1. Heating and cooling mixer SHR-500/1000L

• Function: This is equipment for the preparation of raw materials. It thoroughly mixes the various components (base polymer, dyes, additives, stabilizers) until a completely homogeneous mass is obtained. Heating helps melt ingredients and improve mixing, and cooling necessary to prevent sintering of the mixture and prepare it for loading into the extruder.

2. SJSZ80/156 conical twin screw extruder with loader

• Function: This "heart" the entire line. Here the melting and homogenization of the prepared mixture occurs.

  • Loader: Automatically feeds the bulk mixture from the mixer into the extruder, ensuring process continuity.

  • Two conical augers: As they rotate, they capture, compact, melt and mix the material. The conical shape of the screws creates the high pressure necessary for high-quality plasticization and extrusion of the melt.

  • Extruder: A homogeneous mass heated to the required temperature is squeezed out under high pressure through the following device - a die.

3. Mold (Die) (2mm-10mm)

• Function:This is a shaping tool. The molten polymer passes through its channel, acquiring a specific cross-sectional shape of the future product (sheet, pipe, profile, etc.).

• 4. Forming platform

  • Function: After exiting the die, the material is still soft and plastic. This platform (often with vacuum and/or cooling panels) provides precise calibration and fixation of the product's shape, preventing it from deforming until it has completely cooled.

  5. Three-roll calender

  • Function: Used primarily in the production of sheet materials. The rollers, rotating at different speeds, calibrate the exact thickness of the sheet, smooth its surface, remove possible defects and give the necessary smoothness or texture.

  6. Thermostat (Thermostat station)

  • Function: Provides precise temperature control at key process steps. It can heat or cool different areas of the line (eg die, calibration devices) to maintain optimal process conditions.

  7. Cooling bracket with trimming device

  • Function:

    • Cooling bracket: Finally cools the already formed product to a temperature at which it becomes hard and stable.

    • Trimming device: Trims uneven or deformed edges (flash) from a product, giving it its final precise geometric dimensions.

  8. Pulling device

  • Function: A very important element. It continuously and evenly grabs the cooled product and pulls it through the entire line. This creates a constant traction force that stabilizes the process and prevents deformation or accumulation of material during the extrusion stage.

  9. Cross cutting machine

  • Function: Automatically cuts a continuously moving product into segments of a strictly specified length. The cutter moves synchronously with the workpiece at the moment of cutting to ensure an even and clean cut without deformation.

  10. Stacker

  • Function: Final machine. He accepts the cut products and carefully, in piles or packs, places them on a pallet or in containers for subsequent packaging, storage and shipment.
