Abstract


The demands of the functional aspects and the economic value of manufactured products to encourage the development of multi-material sintering process. But in its realization, various problems emerging techniques, including the determination of the type of material that can be sintered, non-uniform shrinkage phenomenon, and the bonding mechanism between different grains of unknown material. This study was conducted to determine the mechanism of bonding between the grains and calculate the shrinkage that occurs based on the grain due to the implementation of the sintering process. In practice, this study pursued through two stages. The first stage in the form of observations of the two grains with similar material (the material used is polyethylene). While the second phase in the form of observation of grains of polyethylene (PE) with a grain sintered poly vinyl chloride (PVC). Observations were made at isothermal conditions and periodically done shooting so the bonding process can be visualized. Based on the image data that has been retrieved, the volume shrinkage analysis can be done by calculating the projected area of ??the particle. From the research that has been done, the volume shrinkage that occurs on sintering material (PE with PVC) at an isothermal temperature of 1100C is equal to 20.42%

Key Word: mechanism bond, sintering, polyethylene, poly vinyl chloride
