Quality Control System Five Inspection Stages Every Pad Printing Silicone Batch Must Pass

Every batch of raw materials including silicone rubber, filler and catalyst is tested for viscosity, purity, moisture and heavy metals before entering the warehouse. Only qualified materials proceed to production.

Production Monitoring

Automated mixing equipment operates under precise parameters with full record keeping. Viscosity is sampled during mixing, and a final check confirms quality before filling.

Finished Product Testing

Each batch undergoes hardness, viscosity, operation time, cure time, tensile strength, tear strength, elongation and density testing. All must meet specifications before COA report issuance and shipment.

Sample Retention

Samples from every batch are retained for two years, enabling quick retesting if customer issues arise. Full traceability links raw materials, production, testing and shipping records.

Continuous Improvement

Monthly quality meetings analyze data and feedback to drive improvements. Factory pass rate stays above 99 percent, earning trust across 138 countries.
