AB curing agent intelligent controller

(1) Keep the demoulding time constant: within the sand temperature 0-60 ℃, to achieve a constant mold release. Reduce head and tail sand.

(2) The curing speed and the amount of addition are automatically adjusted according to the sand temperature and weather temperature .

(3) Only high and low acidity sulfonic acid curing agent are needed throughout the year, which is convenient for production management.

(4) Optimize the resin sand process: maintain the best ratio of curing agent, give full play to the effectiveness of the resin, reduce the amount of addition, improve the quality of the core, reduce casting waste, and increase economic benefits.

(5) The addition amount of resin and curing agent ,the flow rate of sand realize the screen display more intuitively.

(6) Realize one-click conversion of resin addition amount of molding sand backing sand and surface sand, easy to operate, economical and practical, reduce resin addition amount.
