Applications of Industrial Chillers in the Plastics and Rubber Industry

Industrial chillers are key equipment in the plastics and rubber industry, ensuring continuous production, improving product quality, and reducing energy consumption. Their core application is mold cooling, which significantly shortens the molding cycle. Below is a summary of specific applications and core values shared by Jianlong Hydraulic Technology based on different process stages:

1. Applications in the Plastics and Rubber Industry

1.1 Application Area 1: Injection Molding

· Specific Process Stage: Mold Cooling

· Core Function and Value: (Core Application) Removes heat from the mold, allowing molten plastic to cool and solidify rapidly. Shortens the molding cycle by approximately 60%-70%, improving production efficiency; prevents product shrinkage and deformation, ensuring dimensional accuracy and surface finish.

1.2 Application Area 2: Extrusion Molding

· Specific Process Stage: Shaping and Cooling

· Core Function and Value: Rapidly cools and shapes pipes, profiles, cables, etc., preventing deformation due to gravity. Ensures accurate product dimensions and increases production line speed.

1.3 Application Area 3: Blow Molding

• Specific Process Steps: Mold Cooling & Air Path Drying

• Core Role and Value: Dual Role

。Cooling the mold ensures a uniform and full bottle body with consistent wall thickness.

。Cooling compressed air removes moisture, providing a dry air source and ensuring clean preforms.

1.4 Application Area 4: Rubber Compounding

• Specific Process Steps: Internal Mixer/Open Mill Temperature Control

• Core Role and Value: Removes the enormous heat generated by friction between the rubber and the rotor, preventing the rubber from scorching or breaking down molecular chains due to high temperatures. Ensures stable rubber compound performance and extends equipment life.

1.5 Application Area 5: Auxiliary Equipment

• Specific Process Steps: Hydraulic System Cooling

• Core Role and Value: Cools the hydraulic station oil temperature (usually <60℃), maintaining oil viscosity. Ensures stable power transmission, prevents aging and leakage of seals, and reduces wear on hydraulic components.

2. Key Considerations in the Process

2.1 Multi-loop and High-precision Temperature Control: Rubber mixing processes require temperature control accuracy of ±1°C to prevent material degradation. Some thermoforming processes (such as yogurt cup production) are extremely sensitive to temperature differences and require proportional valves to precisely control chilled water flow.

2.2 Water Quality Management and Filtration: Plastic processing often generates dust and debris, which can easily clog equipment pipelines. Therefore, chiller systems are usually used in conjunction with filtration devices to ensure clean water and guarantee long-term stable equipment operation.

2.3 Cooling Capacity Matching: The cooling capacity of the equipment must be directly linked to the production line's capacity (such as the ounce count of an injection molding machine or the clamping force in tons). Scientific calculations are needed to ensure that the temperature remains controllable even under high-load production.
