Plastic parts are common in our lives, and many products are made up of a wide variety of plastic parts. Plastic parts can not be ignored as part of the following we briefly analyze the factors that affect the processing of plastic parts.
The loss of heat during the processing of plastic parts is an important aspect that must be considered. Usually, the loss of heat is caused by the uninterrupted transmission of plastic parts. In the injection molding production when the heat transfer are mainly three modes of radiation, convection and conduction, in addition to most of the mold is absorbed, but also part of the way by radiation, convection distributed to the air.
Plastic parts in the process of forming need to improve the utilization of heat, and cooling in the molding, you need to quickly reduce the temperature, the need to cool the mold on the battlefield, the cooling medium is usually used because of water price Low, the natural cost is low, the water after cooling can be recycled. But after all, everything has advantages and disadvantages, and the low prices and the options make it only as a primary coolant.
If you want to achieve the best cooling effect or the need for cold mode, where you need special reminder is not the cooler the cooler the better, the object is extremely anti-cold may be counter-productive. |
