Problems solved by technology

The traditional mold temperature machine uses heating rods to heat, and when the oil temperature machine uses heating rods to heat, it will generate high temperature and cause carbon deposition, just like scale, which will affect the heating efficiency of the heating rods. If they are not cleaned after a long time of use, the heating efficiency will be affected. And it may cause damage to the mold temperature machine, but after the mold temperature machine is disassembled, it is difficult to clean and the sealing is complicated, resulting in longer downtime and greater losses

In the traditional heating rod type mold temperature controller, the temperature around the heating rod can reach about 600°, which will cause the heat transfer oil to decompose and form carbon deposition phenomenon covering the heating rod, which greatly affects the heating efficiency and the maintenance cost of the mold temperature controller.
