GAS ASSISTED INJECTION MOLDING OF A VACUUM CLEANER BODY

摘要

Gas-Assisted-Injection-Molding (GAIM) was applied to a vacuum cleaner body made of PP that had a higher shrinkage and a lower strength than ABS. The CAE analysis was carried out to examine the factors in the mold design and processing such as the gas injector location, the gas channel size, the gas pressure level and profile, etc. Although the mold was machined according to the analysis result, actual molding conditions were optimized again with Taguchi method because the CAE analysis could not reflect the complexity of the actual process. The optimized molding conditions agreed well with the result of the CAE analysis.
