Abstract

Plastic waste is one of the environmental problems in Indonesia. Plastic waste is a type of waste that is difficult to decompose, so it needs special handling for processing the problem. One alternative offered is by making a plastic chopper machine. One of the manufacturing of a machine is to design and analyze the components used. The blade is one of the important components of a plastic chopper. Model simulation of the blade itself needs to be done to analyze the performance of the blade during the performance of the machine. Simulation modeling is done using CAE software.. The form of meshing in the blade model is using tetrahedral and the meshing ratio is close to 1. The results obtained from the blade modeling process are the maximum Von mises stress on the loading of 300N, 500N, and 700N respectively at 6.752 x 10-3 MPa, 2.845 x 10- 3 MPa and 1,575 x 10-3MPa. While the amount of displacement in the variation of loading 300N, 500N, and 700N respectively has a value of 6.752 x 10-2 mm, 1.125 x 10-1 mm and 1.575 x 10-1 mm. The safety factor in this simulation is produced which has a value of 15, which means it is safe for all loading variations because it has a value of more than 1.

Abstract

The conventional cooling process was chosen because of the better estimation of manufacturing times and lower manufacturing costs. One alternative to minimize the decline in quality in plastic products is by using a conformal cooling process. This study will compare the contours of the fluid flow pattern between conventional cooling channels and conformal cooling channels. Case study on a box-shaped product made of PP material which has a melt temperature of 205 ° C. 3D product images were made with Solidwork 2017 software and process simulation using fluent 19.0 software. The results showed that the temperature flow pattern in the conformal channel resulted in a temperature absorption of around 303.2K while the conventional cooling channel was around 302.5K. Then the coolant channel that experiences high pressure drop occurs in the conformal cooling channel around 88888.9 pascals and the conventional cooling channel around 355555.6 pascals.
