1、砂芯常溫下在芯盒內(nèi)實(shí)現(xiàn)硬化，模具尺寸穩(wěn)定，砂芯尺寸精度高，形變小，從而可以降低鑄件尺寸偏差。
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，砂芯硬化速度以秒計(jì)算，遠(yuǎn)遠(yuǎn)高于殼芯和熱芯盒制芯工藝。
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、塑料和金屬材料制作，模具制造成本低、周期短，使用壽命長(zhǎng)。
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、由于常溫硬化，與熱法制芯比節(jié)省能耗，改善了工人勞動(dòng)條件。
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，砂芯潰散性好，鑄件清理費(fèi)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機(jī)設(shè)備，廣泛應(yīng)用于汽車、拖拉機(jī)、柴油機(jī)、內(nèi)燃機(jī)等行業(yè)鑄鐵件的生產(chǎn)。
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.
