1. Upgrading of heating method: Replace the traditional integral heating tube with partitioned independent temperature-controlled heating plates, and divide 3-5 temperature control areas according to the different heating requirements of the plastic mold (such as edge and center areas). Each area is equipped with independent thermocouple sensors and PID temperature controller, the temperature control accuracy is improved from ±5℃ to ±1℃, avoiding material deformation caused by local overheating or incomplete forming caused by overcooling.
2. Energy-saving transformation: Install nano insulation cotton + reflective film on the outside of the heating plate to reduce heat loss; at the same time, add an "intermittent heating trigger mechanism". When the material temperature reaches the set value, the heating power is automatically reduced to 30% for insulation, which is compared with traditional heating methods. Energy saving by 25%-30%.
