A number of people have some misconceptions pertaining to acrylic. In their view, acrylic will turn yellow, become brittle or crack with the passage of time. However, none of these concerns are correct. These issues might arise with some cheaper varieties of plastic. But, no acrylic product will ever develop or manifest these issues. This is why plastic fabricators in Sydney and other places consider acrylic to be their material of choice. Its versatility makes it suitable for use in a wide range of applications. In addition, if taken care of properly, acrylic will continue to look as good as new for years to come. Even age or prolonged exposure to the elements will not make it fade or crack. However, it is worth highlighting that extruded acrylic is not as strong as cell cast acrylic. As such, it could crack or splinter during the machining process. This is one of the reasons that plastic fabricators prefer using cell cast acrylic for making higher quality products.
One of the best qualities of acrylic lies in its ability to acquire almost any shape and form with minimal fuss. Fabricating companies typically use an array of moulds and cutting instruments to give acrylic the desired form and shape. When workers cut acrylic sheets, they will usually need to ascertain the kinds of cuts that they will need to make. For this, planning is invaluable. Many acrylic fabricators use table routers for cutting acrylic sheets. Not only is this method highly versatile. It also produces edges of superior quality.
Circular saws and table saws are ideal for producing straight cuts. Similarly, band saws or scroll saws are ideal for performing short and curvy cuts. For accurate straight line cutting, setting up a fence can be worthwhile. Some fabricators employ fine-toothed blades such as plywood panelling blades that fit their saws perfectly. Some saws provide workers with the options needed for controlling the speed. It goes without saying that while fabricating acrylic, the slower the speed, the better the results will be.
Working with glass or metals can be tough. Both materials can be quite heavy. So, manoeuvring them to make the appropriate cuts can be taxing. Similarly, glass is not as tough as acrylic is. In contrast, metals are much stronger than glass. But, cutting metals is not as simple or easy as cutting acrylic. Cutting metals requires additional amounts of effort. This is why many fabricating companies prefer working with acrylic. To produce acrylic in the desired form or shape, fabricators will first cut the acrylic sheet with a saw or with CNC flatbed routers. They will bend the acrylic into the desired shape with heat benders. These benders comprise heated elements that soften the plastic in a seam. Thereafter, workers would be able to bend the acrylic into the desired shape on a jig or another similar tool.
On occasions, the workers could place the acrylic over a purpose-made mould and put it in a specially made oven. Doing so would enable the acrylic to drape over the mould and form a new shape. Known as drape moulding, this process is quite popular among many plastic fabricating companies. Once the plastic has cooled down and bent or formed into its new shape, workers will glue it into place using an assortment of gluing methods. To makes the edges look attractive, workers will use diamond polishers or flame polishers. The former uses heads comprising real diamonds for buffing, sanding and polishing the acrylic, thereby giving it a perfect, glass-like edge. The latter polishes the joins with jets of extreme heat. Vacuum forming and blow moulding are other processes that plastic fabricators typically use. These processes make it easier to create acrylic domes and spheres.
