520			_aManufacturers used plastic injection molding to produce a variety of affordable construction parts and products, such as hand tools, fasteners, and large and small accessories. However, plastic molding is usually done only on large machines. The study aims to develop a mechanized shredding, melting, molding machine for plastics to create a single-design cavity mold made from plastic materials. The prototype serves as a multipurpose machine where the worker just pours the right amount of the plastic materials into the feed hopper of the shredder and then powers it on. Then, let the machine do the work without exerting too much energy work then when the mold cooled down it can be taken out from the mold chamber to get the final product. Viable inputs were used to formulate the electrical diagram, process flow, and prototype assembly. The machine was fabricated using MS square tube 2” x 2” x 4 MMT and Stainless steel 304 Material which are the standard materials required in the development of the machine. Upon deployment, the machine was tested for its functionality and effectiveness. The shredding mechanism was tested for its shredding time per PET bottle with an average time of 4:52 minutes and for HDPE bottles with an average time of 9:59 minutes. The melting mechanism was also tested for 3 different sample trials per plastic type. The average output value of temperature controller 1 is 167°C and the average output value of temperature controller 2 is 175°C for PET plastics. For HDPE plastics, the average output value of temperature controller 1 is 184°C, and the average output value of temperature controller 2 is 200°C. The prototype was evaluated by 35 respondents in Incorporation and Universities and was rated 4.6, with a very good descriptive rating. The prototype was functional, but it only partially solves the issue of plastic waste because the molten plastic can easily be cooled down. After all, the nozzle doesn't have a heater band wrapped directly around it. The control panel also requires rewiring and the setting up of a trip wire to ensure that the output values of temperature controllers 1 and 2 do not exceed their input values.
