injection molding design
The principal method by which polymer or plastics material is converted into useful products is by moulding, usually under heat and pressure, in a hollow mould or die. The material takes the shape of the [...]
Manufacturing the Blow Mold-2
At some point in every design, it is essential for the eye to see and to comprehend the actual size of an object. For example, it is possible to represent, on a 12-in. CRT, the [...]
Manufacturing the Blow Mold-1
Manufacturing the Blow Mold While the hand duplicator or copy milling machine is still the backbone of the mold-making industry because of its ability to cut just about any shape with a high degree of [...]
Stretch Blow Process
The stretch-blow process is used to manufacture plastic containers which generally are lighter in weight and have greater clarity and improved physical Properties，compared to containers manufactured by other blow-molding Processes. In stretch-blow molding, the container [...]
Injection Blow Process
Injection-Blow Process The injection-blow process combines the function of blowing with the precision of injection molding; it requires a parison-forming mold with integral neck ring, multiple core rods (blow pins) and a blow mold. A [...]

neck insert-1
neck insert In most cases, inserted pieces are designed for the neck and base areas of the mold as noted previously. The neck insert cavity component is a replica of the finished product in the [...]
cost of plastic mold
Injection molds are made by a highly varied number of processes and combinations thereof. Figure 2.1 demonstrates the relative costs for cavities made from various materials. Accordingly, steel cavities appear to be many times more [...]
EDM,Wire Electrodischarge Machining and Cold Hobbing
Standard Electrodischarge Machining (EDM) This method is often called spark erosion and is widely used in the manufacture of cavities, cores and punches. EDM allows the generation of complex cavity and punch forms to be [...]
