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.

More advantages:
  • Less weight
  • Reduction of cooling time
  • High rigidity
  • Low warpage

Core-melting process

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:
