Quality Control

Acrylic Craftsmanship Quality Control Standard

B2B Global Supply Chain Compliance & Excellence Protocol

1. Purpose and Scope

This document outlines the strict Quality Control (QC) Standard operating procedures enforced at our manufacturing facility. As a premier B2B manufacturer of premium acrylic gifts, awards, displays, and custom merchandise, we are dedicated to delivering structural integrity, optical clarity, and regulatory compliance. This standard ensures that all shipped lots satisfy both international trade requirements and high brand aesthetics.

2. Material Integrity and Inspections

Quality begins with premium raw materials. We exclusively source non-toxic, 100% virgin methyl methacrylate (MMA) monomer cast acrylic sheets. Every incoming material batch undergoes rigorous spectroscopic testing to guarantee UV resistance, zero yellowing degradation, and optimal impact resistance. Our materials strictly comply with global environmental directives, including REACH, RoHS, and California Proposition 65, eliminating heavy metals and hazardous phthalates.

3. Multi-Stage In-Line Quality Gates

Our comprehensive production flow is monitored through a four-tier inspection structure: IQC (Incoming), IPQC (In-Process), FQC (Final Product), and OQC (Outgoing). Precision laser cutting and CNC routing operations maintain tight dimensional tolerances within ±0.1mm. Technicians systematically audit mechanical tooling calibrations every four operating hours. Post-machining, all diamond and flame-polishing stages are visually inspected under standardized 1200-lux light stations to eliminate microscopic scratches, tool marks, or surface distortion.

4. Defect Classification and AQL Limits

We execute statistical sampling in strict accordance with the ISO 2859-1 (ANSI/ASQ Z1.4) international standard, utilizing Acceptable Quality Limit (AQL) thresholds optimized for premium giftware. Critical defects (e.g., sharp edges, structural cracks, or hazardous burrs) carry a 0% tolerance. Major defects (e.g., visible interior bubbles, cloudiness, or print misalignment exceeding 0.2mm) are capped at AQL 1.5. Minor imperfections are managed under AQL 4.0
