Most of the fishermen in Indonesia, using pumps to drain water in the ship. The use of pumps insea water often lead to rapid corrosion, especially on the impeller. Impeller manufacture of plasticmaterials is an alternative to solve this problem. Stages in the designing mould of plastic impeller is with3D and 2D drawing, choose a suitable polymer material, making mold of product, selecting componentsof mold and simulating the result. In designing mould of plastic impeller used software to simulate theplastic mould with mould parameters plastic inserts to get the best results before the completion ofproduction. As for plastic injection machine that is used to clamp force 1000 ton capacity with 8 pieces ineach injection products and using nylon material, 281,1oC temperature parameters, 62 sec of cycle timeand 80,552 MPa pressure.

Packing pressure directly influences quality of the plastic part. It is an important stage of plastic injection molding. This paper introduces the packing process.CAE software Moldflow provided the possibility to simulate the flow process of the plastic air intake manifold at different pressure and to predict the position of air traps. Packing pressure is determined by comparing analysis results and avoided mold adjustment and mold repairing. Analytic result shows that packing pressure at 70MPa can make the maximum injection pressure, melt flow rate, the required maximum clamp force smaller. And at that time, The air traps situation is also better. Practice proves that it is perfect of the finished sample of the plastic air intake manifold on basis of simulation.

Abstract AMPCO 940 is a precipitation-hardening copper-nickel-silicon-chromium alloy developed for resistance welding and other applications now using the 1% beryllium-copper alloys. The heat-treated alloy is capable of meeting the RWMA (Resistance Welder Manufacturers Association) Class 3 minimum requirements-95,000 psi tensile strength, 90 Rockwell B hardness and 45% IACS electrical conductivity. Potential applications include resistance welding tips, wheels and fixtures. A major use is in plastic injection molding. AMPCO-TRODE 940 is used for repair welding and overlays. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as casting, forming, heat treating, machining, and joining. Filing Code: CU-434. Producer or source: Ampco Metal Inc. Originally published as Ampcoloy 940, April 1982, revised March 1993.
