Medical Grade Liquid Silicone Rubber (LSR) Injection Molding | ISO 13485 Certified Factory

Challenges in Medical Mask Production In medical-grade product production, especially for breathing masks, functionality, safety, and durability are critical. Henry Precision faced several challenges in designing medical masks using Covestro PC-2458 (a high-temperature-resistant polycarbonate) and JAPEN Shin Etsu2090-40 (liquid silicone rubber, LSR). These materials meet FDA’s biocompatibility requirements and provide the necessary support, sealing properties, and performance. Material Compatibility and Bonding Issues Bonding liquid silicone to plastic components is essential for maintaining structural integrity. The high fluidity of liquid silicone can cause gas traps, degumming, and non-stick defects. To address this, the adhesive process had to ensure a strong, reliable

In the production of sealing rings for medical devices, maintaining precision and ensuring high-quality performance is crucial. Henry Precision recently encountered several challenges while manufacturing a sealing ring with WACKER 3038-70 silicone material. The product’s small size, internal instability, and complex structure required advanced design, meticulous attention to detail, and high-precision mold processing.   Challenges Internal Size InstabilityThe sealing ring had a relatively small internal size, which was prone to instability. This caused issues such as partial silicon filling, leading to potential quality defects. The solution required careful mold design and machining precision to ensure stable production. Multiple Cavities and

For this project, Henry Precision was tasked with producing a respiratory mask using a rapid prototype mold. The product was made from Liquid Silicone Rubber (LSR) and required precise manufacturing to meet high standards. The mold size was Wx300 Lx300 H (mm), and it featured a cavity of 1. The delivery time was set at 10 days to meet the customer’s needs.
