                Engineering Challenges and Solutions<\/h2>\n

                LSR to PC Bonding Stability<\/h3>\n

                Silicone rubber has natural chemical inertness, making adhesion to PC challenging. This is solved through:<\/p>\n

                  \n
                • Self-bonding medical-grade LSR formulations<\/li>\n
                • Surface activation or primer treatment on PC<\/li>\n
                • Controlled mold temperature for optimal chemical bonding<\/li>\n<\/ul>\n
                  \n

                  Thermal Processing Balance<\/h3>\n

                  PC and LSR have different thermal requirements.<\/p>\n

                    \n
                  • PC has a limited heat deflection temperature range<\/li>\n
                  • LSR requires high curing temperature for vulcanization<\/li>\n
                  • Requires optimized mold temperature and high-heat PC materials<\/li>\n<\/ul>\n
                    \n

                    Precision Flash Control<\/h3>\n

                    Due to the very low viscosity of LSR:<\/p>\n

                      \n
                    • Mold tolerance must be controlled at micron level<\/li>\n
                    • High-precision tooling is required to prevent flash formation<\/li>\n
                    • Critical for medical-grade surface quality<\/li>\n<\/ul>\n
                      \n

                      Foire aux questions<\/h2>\n

                      What is the benefit of LSR overmolding compared to traditional assembly?<\/h3>\n

                      LSR overmolding eliminates separate sealing components such as O-rings, reducing leakage risk and improving long-term stability.<\/p>\n

                      Is the product suitable for repeated sterilization?<\/h3>\n

                      Yes, it is designed for repeated autoclave sterilization between 121\u00b0C and 134\u00b0C without performance degradation.<\/p>\n

                      Does the silicone become hard or degrade over time?<\/h3>\n

                      Medical-grade LSR maintains elasticity and mechanical stability under long-term use.<\/p>\n

                      Le design peut-il \u00eatre personnalis\u00e9 ?<\/h3>\n

                      Yes, customization is available for geometry, hardness, color, and sealing structure based on application requirements.<\/p>","protected":false},"excerpt":{"rendered":"
