1、在使用铝板生产模具的时候，需要选择合适的加热温度。要严格控制挤压锭坯的合金成分。目前一般企业要求铸锭晶粒度达到一级标准，以增强塑性和减少各项异性。
1. When using the aluminum plate to produce the mold, it is necessary to choose the appropriate heating temperature. The alloy components of the extruded ingot must be strictly controlled. At present, the general enterprises require the grain size of ingot to reach the first grade standard, in order to enhance the plasticity and reduce the various heterosexual.
2、铝板生产模具上机前工作带必须经过研磨抛光，工作带一般要求抛光至镜面。对模具工作带的平面度和垂直度装配前要进行检查。
2. The front work belt of the aluminum sheet production die must be polished and polished, and the working belt is generally required to be polished to the mirror. Check for the flatness and perpendicularity of the die working belt before assembly.
3、铝板生产模具保温时间一般在2-3小时左右，但不能超过8小时，否则模具工作带氮化层硬度会降低而导致上机时不耐磨引起型材表面粗糙，严重的会引起划线等缺陷。

3, the aluminum plate production mold holding time is generally about 2-3 hours, but it can not exceed 8 hours, otherwise the mold working nitrided layer hardness will decrease, resulting in the machine wear-resisting, causing rough surface profile, and serious will cause the marking and other defects.
4、进行挤压生产前，需对型材截面进行充分计算，根据型材截面的复杂程度，壁厚大小以及挤压系数λ来确定挤压机吨位大小。
4, before extrusion production, we need to fully calculate the cross section of the section, and determine the tonnage size of the extruder according to the complexity of the section section, the thickness of the wall and the extrusion coefficient.
5、铝板生产模具卸模后，此时模具温度在500°C以上，如果立即浸入碱水中，由于碱水温度要比模具温度低得多，如果模具温度下降迅速，模具极易发生开裂现象。正确方法是等卸模后将模具在空气中放置到100°-150°C再浸入碱水中。
5, when the aluminum plate production mold is unloaded, the mold temperature will be above 500 degree C. If immersion in alkali water immediately, because the temperature of alkali water is much lower than that of the mold, if the mold temperature drops rapidly, the mold will easily crack. The correct method is to put the mold in the air to 100 -150 C and then immerse in the alkali water after the mold is unloaded.
