It is very common to have uneven temperature points when casting wire drawing dies, so how can we better ensure uniform production at various temperatures?
Controlling fluid temperature is the most common way, and the control accuracy can meet the needs of most situations. If you use this control method, the temperature displayed on the controller is not consistent with the mold temperature; the mold temperature fluctuates very sharply, because the thermal factors affecting the mold have not been directly measured and compensated for these factors, including the change of the injection cycle, the injection speed, Melting temperature and room temperature. Then there is the direct control of the mold temperature. This method is to install a temperature sensor inside the mold, which is only used when the mold temperature control accuracy is relatively high.
The main features of mold temperature control include: the temperature set by the controller is consistent with the mold temperature; the thermal factors affecting the mold can be directly measured and compensated. Under normal circumstances, the stability of the mold temperature is better than by controlling the fluid temperature. In addition, the mold temperature control has better repeatability during the production process. The third is joint control. Joint control is a combination of the above methods, it can control the temperature of the fluid and the drawing die at the same time.
