In order to enable the foundry to better use the furan resin sand self-hardening sand process and overcome the inconvenience in use, Shandong Yongchuang Casting Materials Co., Ltd. specially developed the A+B curing agent automatic control instrument, which can automatically adjust and constantly release the mold. The smart device of time. Its characteristics are as follows:

1. Keep demoulding time constant

Within the range of sand temperature 0-60℃, it can ensure that the demolding time does not change with the temperature and remains at a certain value.

2. The curing speed can be flexibly set

 According to the specific situation, the curing speed can be set to a certain value:

Curing speed 1…………………………10 minutes demoulding

Curing speed 2…………………………20 minutes demoulding

Curing speed 3…………………………30 minutes demoulding

Curing speed 4……………………40 minutes demoulding

3. Only two curing agents required

Only high acidity value curing agent A and low acidity value curing agent B are needed throughout the year, which is convenient for production management.

4. Save the amount of curing agent

The amount of curing agent is 30-40%, which reduces consumption by about 20%, reduces sulfur increase in castings, and improves casting quality.

5. Optimize resin sand process

Maintain the best ratio of curing agent, give full play to the effectiveness of resin, improve core quality, reduce casting waste, and increase economic benefits.
