How Addition Curing Silicone Is Transforming Roman Column Manufacturing

2026,08,20

Addition curing (platinum-cured) silicone has become the material of choice for Roman column and classical architecture mold making, driven by demand for higher precision and lower per-unit costs.

Market Trends: Customization favors silicone molds for small-batch production. Tightening FDA/EU regulations require clean-curing materials. Molds lasting 800-1000+ casts beat condensation-cure alternatives (200-300 casts) on cost.

Technical Details: Hong Ye Silicone offers E Series (translucent, 15–50 Shore A) and Q Series (fully transparent). HY-E630 (30A) is recommended for Roman columns. Key specs: tear 16-25 kN/m, tensile 4.2-6.0 MPa, elongation 300-500%, shrinkage ≤0.1%, ratio 1:1 or 10:1, pot life 25-65 min, cure 3-7h at 25°C, temp -60°C to 200°C. Certified ISO 9001, FDA, REACH, RoHS, UL, CE.

Key Advantages:

<0.1% shrinkage — 1m mold deviates <1mm

1,000+ casts cuts per-unit cost by 70%

Smooth finish reduces post-processing

1:1 for large molds; 10:1 for fast turnaround

FDA-certified, no harmful residues

ISO 9001 batch-to-batch consistency
