Why Transparent Plastic Parts Fail (And How We Prevent It)
Most suppliers treat transparent molding like standard injection molding—it is not.

Common Failures:
Bubbles or silver streaks (moisture contamination)
Flow lines or haze (unstable melt flow)
Stress whitening or cracking (internal stress)
Surface defects (poor mold polishing)
Our Engineering Approach:
1. Material Drying Control
We control resin moisture below critical thresholds using industrial drying systems and monitored cycles.

2. Mold Surface Perfection
Mirror polishing to SPI A1 standard ensures optical clarity and surface replication accuracy.

3. Process Window Optimization
We fine-tune temperature, pressure, and injection speed to avoid degradation and flow defects.

4. Mold Flow & Venting Design
Optimized gating and venting eliminate trapped air and ensure uniform filling.

Material Selection Guide (Choose the Right Transparency)
Material Best For Key Advantage Limitation
PMMA (Acrylic) Optical parts, lenses Highest clarity Brittle
PC (Polycarbonate) Impact-resistant parts High strength Stress sensitivity
PETG Medical & packaging Easy processing Lower heat resistance
PS Low-cost transparent parts Economical Low durability
