Experimental Study on Mold-Lay Filament instead of Wax in Investment Casting Process

Abstract

Metal casting with investment casting method is metal casting which has the ability to produce accurate parts and has a controlled fineness. Current technological developments are very influential in the development of investment casting. One of them has been found mold-lay filament as a substitute for wax, which is now wax is one of the main components in investment casting process. Mold-lay filament is printed using a 3D Printer machine. In this study, the wax in the investment casting process was replaced by a mold-lay filament with the specifications 0.75kg / 0.55 lb of 1.75mm MOLDLAY filament, prints at temperatures of 170-180 ° C. The result show that mold-lay flutes are also able to come out well from slurry molds, but require more time than wax, this is because one of the plastic mold-lay compositions, which takes a long time for the moldlay fillment to come out of the mold. Further research suggestions are needed further testing in terms of roughness of the product with moldlay filament and compared with wax. This will also see if there are any remaining moldlay filaments from the mold.

Influence of Different Wax Hardening Agents on Surface Roughness of Refractory Cast Investment Materials

“…Thirty specimens were divided into three groups according to the dipping in hardening wax agents as follows [17]: ▪ 10 specimens dipping in bees wax for 10-15 seconds ▪ 10 specimens dipping in carnauba wax for 10-15 seconds ▪ 10 specimens dipping in ceresin wax for 10-15 seconds After the dipping process, all specimens were placed on paper one minute for drying and kept in a box at room temperature to carry out the same testing that we examined previously before dipping.
