## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are recommended for pharmaceutical tablet press seal gaskets?
**A**: Our seal gaskets are manufactured from food-grade silicone, pharmaceutical-grade EPDM, PTFE (Teflon), and fluoroelastomer (Viton) to ensure compatibility with pharmaceutical applications and prevent contamination.

### Q: How do these gaskets prevent powder leakage in tablet press feed frames?
**A**: The gaskets feature a specialized design with an anti-extrusion ring, compression zone, and sealing lip that creates a tight seal between components, effectively containing powders and preventing leakage during tablet compression operations.

### Q: Why are these sealing components critical for pharmaceutical manufacturing?
**A**: These gaskets are essential for maintaining product purity, preventing cross-contamination between batches, ensuring consistent tablet quality, and complying with pharmaceutical manufacturing regulations like cGMP.
