Random sampling of finished products before storage or shipment to ensure compliance.

05

Quality Issue Handling & Continuous Improvement

Immediate root cause analysis and corrective actions for detected quality issues.

Systematic recording and periodic analysis of quality concerns to improve production processes and standards.

Customer feedback mechanism to promptly address complaints and enhance product quality.

SEECIN leverages a digital quality management system to enable real-time data collection, analysis, and decision-making, ensuring a closed-loop quality control system. This guarantees an efficient, stable production process and consistently high-quality products for our customers.
