The coated sand was invented by Dr Cronin in the second world war. The process is to mix the powdery thermosetting phenolic resin with the original sand machine and solidify when heated.Develop with thermoplastic phenolic resin after latent curing agent (methenamine) and lubricant through a mixture of precoated sand coated process, when the heat of precoated sand coated on the surface of the sand, resin melt, in methenamine decomposition of methylene, under the action of molten resin by linear structure rapidly into molten body structure, so that the curing of precoated sand.
CNC SLS SLA Vacumm casting tooling
The mixing method of mulching sand has gone through four stages of dry mixing, cold covering, warm coating and hot film.The thermal process is to heat the raw sand to a certain temperature, and then mix it with the resin, the water solution of ullode and the calcium stearate, which is cooled and broken and sieved.Because of the difference of formula, the mixing process is different.The current domestic many different kinds of coated sand production line, manual feeding of about 2000 ~ 2000 semi-automatic production lines, computer control automatic production line already has nearly 50, effectively improve the production efficiency and product stability.Such as benevolence and casting co., LTD. Beijing automated visual line, control the charging time, accurate to 0.1 second heating temperature control precision to 1/10 ℃, and it can through the video always observe sand state, the production efficiency of 6 tons/hour.
