- 4. Plastic waste is one of the greatest source of waste which has been increasing since the plastic was first used as a daily need product. But, most danger property of plastic is that is does not degrade with time which makes it difficult to dispose. A good quality of plastic is that it can be Recycled or Reused. We can reuse some of the products, like plastic bottles, Chairs, etc, (We are using thermoplastic polymers for molding) Plastic recycling is the process through which we can use these plastic to create new products. Plastic Injection Molding Process is one of the most used manufacturing process. So, we decided to make a plastic recycling machine that can reuse scrap plastic to make useful product and at a cheaper cost.
- 5. In our project we are going to carry out recycling using Injection process. Injection molding machine is a mechanically operated mechanism in which the shredded plastic is heated to change its state from solid to semi liquid and then injecting (pushing) it into a die, that has an cavity of shape of our final product. This machine is made at least possible cost and is capable enough to start a business from home and commercialize it. Products formed can also be made into combination of colors. Injection machine is flexible enough to create different product just by changing the die.

- 9. P r o c e s s Injection molding process can be performed in following four Steps :- Step-1: DIE CLOSING The process starts with Closing the die and clamping the die to vice. Step-2: HEATING AND INJECTING The heated Plastic is injected into a Mould Cavity. Step-3: COOLING Once the mould cavity is filled, the part is allowed to Cool. Step-4: EJECTION After cooling, the final product is taken out from the mold.

- 12. Plastic Injection Molding Process is one of the most used manufacturing process capable of producing flexible and economical parts at a large scale. Evaluate current industry processing standards and determine what practices are beneficial and sustainable. Demonstrate a recognition of alternate methods of injection molding. Recognize commonly used terminology and componentry utilized in injection molding. Determine how properly manage, prepare and cool plastic materials throughout the injection molding process. Analyze the phases of the injection molding process and determine the appropriate machine setting are for each phase Evaluate if an injection mold is a good match for an injection molding machine.

Thus, the calculation of probable cost of project is as follows :
- 14. Labour cost is low. It is easy in construction. Fast production & Low waste. Material and color flexibility. It can be operated by even an unskilled person. It can be developed further to make it more efficient and make it automatic. To this mechanism there is low maintenance. Any required shapes and sizes are can be required with the help of the die. This also helps to clean up our surrounding and help in recycling and reusing the already used plastic.
- 15. Accuracy is comparatively less. High initial cost if automation is done. Limited size objects only can be created. Accurate costing may difficult.
- 16. These are useful for recycling thermoplastics by suitable product. Small objects can be manufactured. Mechanical part can be made. Injection machine is cheap enough to build at home. Simple jobs can be made according to die. Using this machine many useful products can be manufactured and can be commercialized to make profit. The raw material required is free of cost and easy to find because we are recycling the plastic.

- 18. After completing our project we can conclude that the plastic injection machine can be constructed in less cost. If any part in our project breaks or gets damaged then we can replace it easily. It does not require any special skills to operate the machine, except for the electronic connections included in the project. The Electronics circuit is easy to understand and anyone that can understand the given circuit diagram, the person can without any difficulty assemble the electronics. All the parts that have been fabricated require only basic fabrication skills, and no special purpose machines are required to perform these. All the equipments can be found in any basic workshop. This machine is hand operated so it does not require any prime mover, only electrical supply is given to the band heaters to heat it.
