Perspex Cutting and Fabricating Companies Can Produce A Myriad of Quality Products

Globally, the use of plastic products is at an all-time high. The reasons for this are quite easy to understand. It is easy to mould plastic into a wide range of products. Using plastic instead of other materials can be quite economical and affordable. In addition, advancements in technology have resulted in the emergence of different varieties of plastic that are strong and durable. Not many people realise the manifold ways in which they use plastic. Today, plastic has become an integral part of contemporary life. From plastic display stands to drinking bottles, plastic makes a major and irreplaceable contribution to everyday life. Its numerous traits make it suitable for use in nearly all products.

Many people would be surprised to know that there are over 45 different varieties of plastics. In addition, it is possible to use a number of methods for making each variety of plastic. Manufacturers of plastic products often vary the molecular factors of plastic to produce plastic with specific and desirable traits. For instance, by altering the molecular factor of a plastic, you could produce plastic that is more durable, transparent and flexible. Vacuum forming is one of the most essential processes used for manufacturing plastic. With it, you will be able to transform simple sheet of Perspex or acrylic into a desired product. But, if you want to create a prototype or a component from plastic, you will need to employ experienced plastic or acrylic fabricators.

For the uninitiated, acrylic denotes products containing a substance derived from acrylic acid or a related compound. In many cases, it refers to a material called Polymethyl Methacrylate (PMMA) or acrylic glass. Acrylic glass is a clear, glass-like plastic material. It possesses several useful features that make it a better alternative for many products that would otherwise comprise glass. Many people might be aware of the terms Plexiglas and Perspex. These terms denote premium-branded tradenames of acrylic. It is worth highlighting that there is no difference between acrylic and Perspex or Plexiglas. However, the companies producing Perspex manufacture it to the highest industry standards possible. Not surprisingly, Perspex has the reputation of being the best acrylic available.

Manufactured from methyl methacrylate monomer (MMA), Perspex comes in cast and extruded sheets. Perspex cutting companies in Sydney and other places cut these sheets and give them the desired form. Suppliers usually offer Perspex in a myriad of sheet sizes, cut-to-size panels, blocks, thicknesses, colours and textures. Perspex acrylic also comes in a diverse range of finishes as well. Perspex sheets in glossy, silky, matt, frosted, live edge and fluorescent finishes and textures are quite popular across the country. Perspex acrylic is highly versatile material. Thus, it is ideal for using in a diverse range of applications including signage, POS, visual communication, acoustics, design, architecture, furniture etc. Some organisations use it for window glazing, making kitchen & bathroom splashbacks and boat & car windows as well.

How Do Companies Produce Cast and Extruded Acrylic Sheets?

When you want to create a wide range of objects from acrylic, you will inevitably need the services of Plexiglas and Perspex cutting companies in Sydney and elsewhere. The process of acrylic fabrication enables workers to achieve a diverse range of effects. These workers will not need to use any specialised tools other than the ones that they currently use to produce these objects. Instead, they will simply need to vary certain aspects such as the shape, the levels of thickness and the complexity of the design.

Acrylic fabricators often work with two kinds of acrylic sheets. These comprise cast acrylic sheets and extruded acrylic sheets. To produce cast acrylic sheets, workers pump liquid Methyl Methacrylate (MMA) monomer into a mould made from two sheets of glass. Thereafter, they submerge the mould in warm water. This enables the process of polymerisation to take place. This process yields a sheet of rigid PMMA or acrylic.

In contrast, the process for manufacturing extruded acrylic sheets is more complex. Workers feed acrylic pellets from a containment silo to a feed hopper. The feed hopper usually lies above an extruder line. They feed the pellets into the extrusion barrel. A single or twin-screw auger system drives these pellets through the barrel. As the pellets move through the heated areas of the extruder barrel, the heat levels continue to increase. Eventually, the heat melts all the pellets into one molten mass.

 

The machine pushes this mass into a cone-shaped die, which widens out into the die lips. The pressure exerted by the screw drive makes the molten mass reach the die lips and push outwards to produce a molten sheet. It is worth mentioning that the height or gap of the die lips will be slightly larger than the thickness required for the finished sheet of extruded acrylic.

 

Lastly, the workers will pass the molten acrylic sheet through sets of cooling rollers. This process will typically produce extruded acrylic sheets having a standard gloss or smooth finish. But, if needed, the cooling rollers could end up embossing a pattern or finish other than the standard one onto the acrylic sheet as well. Unlike cast acrylic sheets, extruded acrylic sheets typically come in clear, opal and black colours. So, if you require coloured acrylic sheets, the plastic fabricators you employ in Sydney and elsewhere will invariably use cast acrylic sheets.

 

Make All Kinds of Products with Peerless Acrylic Design and Fabricating Services

Display stands and brochure holders are a common sight at trade shows and exhibitions. These objects serve to draw the attention of visitors to the stalls and booths that dot these exhibitions. Business owners often participate in these shows to increase the awareness levels of their brands. In their opinion, the more people they can reach out to, the greater the possibility of enhancing their sales. But, accomplishing this objective is not easy. For starters, you will need a booth that stands out from hundreds of others in the vicinity. Then, you will need to have sufficient signage and banners that can compel passers-by to pay a visit.

 

Not many people will be aware of it, but the plastic display stands that typically feature in trade shows, comprise acrylic. Acrylic or Poly Methyl Methacrylate (PMMA) came into being in the early 1930s. British chemists, Rowland Hill and John Crawford, were responsible for the discovery of this substance. The company that these chemists were working for, Imperial Chemical Industries (ICI), decided to register the product under the trademark Perspex.

 

At about the same time, Otto Röhm of Rohm and Haas AG in Germany was conducting experiments for producing safety glass. His experiment involved producing safety glass by polymerising methyl methacrylate between two layers of glass. The experiment was successful. The polymer separated from the glass in the form of a clear sheet of plastic. In 1933, Röhm gave this sheet of plastic the trademark name of Plexiglas. Over eight decades later, people continue to refer to acrylic by its more popular tradenames, i.e. Plexiglas or Perspex.

 

Acrylic did not take long to become an economical alternative to polycarbonates. It offered higher levels of tensile strength, transparency and ultraviolet-tolerance. In addition, it did not contain the harmful subunits of bisphenol-A that are present in polycarbonates. Not surprisingly, this transparent thermoplastic became a cost-effective alternative to glass. The fact that it was shatter-resistant and lightweight contributed to its popularity as well. In contemporary times, Perspex cutting companies in Sydney and other places use acrylic to produce a wide range of products.

 

Acrylic is increasingly becoming the material of choice for making residential and commercial aquariums. It comes into use in the lenses of exterior lights in automobiles too. Homeowners often purchase skylights, shower doors and bath enclosures made of acrylic. Many commercial establishments require components and products made of acrylic. For this, they turn to acrylic fabrication companies. Acrylic fabricators employ cutting-edge technology to achieve flawlessly crafted products for their clients. These professionals can offer cuts of high precision with minimal fuss. This makes them highly sought after, for designing and producing a wide range of components and products.
