The study aims to produce plaque using recycling materials. The plaque is manufactured using Compression Moulding (Hot Pressing). The mould design was employed by a computer-aided and fabricated using a CNC milling machine. Three different types of plastic resins were investigated: Poly-ethylene Terephthalate (PET), High-Density Polyethylene (HDPE), and Poly-propylene (PP). The quality of the semi-finished product was examined using Differential Scanning Calorimetry (DSC) and Thermal Gravimetric Analysis (TGA) techniques. The test profiled the outcome in thermal behaviour graphs to represent its behaviours. As a result, the recycling Polyethylene Terephthalate (PET) quality is unsuitable for producing plaque due to its brittle characteristics that introduce crack defects to the final product. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
