(2) see if the sand is serious. Sand design is usually unreasonable, which will increase the consumption of coated sand, and the cost is high.

（3）了解制芯循环时间长短，同等条件下，时间越短证明加热棒分布越合理，效率也会更高。

(3) understand the length of the core cycle. Under the same conditions, the shorter the time is, the more reasonable the distribution of heating rods will be and the higher the efficiency will be.

（4）现在大家对后期的服务也是非常的看重的！看厂家是否提供售后服务与技术支持。

(4) now we are also very concerned about the late service. See whether manufacturers provide after-sales service and technical support.

（5）设备的成品率的高低是最重要的，不要选择废品率较高的机器。
