Abstract

This research goal is to determine the effect of temperature and screw angle to extrusion speed with High Density Polyethylene as Material on Single Screw Extrusion Machine. On this research use 2 factor, first Temperature with 160°C, 170°C, and 180°C. and the second one is Screw Angle with 0°, 15°, 25°. The roller and puller are setted up to 16 Rpm, data from the research analyze with ANOVA method. And results from the data researcher got the fastest on Screw Angle 25° with 170°C Temperature. And the slowest on Screw Angle 0° with 160°C Temperature. The conclusion that researcher got is Temperature doesn’t effect on extrusion speed because it doesn’t significant, Whereas the Screw Angle have an effect on extrusion speed.   Keywords : Extrusion Machine, Temperature, Screw Angle, ANOVA, Speed.

Abstract

This study aims to make a rubber-based fire seal with a diameter of 32.60 mm using a Compression Molding tool. Compression Molding itself is a set of printing tools by heating and pressing. The scheme of the basic processes consists of heating a charge (thermostat and reinforcement) to a certain temperature, in the mold cavity and then pressing it with a certain pressure.The first process begins with tool preparation and mold making, then rubber is made into a 32.60mm diameter fire seal. After everything has been prepared, then cut the rubber into small pieces to meet the volume of the seal in the mold and put the rubber into the mold. Press the mold using a  re using the thermostat. After completion, the measurement of seal shrinkage includes the inside diameter, outside diameter, and seal thickness and then compared with the mold size, so that conclusions can be drawn. The calculation is influenced by the density of the structure after the testing process.
