Internal gas pressure process
The internal gas pressure process enables the production of high-quality molded parts with cavities without sink marks. The gas is pressed into the interior of the melt as holding pressure during cooling, so that a cavity is formed. This results in low-warpage, stable components with low weights.
- Less weight
- Reduction of cooling time
- High rigidity
- Low warpage
Wherever cavities in injection-molded parts are so complex that they can no longer be demolded conventionally, the fusible core technology offers itself as a problem solver. With complex inner contours, such as B. Impellers with flow-optimized blades, we use multi-part melt cores that are inductively melted out after manufacture.
Examples of the procedural steps for manufacturing articles with cavities:
