The temperature differences during the production of the head.


The head needs temperature support during manufacture. Due to the different materials used to make the head, the temperature requirements are also different. The following describes the temperature differences during the production of the head.

The head manufacturing unit determines whether the protection of the surface high temperature is required according to the situation. If necessary, a margin should be left to remove the oxide layer on the surface of the head. According to the type, specification and material of the head, the whole head or the panel can be formed by cold stamping, hot stamping, cold spinning, hot spinning, cold rolling, hot rolling, etc. Then group welding into a head. The atmosphere in the heating furnace is neutral or weakly oxidizing. The heated flame should not be in direct contact with the workpiece. When the aluminum head is formed, the head manufacturing unit determines whether the protection of the surface high temperature is required according to the situation. If necessary, a margin should be left to remove the oxide layer on the surface of the head. The heating temperature should generally not exceed 420 degrees. When the temperature of the part drops below 300 degrees, it is not suitable to continue hot forming.

Titanium heads should be thermoformed as much as possible, such as the molding temperature is about 300 degrees-400 degrees. During high temperature thermoforming, the workpiece heating temperature can be increased to about 650 degrees, but should not exceed 800 degrees. After cold forming, the heat-setting temperature is 100-350 degrees. When the hot forming temperature is above 600 degrees, the working surface should use high temperature resistant coatings or other protective measures to prevent surface oxidation pollution; when the hot forming temperature is 500-600 degrees, the head manufacturing unit determines whether the surface high temperature is required according to the situation Protection. If necessary, a margin should be left to remove the oxide layer on the surface of the head.
