How Is Extruded Acrylic Made?

Each type of acrylic is manufactured using different processes, and with the case of extruded acrylic, the manufacturing process involved is extrusion. With this particular process, manufacturers make use of extrusion grade polymers, which is different from the kind of polymer used in making cast acrylic. One difference between these two kinds of polymers is their molecular weight, where the former (extrusion grade polymer) has lower molecular weight than the latter (cast grade polymer).
The extrusion process starts by feeding the extrusion grade polymers or resin pellets into an extruder. This equipment then heats the resin pellets until they melt and become molten mass. The molten mass is then forced out of the extruder’s barrel and into steel dies where are flattened to form large extruded acrylic sheets. The thickness of the acrylic sheet is determined by the space between the steel dies – the larger the space, the thicker the resulting acrylic sheet will be. The acrylic sheet is then fed into cooling rolls, after which they move to the cutting process where are they cut into smaller pieces, packaged and sent to the markets for selling.

If you want to have a specific measurement cut from an extruded acrylic, you can try to contact the manufacturing company and inquire if they can accommodate your requests. Unfortunately, while many manufacturing companies do accept such job orders, they will only do so if the order is large enough. If you can’t get a manufacturing company to manufacture the size of the extruded acrylic that you want, you can always rely on plastic fabricators or acrylic laser cutting in Sydney to cut them into the right size for you.

Extrusion is a preferred method for manufacturing acrylics mainly because of its many advantages over other methods. For one, this process is more economical as there are lesser amounts of waste products resulting from it. This is one of the primary reasons why sellers are able to sell extruded acrylic at much lower prices. Extrusion is also faster and more flexible than other methods, and it allows for close tolerances especially when it comes to the acrylic’s thickness.
