1. In terms of the quality of the production, the core of the hot core box is difficult to guarantee in summer, while the cold core box also needs to pay attention to the air humidity, both of which have their own defects in the summer.
2. From the aspect of mold consumables, the cold core box is an absolute advantage, but compared with the hot core box, the only disadvantage is that the price of mold maintenance is much higher.
3. In terms of price, the resin and triethylamine used in cold box are more expensive. However, if the exhaust structure of the mold is adjusted, the dosage of triethylamine can be reduced, and it can be competitive.
4, the last point is about the labor environment, use in summer hot core box will produce larger taste, so in the summer, is a kind of test of workers, at the same time it proficiency requirement for workers is also high. And cold core box has bigger advantage in this respect, as long as the set environmental ventilation equipment properly, the new workers are very easy to use, fully use less than professional and technical personnel, the company will not worry because of the loss of personnel lead to slow production schedule.
