The diagram illustrates the production and quality control process for plastic products, beginning with molten plastic and ending with the packing and distribution of the finished items.
Overall, the process involves multiple stages of moulding, inspection, and sorting, with mandatory quality control at each step to ensure the final products meet the required standards.
First, the molten plastic is applied into three different colours of mould: red, blue, and yellow. Then, the resistance of the mould is determined by the quality control department, using a machine. However, if it doesn’t met the requirements for strength, the mould would be disposed of.
Those that passed the test will be sorted manually. Categorized by the composition of the colours, either mixed or single, are then checked again to verify the composition, depth, shade of the colour. Those that passed the test would be packed and dispatched to stores for sale
