Compression mould usually use hydraulic press machine and the cavity and core is fixed to top and bottom platens of machine. Once the material is placed into the open mould, the machine closes, mould get heated, then the press pressure force material to flow all over the mould.
Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. to obtain the desired products.
Mold selection is a very important part of the entire mold making process.
The requirements for mold design and production are: accurate size, smooth surface; reasonable structure, high production efficiency, easy to automate; easy to manufacture, high life, low cost; design meets process needs, economical and reasonable.
Design is the key step in the production of molds, the initial step of production, and controls the whole process of mold production. Therefore, the design also has a great impact on the service life of the mold. The design mainly affects the service life of the stamping mold from the following two aspects.
Because different molding dies have been applied in many fields, and the manufacturing technology of professional dies has also undergone certain changes and developments in these years, in this part, the general design rules of vacuum blistering dies are summarized.
