Firstly the machine in 3D software will be designed and then based on the calculated load that the machine will be subjected to, the analysis will be done and the material of the machine will be decided. Further this the fabrication of the machine will be done on the basis of the analysis done. In this machine, shredded plastic is put through the hopper into heating chamber. Inside the heating chamber, plastic is heated up to its melting temperature and then by lever arrangement which followed by press to final fabrication of the tiles. It will be beneficiary to the society and the small scale industrialists as the products made from it will be available at a cheaper cost. Fabrication of the machine so that the waste plastic can be recycled at a much cheaper cost with the use of more economical and compact injection- molding machine. Key Words: Plastic Recycling Machine, Injection Molding Machine, molding machine, waste recycling machine, plastic, landfill avoidance. 1. INTRODUCTION Waste plastic has become a huge problem for the world and disposal of it presents numerous challenges in front of us. Out of the huge amount of waste plastic generated only 9.1% of the plastic is recycled, rest all is just thrown away in ocean posing problems to the marine life. The paper deals with the recycling of the waste plastic and converting it to some useful products such as tiles, beams, decorative products by the use of more economical and less power consuming machine which is better than conventional machines available in market thus reducing the cost of the products manufactured. It involves the collecting, sorting, shredding and melting of the plastic and thus producing the products using the different types of the products. 1.1 Collecting The actual collection of plastic can happen in a number of ways depending on the cultural and economic context of your country as well as the partners you decide to work with. Some examples are, collection from the surrounding area, from local shops or manufacturers, local waste pickers or from the local waste stream. 1.2 Sorting Sorting is done manually by checking the SPI code. Once the unsorted plastic comes in the workspace you should separate it in the relevant sorting bags (labelled with appropriate SPI code). Check each product for the small code (it can be numbers or letters in the triangular recycling sign), this is usually very small and can be difficult to find. Usually, it is embossed in the plastic itself at the bottom/inside of the product or printed on the label. Once you spot what plastic type the product is you can drop it in the appropriate sorting bag with the same SPI code. 1.3 Shredding In this stage, the sorted plastic is shredded using the shredder machine. The size of the machine may vary from purpose to purpose, depending on the amount of the plastic to be shredded. The size of the granules or the shredded plastic depends on the sleeve that is used in the shredder. 1.4 Washing Plastic needs to be clean before undergoing recycling processes. Dust, dirt and impurities will cause problems to Plastic machines and processes. Dirty plastic can result in extra maintenance, breakdowns, problematic productions and low-quality products. 1.5 Storing The washed plastic is stored in the different labeled containers so that it can be easily identified and used when needed. 2. MECHANISM USED It uses the lever and the plunger arrangement to transfer the force applied by the human on the lever to the plunger via the connecting rod that connects the lever and the plunger. 3. WORKING PRINCIPLE The working principle of the injection-molding machine is similar to the syringe used for injection. It uses the thrust of the plunger to inject the melted plastic into the closed cavity,
