The numerical control processing of the mould of the blow molding machine is typical and has higher requirements than the numerical control processing of ordinary products.
In the processing of molds, all kinds of CNC machining are used. The most widely used are CNC milling and machining centers. CNC wire cutting and CNC EDM are also widely used in mold CNC machining.
Wire cutting is mainly used in various Kind of straight-wall mold processing, such as concave and convex molds in stamping, inserts, sliders in blow molds, electrodes blow molding machine at https://www.dianyamold.com/ for EDM, etc.
For mold parts with high hardness, machining methods cannot be used, and most of them use EDM. In addition, EDM is also used for sharp corners, deep cavity parts, and narrow grooves of the mold cavity.
The CNC lathe is mainly used to process standard parts of mold rods, as well as mold cavities or cores of rotating bodies, such as blow molds for bottle bodies and basins, and forging molds for shafts and disc parts.
In mold processing, the application of CNC drilling machines can also improve processing accuracy and shorten the processing cycle.
