Raw material inspection, also known as Incoming Quality Control (IQC), is a vital process to ensure that only materials meeting strict quality standards enter production. By verifying factors such as quality, consistency, dimensions, and compliance with international or national standards, IQC confirms that each shipment matches the specifications agreed upon with the supplier. This process protects your production line from defects, prevents costly rework, and builds trust with suppliers which lays the foundation for consistent, reliable product quality throughout the supply chain.
Our Two-Stage Quality Assurance Approach
Stage ONE: Before the Contract: Supplier Qualification
Before we even sign a purchase agreement, we ensure that our suppliers and their materials are fully qualified:
1. Supplier Evaluation & Audit: We assess the supplier’s production capabilities, quality management systems (e.g., ISO standards), and past performance.
2. Sample Testing & Material Approval: Initial samples are tested for critical factors such as chemical composition, durability, and compliance with standards (e.g., ISO, ASTM).
3. Defining Quality Standards: Together with the supplier, we establish precise material specifications, acceptance criteria, and inspection methods.
4. Contract Agreement: All quality requirements are documented in the purchase contract to ensure accountability.
Stage TWO: After Material Arrival: Incoming Quality Control (IQC)
Our IQC process includes:
1. Pre-Inspection Planning: Reviewing purchase orders, specifications, and standards to determine inspection requirements.
2. Visual Inspection: Detecting physical defects such as damage, contamination, or irregularities.
3. Dimensional & Specification Checks: Measuring properties like thickness, weight, and dimensions with precision tools.
4. Laboratory Testing (if required): Performing chemical, mechanical, or performance tests in-house or through certified third-party labs.
5. Sampling & Batch Testing: Applying standardized sampling methods such as AQL to ensure representative testing.
6. Documentation & Reporting: Recording detailed inspection data, photos, and results for full traceability.
7. Supplier Feedback & Continuous Improvement: Sharing findings with suppliers to drive ongoing quality improvements.
