Application | Vortex flow sensor on mold temperature controller

Introduction

With the continuous development of industrial automation, precise temperature and flow control have become increasingly important in the production process. As a high-precision flow measurement device, the vortex flow sensor is widely used in various industrial settings.

The mold temperature controller, commonly used in the plastic and die-casting industries, improves product quality and production efficiency by controlling mold temperature. This article will explore the application of vortex flow sensors in mold temperature controllers.

Introduction to Mold Temperature Controllers

A mold temperature controller, also known as a mold temperature control unit, is an industrial device used to precisely control the temperature of a mold. It maintains the mold within a specific temperature range by heating or cooling the medium (such as water or oil). Its core components include a water tank, heating and cooling system, power transmission system, and valve control system. In the plastic industry, mold temperature controllers improve molding efficiency, reduce defect rates, enhance product appearance quality, and save energy. In the die-casting industry, they help reduce casting deformation and defects, prolonging mold life.

Application of Vortex Flow Sensors in Mold Temperature Controllers

The vortex flow sensor determines flow by measuring the frequency of vortices generated when fluid flows through a pipeline. It features a simple structure, no moving parts, high precision, wide range, and high reliability. It is widely used in industrial process control, energy management, and environmental monitoring.

Flow and Temperature Monitoring

In mold temperature controllers, precise flow control is crucial to ensuring uniform and stable mold temperature. The vortex flow sensor can monitor the flow and temperature of the medium in real-time and feed the data back to the control system. The control system adjusts the pump speed or valve opening based on this data to optimize the heating and cooling process, maintaining the set flow and temperature, thereby ensuring mold temperature stability.

If the sensor detects an abnormal flow, such as a sudden decrease or increase, it may indicate a blockage, leak, or pump failure in the system. Timely detection of these issues can prevent more severe equipment damage or production interruptions, improving system reliability.

Application Cases of Mold Temperature Controllers

Plastic Industry

In the plastic industry, mold temperature controllers help improve the efficiency and quality of the injection molding process. For example, precise mold temperature control significantly enhances product appearance quality and dimensional stability, reducing defect rates.

Die-casting Industry

In the die-casting industry, especially in the production of magnesium and aluminum alloys, using mold temperature controllers can significantly reduce casting defects. Controlling the flow of the cooling medium improves the surface quality of castings, reducing defects such as shrinkage cavities and heat bubbles.

Conclusion

The application of vortex flow sensors in mold temperature controllers significantly enhances the accuracy and reliability of the production process. Mold temperature controllers improve the efficiency of injection molding and die-casting processes, reduce defect rates, and extend mold life by precisely controlling mold temperature. Vortex flow sensors ensure stability and accuracy in the heating and cooling processes by monitoring the flow and temperature of the medium in real-time, indirectly improving product quality.
