A typical silicone mold used in urethane casting can produce 15 to 30 parts, depending on material, geometry, and casting conditions. Silicone molds for urethane casting usually make 20 to 50 parts, though some last 25 to 300 cycles with the right silicone grade, part shape, and handling. In many shops, silicone tooling averages about 20 to 25 parts before replacement. Your urethane casting mold life depends on geometry, silicone type, resin aggressiveness, cure temperature, and demolding stress. If you want realistic output estimates, you need to judge each of these variables with care. Key Takeaways Silicone molds usually make…
You might ask how long silicone mold life is when you use molds. People use molds for baking, crafts, or big projects. Most silicone molds last between 200 and 3,000 uses. Basic peroxide silicone molds last about 200 times. High-quality platinum silicone molds last over 3,000 times.
