CQI-30 is one of the dedicated process system assessment standards published by AIAG (Automotive Industry Action Group), focusing on rubber processing systems. Its full name is:
CQI-30: Special Process – Rubber Processing System Assessment (RPSA)
Standard Name CQI-30 Rubber Processing System Assessment
Current Version 2 (Published in November 2020)
The main goal of CQI-30
Reduce defects in the processing process, such as bubbles, scorch, shrinkage, dimensional loss of control, etc.
The structure of CQI-30
CQI-30 is divided into two parts:
1️⃣ Mixing & Molding System Assessment
2️⃣ Extrusion System Assessment
Users can select the corresponding module for assessment (or both) according to their own process.
1️⃣ Mixing & Molding System Assessment
Applicable to rubber compounding, mixing (such as internal mixing, open mixing), compression molding (molding, injection molding) and other processes.
Ingredient Control Accurate metering error is controlled within ±1%, with records
Mold Management Mold cleaning, numbering, anti-sticking agent use, periodic maintenance records
Inspection Items Appearance, hardness, size, specific gravity, compression set, tensile strength, etc.
2️⃣ Extrusion System Assessment
Applicable to rubber extrusion (such as sealing strips, hoses, profiles, etc.) and vulcanization systems.
Dimension control Width, height, thickness, etc. require online dimension detection
Error prevention measures Anti-mixing mechanism when changing formula, machine, sequence
CQI-30 adopts the standard CQI system scoring method:
Recommended frequency: Conduct a complete self-assessment every 12 months
CQI-30 Applicable Product Examples
