How much does a mold temperature controller cost?

Here is everything you need to know about a mold temperature controller.

The mold temperature controller price will be big different for different types. LCEQ mainly have two types, water-type and oil-type according to their different heating medium. The temperature range of water ones can generally be within 180 degrees Celsius. If the needed temperature is higher than 180 degrees Celsius, we recommend using an oil temperature controller. The temperature range of the oil-type can be within 350 degrees Celsius.

From the aspect of temperature control range, we can divide them into ordinary type and high temperature type. The temperature range of the ordinary water-type is generally within 120 degrees Celsius. It can reach 180 degrees Celsius for those of high temperature ones. The temperature range of the ordinary oil-type is within 200 degrees Celsius. And it can reach 350 ℃ for those high temperature ones.

What combination of structure in mold temperature controller is it to complete the temperature control? In fact, if the mold temperature controller wants to reach the set temperature and maintain the constant temperature state, multiple systems will cooperate with each other. There is an electronic control system, mechanical system, liquid level monitoring system, heating system, cooling system, temperature sensing system, pressure relief safety system etc. Each system has different functions. So how do they work? Please continue to go through.

Working Principle

Working principle of mold temperature controller

How does the various systems in the mold temperature controller work?

Let’s take a water-type mold temperature controller as an example.

The mechanical system (circulation pump) delivers the water and heat produced by the heating system to the mold so as to heat up and keep the mold temperature.

There is a liquid level monitoring system sensing the water level. When the water level is too low, it will notify the electronic control system, and the latter will notify the pressure pump to replenish water. On the contrary, when there is too much liquid, it will stop refilling.

The temperature sensing system is responsible for measuring the temperature. After set the temperature we want to heat, the temperature sensing system will transmit the measured data to the electronic control system. If the temperature is lower than set temperature, the electronic control system will notify the heating system start heating. When the temperature reaches the set temperature, the heating system stops heating. When the temperature is higher than the temperature we set, the electronic control system informs the cooling system to work.

LCEQ machine’s cooling system adopts plate heat exchange in the continuous work through indirect cooling method. As we all know, the water will become vapor at a certain temperature and there will be pressure generated in the closed system. According to this principle of thermal expansion and contraction, when the pressure is too high, the pressure relief system will exhaust and relieve pressure to ensure the safety of the mold temperature controller.

The electronic control system will issue commands to the corresponding system to do corresponding work at critical moments according to the data provided by each system so that the continuous cooperation work can keep the temperature constant.

Selection Guide

How to select the mold temperature controller?

According to the size of the mold and the required temperature, mold temperature controllers with different powers can be selected. After selected the right model and heating power, we can quote the mold temperature controller price to you.

Heater power KW=W×▲t×C ×S/860×T

W=mold weight (KG)

▲t=The temperature difference between the required temperature and the starting temperature

C=specific heat, oil 0.5, steel 0.11, water 1, plastic 0.45~0.55

S=Safety factor 1.5~2, a small value can be selected for single machine

T = heating time to the required temperature H

Application

Application of Mold Temperature Control Unit

What role does it play?

With the progress and development of society, the products on the market has increased and become various. The technological requirements have also been continuously improved. In a modern factory, it is necessary to reduce manpower, improve production efficiency, and reduce the cost of the operation strategy of the factory. The mold temperature controller can quickly raise and lower the temperature, and quickly reach the required temperature of the product. Therefore, the use of the mold temperature control unit can improve product quality and production efficiency.

Mold temperature controllers are also commonly used in plastic molding processing such as plastic injection molding process, extrusion process, injection blowing process, calendering process production and so on. However, it is also critical to choose a mold temperature controller with stable and durable temperature control. Of course, in addition to plastic molding processing, the mold temperature controller is also useful for the production of diapers and sanitary napkins. As long as the process requires heating and constant temperature, it can be realized by the mold temperature control unit. The following briefly introduces the role played by the mold temperature controller in the plastic molding process.

Application in extrusion process

The mold temperature control device controls the temperature accurately and stably, which can eliminate the cold wire from entering the high temperature die head. When the die is in contact with the plastic, there will be a temperature difference. The mold temperature controller can prevent the fluctuation of the extrusion pressure caused by the fluctuation of the plastic temperature. To ensure the stability of the extrusion volume, so as to ensure the quality of the extruded product, it can completely remove the moisture and oil on the surface of the product, and avoid the possibility of pores in the product.

The mold temperature controller is used to control the extrusion mold, always maintain our set working temperature to ensure the stability of product quality. It also can optimize the processing time.
