冷芯盒造型是把混砂机(P1)混制好的湿态树脂砂加入冷芯盒射芯机(P1)内，再用压缩空气把砂子吹入模具型腔，并通过三乙胺发生器(P1)将三乙胺气体吹入模具，使砂型快速固化。三乙胺法混砂用粘结剂一组分为酚醛树脂，二组分为聚异氰酸酯，催化剂为三乙胺。

该机型模板尺寸较大，将射砂机构和吹气机构设计为横向移动，可使取芯和更换模具获得更加开阔的空间。

Thesize of the model template is large, and the sａnd shooting mechanism and the air blowing mechanism are designed to be laterally moved, so that the core can be replaced and the mold can be replaced to obtain more open space.
