Design and Manufacture of Injection Mould for Flat Drippers using Hot Drop Technology

Drip irrigation impacts prominently in proposed solutions to the water crisis. Earlier Inline and Outline drippers were used which had comparatively higher material cost & lower efficiency. Later, Round Drippers came into use which had Adequate efficiency but higher material cost because of the bigger size. So as a solution to this lately Flat Drippers have been introduced. Flat Drippers have very small size hence less material cost. Flat Drippers are manufactured using Plastic Injection Molding Process. Plastic Injection Molding is a process of melting plastic pellets (thermosetting/thermoplastic polymers) that once malleable enough, are injected at pressure into a mold cavity, which fills and solidifies to produce a product. Flat Drippers with zero runner wastage, zero rejections and the least possible cycle time. Hence, increasing the Production rate as well as it maintains the quality and consistency of the product. In the scope of this project the main aim is to Design and Manufacture Injection Mold (Hot Runner) for Flat Drippers to produce a standard discharge of 4 liters of water per hour in a single dripper. So, we will design and manufacture a mold of 32 cavity with 2 hot drops in such a way that the dripper meets the standard discharge parameters.
