1.High production efficiency: The working process of the hot core box core shooting machine is completed at the same time of sand filling and compaction, and is immediately hardened in the hot core box, and the cycle time can be only ten seconds to several tens of seconds. Produce a sand core for casting.
2. The quality of the sand core is good: it can shoot sand core of any complexity, and the size is accurate and the surface is smooth, which can reduce the machining allowance of the casting.
3. It can save a lot of auxiliary equipment and tools for core making, such as core furnace, dryer, core bone, wax line and so on. The coated sand process saves a lot of work procedures than the wax line, and the coated sand is sanded with different castings.
