WebA congenital diaphragmatic hernia (CDH) happens if the diaphragm does not form completely before birth. This leaves a hole between your baby’s belly (abdomen) and chest. Organs that should be in the belly go through the hole up into the chest, crowding the lungs. The condition is pronounced kun-JEN-ih-tul dy-uh-fruh-MA-tik HER-nee-uh. WebDiaphragm forming uses sheets of reuseable silicone as a carrier for COMFIL® fabrics between a hot platen section and a forming section. The process transforms COMFIL®fabrics into parts with very low air pressure. The one side tooling remains cold, and is therefore extremely inexpensive. Key Processing Points:
