电冰箱制造行业的竞争越来越激烈，为了使产品在价格上获得绝对的优势，就必须降低冰箱的整体制作成本。在制冷行业中铜管以其优良的传热性能和弯曲成型性能占有举足轻重的地位，但随着材料科学的高速发展，邦迪管的制造技术日益成熟，由于它具有良好的密封性能和低廉的价格渐 The competition in the refrigerator manufacturing industry is getting fiercer and fiercer. In order to obtain the absolute superiority in the price of the products, the overall production cost of the refrigerator must be reduced. In the refrigeration industry, copper tubes occupy a pivotal position for their excellent heat transfer and bending properties. However, with the rapid development of materials science, the manufacturing technology of Bondi tubes has become increasingly mature due to its good sealing performance and low cost Gradual price
