Acrylic Extruded Tube VS. Cast Tube
Q: Acrylic Cast Tube
At present, SMEACRYLIC extruded acrylic tube, which can produce a maximum outer diameter of 250mm, but if you need a larger size, you can consider Cast Tube, the outer diameter can reach 600mm, Thickness 10mm, The length is 1.0~1.2M. The manufacturing process is based on liquid MMA raw material, poured into the tube mold, and formed by the centrifugal principle. The dimensional tolerance is large, the process is long, and one piece can be produced. It is suitable for small-scale production. Better, because the molecular weight is high, it can withstand temperature of about 90 degrees, but there will be fine cloth wheel throw marks on the surface.

Q: Comparison table of Extruded Tube and Cast Tubes
  Acrylic Cast Tube Acrylic Extruded Tube
Manufacturing Operation

Using liquid MMA raw material, pour it into the tube mold, It is formed by centrifugal principle and has large dimensional tolerance. The production process is long, and one can also be produced, which is suitable for small-scale production. There will be slight cloth wheel throw marks on the surface.

Extruded from granular PMMA, with small dimensional tolerance, Fast production speed, suitable for mass production, It is normal to have small mold marks on the surface.
Tolerance Large  Small
Molecular Weight High (one million) Low (a hundred thousand)
Physical properties Good (The molecular weight is high, and the temperature resistance is about 90 degrees) Not Good (the temperature resistance is about 80°)
laser cutting OK OK
Polishing (cloth wheel) Good (Higher temperature resistance) Not very Good
Drilled (thick) Good (Good physical properties, high molecular weight) Need to drill slowly to avoid overheating (more likely to melt)
Production restrictions 1 pcs can also be produced Production base quantity required
