Works with liquid or solid thermoset resin as the binder for core sand mixture into heated core box, sand core in hot core boxes soon hardened to a certain thickness (about 5~10 mm) be removed, the surface smooth, precise size high quality core product. Hot core box shell core machines compared with conventional core shooting machine has the following advantages: 1 high production efficiency: hot core box shell core machines working processes are sand and firm at the same time for completion, and hardening in hot core box immediately, a cycle of just more than 10 seconds to dozens of seconds, will be produced for the purpose of casting cores. 2 cores are of good quality: the shooting of any complexity cores, and precise dimensions, smooth surface, which can reduce machining allowances. 3 service equipment can save you a lot of cores and tools, such as core ovens, dryers, rodding, wax lines. 4 reduce the labor intensity, flexible operation portable, easy to learn, uses electric heating, temperature control, easy to keep clean, creating conditions for the mechanization and automation of core processes. 5 If the matching gas generating system, this machine can meet the requirements of cold box core.
