冷芯盒制芯機(jī)也可以再原有熱芯盒射芯機(jī)上進(jìn)行改裝，只要增設(shè)一個(gè)吹氣裝置取代原有的加熱裝置。吹氣裝置主要是吹氣板和供氣系統(tǒng)。但供氣系統(tǒng)可以多機(jī)共用。此外，從環(huán)保角度來說，還要增加尾氣（即含有殘余SO2的氣體）凈化裝置。而且射芯機(jī)本身要加密封罩，可以局部密封，也可整機(jī)密封。

The cold box core making machine can also be retrofitted on the original hot box core shooting machine, provided that a blowing device is added to replace the original heating device. The blowing device is mainly the air blowing board and the gas supply system. But the gas supply system can be shared by multiple machines. In addition, from the environmental point of view, it is necessary to increase the exhaust gas (that is, the residual SO2 gas) purification device. Moreover, the core shooter itself must encrypt the seal cover, it can be partially sealed, or the whole machine can be sealed.
