3 Critical Problems You Face with LSR Molding Suppliers
❌ High Tooling Costs & Long Lead Times
Traditional LSR molds cost $20,000–$100,000 with 12–20 week lead times. 78% of buyers report delays due to poor mold design or material issues (Reddit Industry Discussion).
❌ Inconsistent Quality & High Defect Rates
Poor process control leads to flash, air traps, or incomplete curing. Studies show 15–25% defect rates in offshore LSR production without proper simulation (MDPI Research).
❌ Limited Customization & Scalability
Many suppliers lack multi-component molding or overmolding capabilities. 62% of medical device buyers struggle to find suppliers for complex LSR+plastic hybrids (MDPI Polymers Study).
