Most hollow blow molding machine injection molds are designed with several separate cooling zones. The neck and bottom require the most heat to be discharged, and cooling is challenging and important in the injection mold design of the blow molding machine. The drilling cooling pipe is installed where it is most needed. For better production control. The most effective cooling is therefore required.
The die cavity is usually machine cut. Copper alloy injection mold also has high heat transfer and good corrosion resistance. However, the material required for making the injection mold must have high thermal conductivity and sufficient cutting edge strength. The current aluminum 7075 makes most of the advanced alloys used in injection moulds.
Because of the good machinability of the metal. Its high cost, high price, and because of its three times the proportion of aluminum, may be more serious wear on the molding machine. It is easy to be repaired by welding or inlaying by injection mould made of steel alloy.
Because the strength and hardness of the cast aluminum can not meet the requirements of the cutting edge. The thermal conductivity of the cast aluminum injection mold is worse than that of the cutting aluminum injection mold. The die cavity usually needs to be broken into copper alloy or stainless steel inlays.
The operating holes and shoulders are inlaid with copper alloy or stainless steel. The bottom and neck are also inlaid with these two metals. Casting injection molds can also be made of copper alloys by casting. The cast steel mold cavity is relatively easy, and the Kirk alloy (zinc) casting can be made on the steel mold. The die cavity and the bottom plate are cast into a determined size. Because of the lack of strength of the Kirk alloy to cut the plastic. Because it relies on pressure or gravity casting. These cavities have many fine components made of steel mold or ceramic injection mold. The above technology is provided by Huangyan Taizhou Wei Wei Machinery factory. Www.kautas.com
