Special cold water injection molding machine in the industry gradually becomes more and more widely used, its working principle is that we compare aspects of concern. The east star small make up to you in succession.

After heated to melt the plastic injection mold, condensation, after open mold ejection molding plastic parts, there are needed in the process of continuous production of mold cooling, shorten the plastic cement setting time, improve the dimensional precision of workpiece, forming quality and surface quality.

Frozen water temperature requirement: 6-18 ℃

Frozen water temperature requirements: plus or minus 2 K or + / - 0.5 K

Water chiller refrigeration capacity associated with injection molding machine injection quantity, injection amount is larger, the bigger the required refrigeration capacity.

Injection molding machine clamping force is often used to "tonnage" nominal, it needs to be "tonnage" into "oz", but "tonnage" and "oz" is not a one-to-one correspondence, the following is only on the control of the general situation of the transformation relationship, and there is a certain deviation.

extruded

Pipe extrusion, trough, cable and all kinds of plastic material.

Heat to melt the raw material after mold forming after a cold water bath after cooling, cold water temperature of water bath must remain the same.

Owing to the high production rate, thus needs large amount of cold unit.

If already frozen pond if enough, are not worthy to tank unit.

Bottle blowing

The main production of various kinds of mineral water bottles, soda bottles.

Compressed air drying - blowing bottles must be clean, dry compressed air, using industrial cold water machine with cold water as the cold source can remove the moisture in the compressed air.

Mold cooling - plating function of cold water control mold temperature accurately, improve product quality, improve production efficiency

Compressed air drying and mold cooling can use the same chiller as the cold source

With thermal LiSu

Plastic is heated under constant frequency die extrusion, so it is very important to maintain a constant temperature, the temperature range of chilled water demand is also very high, so we need a type of frozen water proportion valve from is to adjust the temperature accurately.
