Kaji Optimasi Desain Cetakan Injeksi Moulding pada Unit Pengolahan Limbah Plastik Dinas Kebersihan dan Pertamanan Kota Banda Aceh
Abstract: High impact of
product damage by injection molds process on polymer waste processing unit was
seriously affected to quality and sustainability production. In this study
effect of injection mold design was minimized by investigated and redesign
injection molding system. The main equipments of injection molding system which
is available at Unit Pengolahan Limbah Plastik Dinas Kebersihan dan Permanan
Kota Banda Aceh are polymer waste cutting, splitting and cleaning devices and
injection molding machine. According to observation conducted previously on
current injection molding product and mold found that failure of product caused
by mis-design of mould. Products defects occurred are sink mark, weld line and
air trap. Mold-Flow software was used to modeling and simulating injection mold
process. Based on simulation result and discussion found that defected products
have been able minimized. By modifying sprue location and redesign mold,
products defect minimized and injection pressure still remain to push polymer
to mold inlet at range 0,72-0,48 Mpa
Keywords: Injection molding
system; optimization sprue-nozzle location; mold design and molding defects
