1、 Core components of the production line

1. Extruder host
   • Screw and barrelMelting and plasticizing plastic particles through heating and shear force (key parameters: aspect ratio, screw design).
   • drive systemDriven by traditional motors or servo motors, the screw speed is controlled to regulate the extrusion volume.
   • Heating and cooling systemSegmented temperature control to ensure uniform plasticization; The machine head needs to be cooled to prevent material burning.
2. Mold (head)
   • Design TypeCustomized according to the cross-section of the profile, such as using a splitter shuttle design for different profiles, and using spiral pipes.
   • materialHigh resistance running in steel or tungsten carbide coating, extending service life.
3. Cooling and shaping system
   • Vacuum shaping tableThrough water mist spraying and negative pressure adsorption, quickly cool and fix the shape of the profile (especially suitable for PVC).
   • Immersion cooling tankSuitable for crystalline materials such as PE and PP, controlling crystallinity.
4. Traction and cutting device
   • Tracked tractorMultiple sets of track clamping profiles, synchronized driving to ensure straightness.
   • Automatic cutting machinePlanetary cutting or flying saw design, precise cutting according to the set length.
5. auxiliary system

   • Feeding MachineAutomatic feeding reduces manual contact with high-temperature materials.

   • Crushing and recycling deviceProcessing waste materials to achieve circular production.

2、 Workflow

1. Preparation of raw materialsPre mixed colorants, fillers, and other additives are accurately measured using a weight loss scale or volume scale.

2. Plasticizing extrusionThe screw rotates to push the material forward, and it is melted and homogenized through the heating section.

3. Forming coolingMolten plastic is formed through molds and immediately enters the solidification stage for solidification.

4. Traction shapingThe traction machine pulls the profile at synchronous speed to eliminate internal stress.

5. Cutting and stackingAfter cutting according to the set length, it is automatically stacked by the conveyor belt.
