Key Explanation
Deep drawing is a forming process where pressure is applied to a sheet material to create a seamless, three-dimensional shape. This method is ideal for applications requiring airtightness and high strength.

Creating a necked section in the middle of the product presents a high level of difficulty.

Progressive deep drawing is well-suited for small, high-precision products. However, successful execution relies on experience and know-how that cannot be fully quantified.
