How to understand the Cooling System Design ?

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. First, cooling and cycle times are much longer than what could have been achieved.If you need help, pls contact me, i am Phoebe, my email is injectionmold2004@163.com  whatsapp +86 182 3716 2307 

How to control Insert Mold with wall Temperature

   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 pins 36. After mold closure and prior to mold filling, asubstabtially uniform cavity thickness exists between the inserted component 35 and the mold halves 30and 31.In this mold design, the mold wall temperture of the mold is locally controlled by the flow of a controlled fluid through channels 40 and 42.Different fluids such as water,oil,or steam can be provided to different portions of the mold at different temperatures.

injection molding

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 designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers which do not melt during the injection moulding of some lower temperature thermoplastics, can be used for some simple injection moulds.Parts to be injection moulded must be very carefully designed to facilitate the moulding process; the material used for the part, the desired shape and features of the part, the material of the mould, and the properties of the moulding machine must all be taken into account. The versatility of injection moulding is facilitated by this breadth of design considerations and possibilities.Do you want to know more?hello,i am Cherry,pls contact me by eamil:injectionmold2008@163.com                      by whatsapp:+86 15112289056
