Abstract
PURPOSE: To prevent the occurrence of deterioration and scorching in epoxy resin coating owing to oxidation by performing annealing under the specific conditions at the time of inserting an annealing process on the way and deep drawing an Al alloy blanked blank material having the epoxy-base coating.
CONSTITUTION: A coil material 20 to be carried into a factory is a sheet of Al alloy of 0.3W1mm thickness and has the coating of an epoxy-base resin on both sides. This blank material 20 is blanked in the 2nd process to become a blanked blank material 21 which is thence deep drawn by way of the 3rdW5th processes to be made into bodies 24, 25. These bodies are further subjected to the 6th process forming and the 7th process trimming. Thence, in the annealing of the 8th process, the bodies undergo annealing for 1W3min at 250W300°C in a continuous annealing furnace. After this, they go through the 9th process bulging and the 10th process seaming etc. and the production is completed by shipping of the 15th process.
