Some people say that the mold cavity and core are the heart of the mold, because they are the key components that directly form the shape of the product, and their accuracy, surface quality, structural design, etc. directly affect the dimensional accuracy and appearance of the product. Others think that the screw of the injection molding machine is the core, which plays a key role in the plastic conveying, plasticizing and injection process, and is crucial to the plastic melting quality, injection volume control and molding cycle. What do you think?
