What you are talking about is the appearance of the mold, and the core inside should be customized according to the requirements of the product.

The appearance must be chamfered. The chamfering processing cost is low, and the chamfering milling machine can pass through it with one knife, and any milling cutter can chamfer, while the fillet needs to be processed with a fillet cutter, which is more expensive than ordinary milling cutters, so chamfering is easy and cheap.
