The self-hardening resin sand process is to add a certain amount of liquid resin binder and curing agent to the core and core sand at room temperature, so that it can self-harden the stroke in a core box or a sand box for a certain period of time. Core making process.
The Phenolic Coated Sand Reclamation Production Line has the following advantages:
1. High dimensional accuracy, low surface roughness and low casting rejection rate;
2. The type and core sand can be self-hardened at room temperature, energy saving and material saving, and improve working conditions of workers;
3, Type, core sand in the available time, good fluidity, under the effect of small tightness, better filling the complex shape and core parts, significantly reducing the labor intensity of workers;
4. The core sand has good collapsibility, and the castings fall sand and are easy to clean;
5. It can obviously increase the output per unit area of the workshop and reduce the dust content in the air in the workshop.
