Aumax AMTC Series Mold Temperature Controller Application

Aumax AMTC Series Mold Temperature Controller Application

1. Aumax Mold Temperature Controller adopts P.I.D. temperature control system, so it can provide a stable mold temperature under any working situation. A stable mold temperature is very important to injection molding production. Aumax AMTC mold temperature controller can achieve accuracy ±1℃, provide a great reliability of thermal balance to injection mold.

2. Aumax mold temperature controllers are mainly used to heat the injection mold and keep the temperature stable. It can save the injection cycle time and ensure a high quality of plastic injection parts. Mold temperature affects surface quality, fluidity, shrinkage, injection cycle and deformation. The high or insufficient temperature of the mold will have different effects on different materials. For thermoplastic material, a higher mold temperature usually improves the surface quality and fluidity, but prolongs the cooling time and injection period. The lower mold temperature will reduce the shrinkage in the mold, but it will increase the shrinkage of the injection molded parts. For thermosetting plastics, a little higher mold temperature will usually reduce the cycle time, and cycle time determined by injection parts cooling time. Additionally, in plastic molding industry, a higher mold temperature can reduce plastisizing time and number of cycles.

3. Mould, AMTC mold temperature controller and heat transfer fluid is the three necessary factors to control mold temperature. In order to provide heat to mold or remove heat from mold, all parts of the system must meet the following conditions: A. Inside mold, the surface area of cooling channel must be large enough, runner diameter should match with pump power and pressure. The cavity temperature affects injection molded parts, so a suitable mold temperature reduce mold inside pressure, improve injection molded parts quality, reduce injection circle time and save production cost. B. Mould temperature controller must keep the heat transfer fluid temperature accuracy at 1℃－3℃ according to the injection molded parts quality. Aumax AMTC series mold temperature controller can achieve accuracy between ±1℃, therefore, it can fully meet the mentioned production request. C. The heat transfer fluid must have good heat conduction ability, it must import or export large heat within a short time. Base on thermodynamics, water is obviously better than oil.

4. Aumax mold temperature controller operational principle: The machine consists of water tank, heating system, cooling system, power transmission system, level control system, temperature sensor, charge sprue, etc. Normally, the water pump is power transmission system, it transfer the hot or cool liquid from tank to mold, and then back to tank form mold. Temperature sensor measures the fluid temperature and send signal to control system. Control system adjusts liquid temperature directly and adjusts mold temperature indirectly. During production, if mold temperature is higher than setting value, the control system will open solenoid valve and import cooling water until mold temperature reduce to setting value; if mold temperature is lower than setting value, control system will turn on heating elements and import hot water to mould.

5. Aumax AMTC Series mould temperature controllers have 2 types, including water type mold temperature controller and oil type mold temperature controller. Water type mold temperature controller can achieve mould temperature 120℃, while oil temperature controller can achieve mould temperature 200℃.  

6. For oil type mold temperature controller: A. keep machine away from fire. B. Use tapered leakproof pipe connector, temperature resistance and pressure resistance soft or hard pipe. C. Check leakage of connector and mould regularly, check function of control system and temperature sensor regularly. D. Use Synthetic oil which with good thermal stability and low coking tendency. Change oil regularly.

7. Water also can be used as heat transfer liquid; it is more economical, clean and easy operation. If any part leaked, water can be discharged into sewer directly. However, it is also disadvantageous to use water as heat transfer fluid: water is with low boiling point; because of corrosion and scaling, different water increase pressure loss and reduce heat exchange efficiency inside mold. For water type mold temperature controller: A. Pretreatment with corrosion inhibitor to the temperature control loop (pipe s

How Does Honeycomb Dehumidifier Work?

Honeycomb Dehumidifier is also called wheel dehumidifier. Dehumidifiers can be divided into two categories: civilian dehumidifiers and industrial dehumidifiers. Usually, conventional dehumidifiers are composed of compressors, heat exchangers, fans, water containers, housings and controllers. Its working principle is: The fan draws the moist air into the machine and passes through the heat exchanger. At this moment, the water molecules in the air condense into water droplets, and the treated dry air is discharged out of the machine. Such circulation keeps the indoor humidity at an appropriate level. Relative humidity.

The core structure of the dehumidification unit is a continuously rotating honeycomb dryer wheel. The runner is the most critical part of the moisture absorption in the dehumidifier. Its medium is made of several special titanated fibers, and it is composited with a small amount of ceramics and subjected to high temperature treatment. The carrier composed of such media can not only greatly limit the moisture absorbent, but also has a high strength, and can be better applied to various complicated working environments. The cellular structure design greatly increases the surface area where the moist air and the moisture absorbent interact with each other, thereby greatly improving the working efficiency of the dehumidifier.

How Does Hopper Dryer Works?

The hopper dryer is a new generation product of standard hot air dryers. The environmental protection factors have been fully taken into account and improved on the basis of the original functions. It can dry raw materials that are wetted by packaging, shipping or recycling.

In raw material processing, the hopper dryer blows a constant high-temperature wind into the drying drum through the drying fan. After the raw materials are baked, the original moisture of the raw materials in the barrel is taken away to achieve the purpose of removing moisture contained in the raw materials. The wind blown by the blower becomes a high-temperature dry hot air after being heated by electric heating. Through the screen protector and the perforated screen, the hot wind energy is uniformly dispersed in the raw material of the dry barrel air drying drum. Optional hot air recovery device, the blow out of the wind after the return air filter into the drying fan to form a closed loop circuit, saving electricity.

How Does Cooled Water Chiller Work?

Cool Water Chiller is divided into two types: Air-cooled Water Chiller and Water-cooled Water Chiller. Chillers are divided into low-temperature chiller and normal-temperature chiller for temperature control. Normal temperature is controlled within the range of 0-35 degrees. Inside. Low temperature machine temperature control is generally in the range of 0 degrees - minus 45 degrees.

When a chiller refrigerant is cycled, the liquid refrigerant in the evaporator absorbs heat in the water and begins to evaporate. A certain temperature difference is formed between the final refrigerant and the water. The liquid refrigerant also completely evaporates into a gaseous state and is inhaled by the compressor. In compression, the gaseous refrigerant absorbs heat through the condenser and condenses into a liquid. After the throttling of the thermal expansion valve, the refrigerant turns into a low-temperature and low-pressure refrigerant and enters the evaporator, completing the refrigerant cycle.
