What are the wet bag process and the dry bag process?

The CIP molding process is divided into two methods: the wet bag process and the dry bag process.

Wet bag process:

In this method, the powder material is placed in a flexible mold bag and placed in a pressure vessel filled with high-pressure liquid. This process is ideal for producing multi-shaped products and is suitable for small to large quantities, including large-sized parts.
