Plastic bucket molding process: The process involves feeding the raw material to the machine through a hopper. The barrel is heated to melt the material, which is injected into the bucket mould halves by the forward movement of the screws into the cavity. The bucket mould cavity is cooled by passage of water at ambient or low temperature to freeze the molten material. The pressure of the screw is held for some time and then it retracts by screw rotation. At the end of the moulding and cooling cycle, the bucket mould halves open and the moulded bucket is extracted manually or automatically. Thus the entire moulding cycle comprising injection, holding the injection pressure, cooling and the idle time for extracting the moulding is completed.
