Analysis of the main factors affecting the shrinkage rate of liquid silicone molding
Author： Published：2026-06-25 Clicks：
Factors affecting LSR shrinkage rate
Key factors: 1) Material formulation (1.5%-3.0% typical), 2) Mold temperature (higher = lower shrinkage), 3) Injection/holding pressure, 4) Part geometry and wall thickness, 5) Post-curing effects. Proper mold design with shrinkage allowance is essential.
