3 Critical Pain Points in Traditional Silicone Molding
❌ High Defect Rates
Traditional compression molding leads to air entrapment and inconsistent curing, causing up to 15% defect rates in high-precision applications. (Source: Fraunhofer Research, 2025)
❌ Slow Production Cycles
Conventional methods require 3-5x longer cycle times compared to liquid injection molding, delaying time-to-market for urgent projects.
❌ Limited Design Flexibility
Complex geometries (e.g., under-cut seals, multi-material overmolds) are nearly impossible with outdated tooling, restricting innovation.
