Investigation of mould design and process parameter optimisation of plastic injection moulding for thin wall part

In plastic injection moulding industries such as automotive, packaging and medical, demands for thin wall parts increases for the reason of light weight, lower cycle time, lower part cost and higher productivity. However, a lot of challenges faced by the moulders since the mould and processing param...
