The polymerization process can be initiated through several methods, including heat, radiation, or chemical reactions.
Extrusion or Casting
After polymerization, the acrylic resin is extruded or cast into the desired shape. Extrusion involves forcing the acrylic resin through a die, resulting in a continuous length of tubing with a consistent diameter. This process is commonly used for extruded acrylic tubing. Casting involves pouring liquid resin into a mold and allowing it to cure, resulting in solid tubing with a consistent diameter. This process is commonly used for cast acrylic tubing.
Cell casting, also known as cell cast acrylic or simply casting, is a manufacturing process used to produce acrylic sheets or blocks. It is a method that involves pouring liquid acrylic resin into a mold or between glass plates and allowing it to cure and solidify into a solid acrylic product.
After the tubing is formed, it undergoes a process called annealing. This involves heating the tubing to a specific temperature and then slowly cooling it down to relieve any internal stresses that may have occurred during the manufacturing process. Annealing helps to increase the strength and durability of acrylic tubing.
Cutting and Finishing
After annealing, the acrylic tubing is cut to the desired length and finished to the desired specifications. This can include polishing, drilling, and bending the tubing into various shapes.
In conclusion, acrylic tubing is made through a manufacturing process that involves several steps, including polymerization, extrusion or casting, cell casting, annealing, and cutting and finishing. In addition, large-diameter acrylic tubing is typically produced using cell casting. Understanding the manufacturing process of acrylic tubing can help you choose the right material and manufacturing technique for a specific project.
