40HP Water Cooled Screw Chiller Mold Cooling Injection Molding Blister Molding Blow Molding

Product Description:

The water chiller plays a vital role in the cooling process of the injection molding machine mold. The following is a detailed explanation of how the water chiller cools the injection molding machine mold:

1. The role of chillers:

Injection molding machine chillers are mainly used to cool down the molds of injection molding machines. During the injection molding process, the mold and plastic melt need to be cooled quickly and stably to avoid product deformation, shrinkage or other quality problems. The chiller produces chilled water to discharge the heat generated by the mold in time, thereby ensuring the surface finish and dimensional accuracy of the plastic product.

2. Types of Chillers:

Chillers are mainly divided into two types: air-cooled and water-cooled:

• Air-cooled chiller: The heat generated by the condenser is dissipated into the air through a fan, and no additional cooling water system is required, which is easy to install. However, the heat dissipation efficiency is relatively low, and it is suitable for occasions with low ambient temperature or limited space.

• Water-cooled chiller: The heat is taken away by water circulation, and the heat dissipation efficiency is high, but an external cooling water system, such as a cooling water tower or well water, is required.

3. Selection principles of chillers:

• Power matching: The power of the chiller must meet the needs of the injection molding machine. The injection molding machine usually indicates its power requirements. When selecting a chiller, you should ensure that its power is greater than or equal to the required power of the injection molding machine to ensure that the chiller can provide sufficient cooling capacity. At the same time, you also need to consider the cooling capacity of the chiller (usually in tons of cooling) to ensure that it can cover the cooling needs of the injection molding machine at maximum load.

• Temperature control: The cooling water temperature range of the injection molding machine is generally between 6 and 18 ° C. The cooling water temperature difference should be controlled within ±2K or ±0.5K to ensure accurate control of the mold temperature.

• Water flow demand: During operation, the injection molding machine requires a certain amount of cooling water to maintain the temperature of the mold and melt. Therefore, when choosing a chiller, you also need to consider whether its cooling capacity can meet the water flow demand of the injection molding machine.

During the injection molding process, plastic pellets are heated and melted before being injected into the mold. After solidification, the mold is opened and ejected to form the plastic workpiece. The chiller continuously absorbs the heat of the mold through circulating cooling water and takes it away, thus ensuring that the temperature of the mold is always kept within an appropriate range. This helps to shorten the plastic solidification time and improve the workpiece dimensional accuracy, molding quality and surface quality.

Production Features:

Water-cooled screw chiller has the following characteristics:

1. High refrigeration efficiency: The water-cooled screw chiller uses a screw compressor, which has the advantages of high efficiency, low noise, low vibration, and good stability. It can quickly cool down and meet large-scale refrigeration needs.

2. Large refrigerating capacity: The water-cooled screw chiller has a large refrigerating capacity and is suitable for places requiring a large amount of cooling, such as large buildings and industrial manufacturing enterprises.

3. Good stability: The key components such as the compressor, condenser and evaporator of the water-cooled screw chiller are made of high-quality materials, with high durability and stability, and can run stably for a long time.

4. Simple maintenance: The maintenance of the water-cooled screw chiller is relatively simple. It only needs basic maintenance such as regular cleaning, inspection and filter replacement to maintain its normal operation.

5. Environmental protection and energy saving: The water-cooled screw chiller uses environmentally friendly refrigerants and has a high energy efficiency ratio. At the same time, it can realize energy saving and environmental protection benefits through linkage control with other systems.

6. Strong adaptability: The water-cooled screw chiller can be combined in various forms according to the needs to meet the refrigeration requirements of different occasions and different needs. It is a highly flexible refrigeration equipment.

Working Principle:

The working principle of the water-cooled screw chiller mainly includes four processes of compression, condensation, expansion and evaporation.

• Compression process: Under the action of the screw compressor, the refrigerant is compressed into a high-temperature and high-pressure gas, while absorbing the surrounding heat.

• Condensation process: High-temperature and high-pressure refrigerant enters the condenser, and through contact with cold water or surrounding air, it emits heat and cools into a high-pressure liquid.

• Expansion process: The high-pressure liquid refrigerant enters the evaporator through the throttle valve, the pressure drops suddenly, and the liquid refrigerant expands into a low-pressure refrigerant while absorbing the surrounding heat.

• Evaporation process: The low-pressure refrigerant enters the evaporator, absorbs surrounding heat through contact with water or air, turns into a low-temperature and low-pressure refrigerant, and returns to the compression process.

Through such a cycle process, the water-cooled screw chiller can deliver cold water to the area that needs to be cooled to achieve the effects of cooling, dehumidification and keeping the air fresh. At the same time, the water-cooled screw chiller will also emit a certain amount of heat, which needs to be dissipated through cooling towers or other heat dissipation equipment to ensure the normal operation of the system.
