Description

Press Forming Device {Press Forming Device}

The present invention relates to a press forming apparatus, and more particularly, to a press forming apparatus for taking out a product after cutting and removing unnecessary parts from an object manufactured in a soft plate shape.

In general, a protective member of various portable terminals or a case for protecting parts of each electronic device is protected by attaching or wrapping a protective material made of synthetic resin for insulation and shock absorption.

The original plate material is cut to fit the shape required for this, and press work is performed to manufacture it according to the shape and size.
