What is cooling of injection molds for auto parts?
In everyone’s impression, a car is composed of sheet metal, engine, bearings and other accessories, which you may ignore. Some accessories are made of plastic materials. For example, the steering wheel, armrests, and airbag external devices of the car are all made of plastic. Become.
So how are these plastic products made? Most of the automotive plastic parts are molded by the cooling and demolding of the injection molding machine. This is to use a special mold chiller to cool the mold of the injection molding machine.
Due to the different characteristics and shapes of various automotive plastic parts, it is required to maintain an appropriate cooling rate. Therefore, the mold must be equipped with heating and cooling systems according to the molding requirements to maintain a certain mold temperature. When the material temperature increases the mold temperature, it should be cooled. Use a special mold chiller to prevent the plastic parts from deforming after demolding, shorten the molding cycle, and reduce the crystallinity.
There are air-cooled chillers and water-cooled chillers for molds. The air-cooled box type does not need to be connected to a cooling water tower. It is easy to install and suitable for open places. The water-cooled box-type chiller needs to be connected to a cooling tower and a water pump. The cooling effect is better than that of the air-cooled type, and it is suitable for placing in the workshop.
What is the price of a mold-specific chiller? It depends on how much cooling capacity and power to choose? The greater the power, the higher the cost, and the smaller the cooling capacity, the cheaper the unit price. This must be matched according to the actual use of the customer. If you are looking for a Jiusheng chiller manufacturer, the wholesale price directly will be much more favorable than the middleman.
How long is the warranty period of the mold-specific chiller?
Generally, the manufacturer's warranty period for the production of chillers is one year. Of course, the warranty period can also be extended by adding a price, mainly depending on the needs of customers.
Dongguan Jiusheng Machinery Co., Ltd. specializes in the production of air-cooled chillers, Water-cooled Chillers, Open Chillers, Screw Chillers, Air-cooled Box Chillers, Water-cooled Box Chillers, etc.
