PVC hot/cold Mixer Unit

A hot/cold PVC mixer unit is a specialized piece of equipment used in the processing of PVC (polyvinyl chloride) compounds, particularly in the production of PVC-based products such as pipes, fittings, profiles, and more. This unit combines the functions of mixing and cooling or heating the PVC materials to achieve the desired properties and characteristics for further processing.


  • A hot/cold PVC mixer unit typically consists of a mixing chamber, heating and/or cooling elements, a motor and drive system, temperature control devices, and discharge outlets.
  • The mixing chamber is designed to accommodate PVC resin, additives, and other components, allowing for thorough blending and homogenization of the materials.
  • Some units are equipped with heating elements to elevate the temperature of the PVC compound, while others have cooling systems to lower the temperature as needed.
  • Temperature control devices, such as thermocouples and sensors, monitor and regulate the heating or cooling process to maintain the optimal temperature for the PVC mixing operation.

  • Mixing: The PVC mixer unit functions to mix PVC resin with various additives and compounding ingredients, such as plasticizers, stabilizers, lubricants, and fillers. This step ensures that the PVC compound achieves the desired properties, such as flexibility, impact resistance, weatherability, and color uniformity.
  • Heating or Cooling: Depending on the specific requirements of the PVC formulation and processing, the unit can raise the temperature of the PVC compound to facilitate the blending of ingredients or lower the temperature to prevent premature fusion or degradation of the materials.
  • Homogenization: The mixer unit promotes the thorough blending and homogenization of the PVC compound, ensuring that all components are uniformly distributed throughout the mixture, leading to consistent product quality.
  • Discharge: Once the mixing, heating, or cooling process is completed, the PVC compound is discharged from the mixer unit for further processing, such as extrusion, molding, or pelletizing for the production of PVC products.


  • Hot/cold PVC mixer units are widely used in the manufacturing of PVC-based products, including pipes, fittings, profiles, cables, films, and various construction materials.
  • These units are essential for compounding PVC formulations with specific properties and performance characteristics tailored to different end-use applications.
  • The precise control of mixing, heating, and cooling processes in the PVC mixer unit ensures the production of high-quality PVC compounds with consistent properties and performance attributes.

In summary, a hot/cold PVC mixer unit plays a critical role in the PVC processing industry by effectively blending, heating, or cooling PVC compounds to achieve the desired formulation for the production of a wide range of PVC products.
