The cooling system is extremely important to the economics and operation of the designed mold , and yet remains one of the most under engineered systems in injection molds. Perhaps the reason for the lack of engineering is that the temperature distribution is not obvious when molding compared to defects related to flow.Improperly designed cooling systems often result in two undesirable outcomes. F...

Another example of insert molding is provided in Figure 13.7[53],which is particularly directed to the control and improvement of weld lines around an inserted component for the production of a water faucet handle.The mold design consist of two separable mold halves 30and 31 having recesses 32and 33 that together form a mold cavity. The inserted component 35 is held in position by two opposing ...

Injection mouldingcan be performed with a host of materials mainly including metals, (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed, and forced into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is de...
