What is an injection molding oil temperature machine?
As the name suggests, an injection molding oil temperature machine is an injection molding oil temperature machine that uses heat transfer oil as a heat transfer medium. It can also be called an oil heater, oil temperature heater, or oil circulation temperature controller.
principle
Injection molding oil temperature machineThere is a storage tank on its own, and during operation, the heat transfer oil enters the system from the storage tank and is pumped into the mold or other temperature controlled equipment through a circulation pump. After coming out of the temperature controlled equipment, the heat transfer oil returns to the system, repeating the process. The heat transfer oil is heated by the heater, and when the medium temperature detected by the temperature sensing probe reaches the set value, the heater stops working. When the temperature is below the set value, the heater starts working, and when the temperature reaches the set value, it stops working again. This cycle repeats itself!

role
The injection molding oil temperature machine, as a commonly used auxiliary equipment in injection molding production, should not be underestimated in its role and function. The injection molding oil temperature machine is suitable for assisting in the production of engineering plastics and plastic products. The injection molding oil temperature machine is first pre adjusted to reach the temperature required for the injection mold, producing high-quality products in one molding process and reducing the need for trial molding materials. Mold temperature machine accurately reduces waste, provides production and quality, and is an indispensable tool in the injection molding industry.
1. Shorten the molding cycle and improve production efficiency;
The first function of an injection molding oil temperature machine is to shorten the molding cycle, mainly by shortening the cooling and solidification time of the plastic parts through the oil temperature machine.
2. Improve the dimensional accuracy of injection molded parts
The injection molding oil temperature machine is used to adjust the thermal balance of the mold, reduce the shrinkage rate of the injection molded parts, and minimize the deformation of the plastic parts caused by internal stress. Thereby improving the dimensional accuracy of plastic parts.
3. Improve the appearance quality of injection molded parts
The injection molding oil temperature machine improves the surface quality of plastic parts by stabilizing the mold temperature. During the injection filling process, the hot melt must maintain good fluidity. If the temperature of the injection mold is too high or too low, it will affect the molding quality. The injection molding oil temperature function can achieve a good thermal equilibrium state of the mold temperature, which is beneficial for reducing injection molding defects.
4. Preheat in advance, heat the mold
The temperature range of the injection molding oil temperature machine is from room temperature to 350 ℃, and the mold temperature can be preheated or heated in advance by heating.

model selection

Many people do not know how much heating power or pump size they need when choosing an injection molding oil temperature machine. Generally, only the required temperature and heating time are known. Then the manufacturer will calculate and select the appropriate oil temperature machine power.
The general heating temperature is determined by selecting the type of oil temperature machine, standard (180 ℃) or high temperature (300 ℃). The higher the heating power of the oil temperature machine, the shorter the required heating time, thereby reducing the initial heating time. However, a larger heating power is not necessarily better, and the cost of the unit will also be higher if the heating power is too large.
When calculating and selecting the heating power of an injection molding oil temperature machine, attention should be paid to the following three aspects:
1. Starting power of injection molding oil temperature machine
2. Power during operation
3ohdHeat loss in the system
In addition, when calculating and selecting the heating power of the injection molding oil temperature machine, extreme environmental conditions should also be considered, such as extremely low ambient temperatures, extremely short operating cycles, * * high operating temperatures, and the * * heavy weight of the heating medium (the flowing medium is * * high flow rate).
Steps for calculating and selecting the heating power of injection molding oil temperature machine:
1. Draw a process flowchart for heating and temperature control based on the production process (without involving material form and specifications).
2. Calculate the heat required for the manufacturing process.
3. Calculate the amount of heat and time required for system startup.
Normally, we can calculate according to the following formula: KW=W × △ t × C/860 × T
W=Weight of heated medium or hourly increase in medium (KG)
△ t=difference between medium control temperature and initial temperature
C=specific heat of the medium: oil (0.7-0.8), steel (0.11), plastic (0.45-0.55), water (1.0)
T=Time required to heat the medium to the desired temperature (in hours)

It should be noted that the initial heating power and the maintenance heating power after the equipment reaches the set temperature are different and need to be calculated separately. However, when determining the total heating power after * *, the maximum value should be chosen and an appropriate safety factor should be selected to ensure that the heating power of the injection molding oil temperature machine meets the user's needs.
