A motorbike helmet is a good example - the outside of the helmet is smooth because of the mould it was made in. Using acrylic as an example: a cut that is close to the line will be made with a saw of choice, a file can be used to remove more acrylic, so the profile is closer to the line, is then used to remove the file marks from the acrylic, known as ‘rubbing down’, once the file marks are removed, a fine abrasive paper can be used to achieve a, finish is required, then an electric buffer or car body polish can transform the matt finish to a glossy one, It is possible to add a personalised pattern to a polymer using a, , which can look like a regular inkjet printer but has, a sublimation printer is used to print onto coated, heat-resistant paper, the paper is then placed on top of the polymer and heated, using a heat press, to around 180 to 200°C, the paper can be removed from the polymer, transferring the image from the paper to the polymer, Common polymers to which sublimation patterns are added are. Backed by the Government, it has … The main thermosetting plastics are epoxy resin, melamine formaldehyde, polyester resin and urea formaldehyde.
