PROBLEM TO BE SOLVED: To enhance the creep resistance at use of an air conditioner or the like, in a blast fan made of synthetic resin using acrylonitrile styrene resin (hereinafter abbreviated as AS resin) or heat-resistant polystyrene resin (hereinafter abbreviated as heat-resistant PS resin), and to enhance the moldability at molding of a fan and also, enhance the productivity, in, especially, heat- resistant polystyrene resin. SOLUTION: A fan is made, using synthetic resin material where GF of long fiber reinforced pellet 1-6 mm in length is mixed by 20-40 wt.% in AS resin or heat-resistant PS resin, and it is annealed within the temperature range of 80-100 deg.C. |
