1、砂芯常温下在芯盒内实现硬化，模具尺寸稳定，砂芯尺寸精度高，形变小，从而可以降低铸件尺寸偏差。
1. The core hardens in the core box at room temperature. The mold size is stable, the core size precision is high, the deformation is small, so the casting size deviation can be reduced.
2、制芯效率高，砂芯硬化速度以秒计算，远远高于壳芯和热芯盒制芯工艺。
2, the core making efficiency is high, and the hardening rate of sand core is calculated in seconds, which is much higher than that of shell core and hot core box making process.
3、模具可以用木材、塑料和金属材料制作，模具制造成本低、周期短，使用寿命长。
3. The mold can be made of wood, plastic and metal materials. The mold has the advantages of low cost, short cycle and long service life.
4、由于常温硬化，与热法制芯比节省能耗，改善了工人劳动条件。
4. Because of hardening at room temperature, the ratio of heat to core saves energy and improves workers' working conditions.
5、除水玻璃CO2法外，砂芯溃散性好，铸件清理费用低。
5, the CO2 method of removing water glass has good collapsibility of sand core and low cleaning cost.
利用三乙胺法值得的射芯机设备，广泛应用于汽车、拖拉机、柴油机、内燃机等行业铸铁件的生产。
The core ejector equipment worth using triethylamine method is widely used in the production of iron castings in automobile, tractor, diesel engine, internal combustion engine and other industries.
