Injection Molding Hand-Press Design and Analysis Using Solidwork

Injection molding is a method of forming a thermoplastic/composites material that is melted by heating and then injected into a mold so that the thermoplastic material can harden. The use of plastics is not only caused by the need for efficiency, as well as technological advances in the field of material engineering or manufacturing technology from the material itself. In this study, a hand-press injection molding machine was planned with the working principle of the lever being applied so that the transmission would transform the force to the injector so that the molten thermoplastic and composite material would come out into the mold. When the force is applied to the hand-press injection molding is analysed using Solid works and the mold design used refers to the dimensions of the ASTM D 3039 standard. For the tensile test, ASTM D 6110 for the impact test and ASTM D 695 for the bending test. Construction components of hand-press injection molding machine using ST 60 material, mold for tensile testing specimens, bending testing and impact testing using Al 7075 material, heating cylinder tube using Al 7075 material, the force given to the 200kg suppressor lever transmitted on the suppressor shaft obtained 0.29MPa. The maximum voltage at construction is 332 N/mm2 with a safety factor of 2.12 and a deflection of 13.09 mm.
