Mold Temperature Controller

Precise temperature control (core function): Accurately control the temperature of key parts such as the extruder barrel, die head, and screen changer at the process set value (accuracy can reach ± 1 ℃ or even ± 0.1 ℃), ensuring that the material plasticizes and flows within the optimal temperature range.

Preheating and startup acceleration: Uniformly preheat the extruder before starting up, greatly reducing the waiting time for heating and avoiding equipment thermal stress damage caused by rapid heating.

Process cooling and thermal balance: When the extrusion process exceeds the temperature limit due to screw shear heat, the mold temperature machine can automatically switch to cooling mode, and take away excess heat through a heat exchanger to achieve a dynamic balance of "heating cooling" and ensure constant temperature during the extrusion process.

Improve yield and quality: Accurate and stable temperature control can make material plasticization more uniform, extrusion pressure more stable, thereby increasing extrusion yield and significantly improving the color, mechanical properties, and dimensional stability of the final particles.

4、 Core structure composition

Heating system:

Heater: Made of flanged stainless steel electric heating tube, equipped with imported heating wire (such as imported from Sweden), filled with magnesium oxide powder to ensure uniform heating, long service life, and no local overheating.

Power design: Double or multiple heating power designs are commonly used, which can automatically switch according to actual loads and have significant energy-saving effects.

Circulating pump:

Adopting high-temperature eddy current circulation pumps (such as Taiwan Yuanxin, Germany SPECK and other brands), it is resistant to high temperatures, leak free, runs smoothly, and ensures stable medium flow and pressure.

Cooling system:

Plate heat exchanger (indirect cooling): mainstream design, high heat transfer efficiency, compact structure, no direct contact between heat transfer medium and cooling water, ensuring the purity of the medium.

Cooling solenoid valve/proportional valve: precise control of cooling water flow to achieve smooth cooling.

Temperature control and electrical system:

Pipeline system:

Adopting stainless steel integrated molding pipeline (304), reducing pipe resistance and rust scale, with low heat loss and uniform heating.

Equipped with accessories such as expansion tank, exhaust valve, pressure gauge, flow switch, etc.
