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 mould, from which it is then removed. The relationship between the final product and its mould is of critical importance,…

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 material is biaxially ented by stretching and blowing the parisons at a critical temperature, which is different for each of…

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 core rod is moved into the parison mold and material is injected into the mold to form a Precision parison…
