Injection Molding Special Water-Cooled Chiller

Product Introduction

Injection molding special water-cooled chiller, water circulation industrial refrigeration unit for the plastics and rubber industries: used for cooling plastic processing machinery and molding molds, it greatly improves the surface smoothness of plastic products, reduces surface marks and internal stress, prevents product shrinkage and deformation, facilitates demolding, accelerates product setting, thereby significantly enhancing the production efficiency of plastic molding machines.

Detailed Introduction

I. Classification of Injection Molding Special Water-Cooled Chillers:
First, we need to distinguish the types of chillers: generally, chillers are divided into water-cooled and air-cooled types.
Air-cooled chillers: equipped with cooling fans, no cooling tower required. Easy to install and move. However, they have high environmental requirements; since they rely on heat dissipation for cooling, poor ventilation in the installation workshop can directly affect the chiller's cooling performance.

Water-cooled chillers: require installation of a cooling tower for heat dissipation.

III. Role of Injection Molding Special Water-Cooled Chillers in Plastic Machinery:

1. Chillers used for cooling plastic processing machinery and molding molds can greatly improve the surface smoothness of plastic products, reduce surface marks and internal stress, prevent product shrinkage and deformation, facilitate demolding, accelerate product setting, thereby significantly enhancing the production efficiency of plastic molding machines;

2. Chillers used for CNC machine tools, jig boring machines, grinders, machining centers, modular machines, and various precision machine tools for spindle lubrication and hydraulic system transmission medium cooling can precisely control oil temperature, effectively reduce machine tool thermal deformation, and improve machining accuracy.

Injection Molding Special Water-Cooled Chillers Used in Various Industries

Chillers for the plastics and rubber industries:

Cooling plastic processing machinery and molding molds can greatly improve the surface smoothness of plastic products, reduce surface marks and internal stress, prevent product shrinkage and deformation, facilitate demolding, accelerate product setting, thereby significantly enhancing the production efficiency of plastic molding machines.

Chillers for extrusion lines and pelletizing industries:

Clearly, the water tank is an open container, so when selecting a chiller, note that the evaporator should be shell-and-tube type, not coil type. Reasons: coil-type chiller evaporators are open tanks; when the chiller stops, the pump has no pressure, and the water level in the tank is usually higher than the chiller, causing water to flow back into the chiller's tank and overflow. Shell-and-tube types are different, with a closed-loop evaporator, avoiding overflow issues.

Chillers for CNC machine tools, jig boring machines, grinders, machining centers, modular machines, and various precision machine tools: used for spindle lubrication and hydraulic system transmission medium cooling, precisely controlling oil temperature, effectively reducing machine tool thermal deformation, improving machining accuracy, enhancing mechanical lubrication efficiency, reducing wear, and extending machinery life.

Chillers for the electronics industry and ultrasonic cleaning industry:

Stabilizing the molecular structure of electronic components on production lines through cooling, improving component pass rates, lowering cleaning agent temperature, condensing gaseous cleaning agents, effectively preventing volatilization.

Chillers for vacuum ion coating industry:

Ion sources require heating for startup and cooling during operation; cooling system failure can damage the ion source. Cooling water must be pumped at high pressure through cooling channels in the ion source.

Chillers for the electroplating industry:

Cooling electroplating solutions to stabilize metal and non-metal molecules. Chillers enable rapid, stable current adhesion of metal molecules to plated surfaces, increasing density and smoothness, shortening plating cycles, improving quality, and effectively recycling various expensive chemicals. Similarly applicable to vacuum coating industry.

A. Direct cooling: The plating solution directly passes through a filter or filter screen into the chiller's evaporator for cooling before returning to the plating tank. Advantages: short cooling time, effective cooling; disadvantages: evaporator requires anti-corrosion treatment (usually titanium alloy), prone to scaling, needs regular cleaning to avoid affecting cooling performance and machine operation.

B. Indirect cooling: Titanium tubes are installed in the plating tank; chilled water passes through the tubes to absorb heat from the plating solution. If titanium tubes are impractical, a heat exchanger (titanium alloy) can be added, with chilled water on one side and plating solution on the other.

Chillers for the food industry:

Used for rapid cooling of various heated foods to meet canning and bott requirements. Also, various fermented foods require different cooling temperatures to stabilize fermentation, improve product quality, and ensure fermentation standards. Similarly used in pharmaceutical and chemical industries.

Injection Molding Special Water-Cooled Chiller:

During the grinding process of three-roll mills, temperature rises due to molecular structure changes, affecting raw material quality, production efficiency, and causing severe equipment wear. Using chillers for circulatory cooling controls temperature, greatly increasing production and reducing equipment damage.
