The core insert is a key component used in the production of transparent packaging shells. The material for the plastic parts is Eastar EN058 PET natural. Each mold consists of four cavities, and each cavity is formed using a core insert. This design allows for more convenient modifications. Instead of moving the entire mold, only the specific core insert that requires adjustment can be removed and replaced.
One of the standout features of this product is the high precision required for the plastic surface polishing. The polished surface must achieve a mirror-like finish, as seen in the image, where the plastic surface reflects light just like a mirror.
