Floating core or projectile injection technology (PIT) is a special technique in the field of fluid injection technology (FIT) which involves the injection of a medium that presses a projectile through the still plasticized melt so as to create a hollow cavity. The medium pushes the projectile through the melt. The resulting wall thickness levels are defined and formed by the projectile. This process is characterized by the following benefits:
- Prevention of material clusters reduces cycle times
- Constant cavity diameter across the part
- Supports pipe branching
- Supports the production of parts with variable and uneven diameters
Our team of development engineers will support you, should you wish to use this technique for your application.
