冷芯盒制芯机也可以再原有热芯盒射芯机上进行改装，只要增设一个吹气装置取代原有的加热装置。吹气装置主要是吹气板和供气系统。但供气系统可以多机共用。此外，从环保角度来说，还要增加尾气（即含有残余SO2的气体）净化装置。而且射芯机本身要加密封罩，可以局部密封，也可整机密封。

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.
